Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 1-20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
The disclosure of the aforementioned prior-filed application fails to provide adequate support or enablement in the manner provided by the first paragraph of 35 U.S.C. 112 for one or more claims of this application: claims 1-20.
Specifically, claims 1, 9 and 10 includes limitations that are not disclosed or provide adequate support or enablement in the specification. Some exemplary limitations from these claims are herein recited for further reviews: "calculating a correlation coefficient between the transmitting antenna and the receiving antenna.”
The specification fails to properly describe how does a correlation coefficient between the transmitting antenna and the receiving antenna being calculated? And, the written description fails to disclose the corresponding structure, material, or acts for the claimed function. The specification only described “the correlation coefficient between the transmitting antenna and the receiving antenna can be calculated according to a formula for calculating the correlation coefficient” in paragraph [0021], and “the correlation coefficient between the transmitting antenna and the receiving antenna is calculated through a preset formula for calculating the correlation coefficient” in paragraph [0029]. There is not a possession of description of how it done or how does it perform the calculation of correlation coefficient between the transmitting antenna and the receiving antenna?
Therefore, the claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention.
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Regarding claims 1, 9 and 10, the limitations recite “transmitting a first signal through a transmitting antenna,” “receiving a second signal through a receiving antenna,” “calculating a correlation coefficient between the transmitting antenna and the receiving antenna,” and “adjusting operation states of the transmitting antenna and the receiving antenna” are unclear and leaves the reader in doubt as to the meaning of the technical feature to which it refers. It is unclear that how does it transmit a first signal through a transmitting antenna? How does it receive a second signal through a receiving antenna? How does it calculate a correlation coefficient between the transmitting antenna and the receiving antenna? And how does it adjust operation states of the transmitting antenna and the receiving antenna?
Regarding claims 7 and 15-18, the limitation recites “adjusting the correlation coefficient between the transmitting antenna and the receiving antenna through a tuning circuit to enable the correlation coefficient subjected to the adjusting to be lower than the correlation coefficient before the adjusting” is unclear and leaves the reader in doubt as to the meaning of the technical feature to which it refers. It is unclear that how does it enable the correlation coefficient subjected to the adjusting to be lower than the correlation coefficient before the adjusting?
Regarding claims 8 and 19-20, the limitation recites “adjusting the correlation coefficient between the transmitting antenna and the receiving antenna through a tuning circuit to enable a data throughput rate to be greater” is unclear and leaves the reader in doubt as to the meaning of the technical feature to which it refers. It is unclear that what a data throughput rate? How does it enable a data throughput rate? And enable a data throughput rate to be greater than what?
The claims fail to recite sufficiently definite structure, material or acts for achieving the functional result recited in the claim to reasonably apprise one of ordinary skill in the art of the scope of the claims.
Claims 2-8 and 11-20 are depending on claim 1, and are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph as the same reason as stated above.
Note: for compact prosecution purposes, the examiner interprets the claims above as best understood in the rejection below.

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim 4 is rejected under 35 U.S.C. 103 as being unpatentable over Shimizu (U.S Publication No. 20110116404 A1) and in view of Yamaguchi et al. (U.S Publication No. 20190044568 A1).

A human interface (HI) 14 includes a data input device, a display, and the like for a worker. Data is input through the HI 14 as required and the state of the array antenna device is monitored on the display.

Yamaguchi does not explicitly disclose calculating a correlation coefficient between the transmitting antenna and the receiving antenna according to the first signal and the second signal; adjusting operation states of the transmitting antenna and the receiving antenna according to the correlation coefficient calculated.
Shimizu, on the other hand, for executing a communication on the basis of a frequency division duplex, has a first antenna, a second antenna, a first receiver for receiving a first radio frequency signal via the first antenna, a second receiver for receiving the first radio frequency signal via the second antenna, a transmitter for transmitting a second radio frequency signal via the second antenna, a power measuring unit for measuring a first power of a component of the second radio frequency signal in a received signal received via the first antenna, and a control unit for controlling a reactance between the first antenna and the second antenna so as to lower an amount of coupling between the first antenna and the second antenna on the basis of the measured first power, see abstract, fig. 1-10), and to implement a method of:
