摘要：

A 4-element 2x2 sub-array based on patch antennas operating at 3.6 GHz is proposed. The sub-array can provide 4 polarizations. The design consists of two substrates (RO4350B) with epsilon(r) = 3.66 with heights of 1.524 nun and 0.762 mm for the top and bottom layers respectively. The investigated technique required adding two orthogonal slots inside the patch to allow placing PIN diodes and their connection to the biasing circuitry which is located at the bottom layer. This model provides four types of antenna polarization which are left-handed circular polarization (LHCP), right-handed circular polarization (RHCP) and vo cases of linear polarization (LP_ON and LP_OFF). The maximum obtained gain was 9.63 dB and the bandwidth was 145 MHz.
