“…Besides, several leaky‐wave dual‐beam antennas with varied‐frequency‐scanning property are proposed in References [8–14] Although being superior in high gain of 9–13 dBi, these leaky‐wave antennas are always suffering from long length due to their traveling‐wave working mechanism. Dual‐beam grid array antennas 15,16 also suffer from large size. Aiming to achieve compact size and moderate gain, planar resonant structures have been taken into consideration to generate dual‐beam.…”

In this article, two coupled patch elements in central symmetry are used to produce a pair of even/odd characteristic modes with single‐/dual‐beams. It is found that the pointing direction of dual‐beam could be adjusted in both horizontal and vertical planes with unchanged polarization. Common‐fed configuration is adopted to effectively excite the odd mode and fully suppress the even mode. Modal impedance analysis is performed for the proposed antenna to determine the two feeding positions. A prototype antenna with its dual‐beam rotated by 45° in horizontal plane and inclined by 40° in vertical plane is fabricated and measured. The antenna possesses a 10‐dB impedance bandwidth of 0.73% and a radiation gain of 7.0 dBi.

“…Adjustment of pointing direction of dual‐beam at the fixed center frequency without changing polarization is seldom discussed in previous works 5–20 . To fill this gap, Section 2 proposes a structure consisting of two coupled patches in central symmetry to produce a pair of even/odd modes.…”
