This paper presents a dual linearly-polarized patch antenna with pattern reconfigurable characteristics. The antenna can achieve ±45° dual-polarization with three modes. By changing the states of switches, the maximum radiation direction points to +25°, -2° and -26° in the elevation angle (x-z plane), with 3dB beamwidth(More)
A two-port pattern reconfigurable three-layered Yagi-Uda patch antenna with ±45° dual-polarization characteristic is presented. A driven patch (DP) and two large parasitic patches (LPPs) are printed on the top side of the middle layer, and the middle and bottom layers share a common metal ground. Two microstrip feedlines printed orthogonally(More)
A dual-polarized multi-layer patch antenna with ±45° pattern reconfigurable characteristic is presented. The two-port antenna contains two same-size substrate layers, with a common ground between them. A driven patch and two parasitic patches are printed on the top side of the upper layer. Through two H-shaped slots in the ground, the antenna(More)
