摘要

提出了一种基于工作频率为3.6 GHz贴片天线的4元2×2子阵列。子阵列可以提供4个极化。该设计由两个基板(ro450b)组成，其8r = 3.66，顶层和底层的高度分别为1.524 mm和0.762 mm。所研究的技术需要在贴片内增加两个正交槽，以允许放置PIN二极管并将其连接到位于底层的偏置电路。该模型提供了左旋圆极化(LHCP)、右旋圆极化(RHCP)和两种线性极化(LP_ON和LP_OFF)的天线极化类型。获得的最大增益为9.63 dB，带宽为145 MHz。

A 4-element sub-array with 4-polarization modes

A 4-element 2×2 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 8r = 3.66 with heights of 1.524 mm 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 two cases of linear polarization (LP_ON and LP_OFF). The maximum obtained gain was 9.63 dB and the bandwidth was 145 MHz.
