【摘要】 提出了一种高隔离度、低交叉极化的双极化宽带介质谐振器天线。该天线一线极化采用缝隙直接耦合馈电,另一个线极化采用平衡缝隙馈电。天线的端口隔离度高于51 dB,交叉极化电平低于–35 dB。两个端口上回波损耗小于–10 dB的阻抗带宽均大于16%。两个正交极化在中心频率的最大增益分别达到7.9 dBi和8.4 dBi。
【Abstract】 A wideband dual-polarized(DP) dielectric resonator antenna(DRA) with high isolation and low cross-polarization level is proposed. The dual orthogonal linear polarization is achieved by the combination of a slot-coupled feed at one port and a balanced-slot feed. The DP DRA demonstrates a port isolation exceeding 51 dB and a cross-polarization level of –35 dB. The fractional impedance bandwidth for two ports are more than 16% for the return loss of less than –10 dB. The antenna peak gains for the two orthogonal polarizations are 7.9 dBi and 8.4 dBi, respectively.
