Accordingly, the information disclosure statement is being considered by the examiner. Priority Acknowledgment is made of applicant’s claim for foreign priority under 35 U.S.C. 119 (a)-(d). The certified copy has been filed in parent Application No. CN202110922415.4, filed on 08/12/2021. Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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. Claims 21 and 28-30 are rejected under 35 U.S.C. 103 as being unpatentable over Wong et al [US 2012/0256802 A1].

Claims 31 and 34-36 are rejected under 35 U.S.C. 103 as being unpatentable over Lindenmeier et al [US 2010/0302112 A1] In regards to claims 31. Lindenmeier discloses an electronic device comprising an antenna structure, wherein the antenna structure (Fig. 5) comprises: a first antenna element, wherein the first antenna element comprises a slot and a first feed point; and (Fig. 5, slot 3 with corresponding feed point 7) a second antenna element, wherein the second antenna element comprises a radiator and a second feed point, (Fig. 5, dipole radiator 1 with corresponding feed point at location 8) PNG media_image3.png 516 652 media_image3.png Greyscale wherein the slot and the radiator extend in a first direction and are spaced apart in a second direction, the second direction is perpendicular to the first direction, projections of the slot and the radiator in the second direction at least partially overlap, (Fig. 5, the dipole 1 and slot 3 are parallel and overlapping) a spacing distance between the slot and the radiator in the second direction is less than a quarter of a first wavelength or a quarter of a second wavelength (Paragraph [0040] the height of Fig. 1, the spacing of the dipole, is one quarter of the free space wave length), the first wavelength corresponds to a first operating frequency band of the first antenna element, and the second wavelength corresponds to a second operating frequency band of the second antenna element, (Paragraph [0040] both the slot and dipole have the same frequency as dipole and slot) the first feed point is configured to feed the first antenna element, and (Fig. 5, feed point 7 feeds the slot) wherein the second feed point is disposed in a central region of the radiator, or the second feed point is disposed at an end of the radiator, and the second feed point is configured to feed the second antenna element, and (Fig. 5, location 8 of the feedpoint of the dipole is in center of dipole 1) wherein the first operating frequency band of the first antenna element is the same as or adjacent to the second operating frequency band of the second antenna element (Paragraph [0040] both the slot and the dipole have the same frequency as both antennas form a circularly polarized antenna which in the art implies that both have the same frequency) Lindenmeier does not specify wherein the first feed point is disposed at an end of the slot Lindenmeier discloses wherein the first feed point is disposed at an end of the slot (Paragraph [0054] “It changes toward smaller values with an increasing distance 16 from the center Z. In the interests of better adaptation to such line structures, it is therefore advantageous, according to the invention, to select the distance 16 accordingly. In this connection, fulfillment of the phase and power conditions takes place, according to the invention, in the part of the line conducted between the parallel branching of the antenna line 11 and the slot radiator connection location 7, on the one hand, and toward the dipole connection location 8, on the other hand.”). It would have been obvious to one of ordinary skill in the art before the effective filling date of the invention was made to modify Lindenmeier with wherein the first feed point is disposed at an end of the slot for purpose of better adaptation to such line structures, it is therefore advantageous, according to the invention, to select the distance as disclosed by Lindenmeier (Paragraph [0054]). In regards to claims 34. Lindenmeier discloses the electronic device according to claim 31, wherein a first electrical length of the slot is the first wavelength (Lindenmeier Paragraph [0033]), and a second electrical length of the radiator is the second wavelength (Lindenmeier Paragraph [0032]).

Allowable Subject Matter Claims 37-39 are allowed. The following is an examiner’s statement of reasons for allowance: In regards to claims 37-39, “a first electrical length of the first radiator is the first wavelength or a second electrical length of the second radiator is the second wavelength, wherein a first electric field generated by the first antenna element is orthogonal to a second electric field generated by the second antenna element, or a first current generated by the first antenna element is orthogonal to a second current generated by the second antenna element, and wherein the first operating frequency band of the first antenna element is the same as or adjacent to the second operating frequency band of the second antenna element.” as shown in claim 37. Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Claims 22-27 and 32-33 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: “wherein that the first operating frequency band is adjacent to the second operating frequency band includes that a difference between a start frequency point of the first operating frequency band and an end frequency point of the second operating frequency band is less than 10% of a center frequency of the first operating frequency band, and a first frequency of a first frequency point in the first operating frequency band is greater than a second frequency of a second frequency point in the second operating frequency band” as shown in claim 22. “wherein a spacing distance between a first virtual symmetry axis of the first slot and a second virtual symmetry axis of the second slot in the first direction is less than a quarter of the first wavelength or a quarter of the second wavelength.” as shown in claim 23 “wherein a spacing distance between a first virtual symmetry axis of the slot and a second virtual symmetry axis of the radiator in the first direction is less than a quarter of the first wavelength or a quarter of the second wavelength.” as shown in claim 32.
