It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Hendrix by adding a second calibration circuit connected between two adjacent antennas of the at least two antennas, and the second calibration circuit is configured to calibrate phases and amplitudes between different antennas. This modification would provide optimized antenna beams of the communication system (see Li-2, col. 9, lines 13-17).
Claim 38 is rejected under 35 U.S.C. 103 as being unpatentable over the modified Hendrix as applied to claim 34 in view of Balanis (“Antenna Theory Analysis and Design”, Second Edition, John Wiley & Sons, 1997).
Regarding claim 38, as best understood, the modified Hendrix teaches the communication system of claim 34.
The modified Hendrix teaches both the front radiating element array and the side radiating element arrays are part of a plurality of radiating element arrays.
The modified Hendrix does not teach explicitly a first radiating element array of the plurality of radiating element arrays is used as a baseline.
Balanis (Fig. 6.5, p. 258, eq. 6-7a) teaches an array of radiating elements, wherein a first radiating element (element number N) is used as a baseline for determining the phases of the rest of the radiating elements (elements numbered 1, 2, 3, 4 …) in the array by using the separation between the radiating elements and the angle of the desired direction of a transmitted or received electromagnetic wave. Furthermore, it is well-known in the art, that the principle taught by Balanis is applicable to a plurality of radiating element arrays, wherein the first radiating element array of the plurality of radiating element arrays is used as a baseline for determining the phases of the remaining radiating element arrays.
It would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Hendrix so that the first radiating element array of the plurality of radiating element arrays is used as a baseline as taught by the known scientific method of Balanis. This modification would allow to determine the phases of radiating element arrays of the plurality of radiating element arrays for determining the incident angle of an electromagnetic wave arriving at the antenna system.
