Polarization diversity is becoming the need of the hour as more and more wireless applications use electromagnetic bandwidth. The recently deployed 5G and upcoming 6G communications will require multiple polarization antennas. Polarization diversity of an antenna adds to the stability of the connections, channel capacity, increased bandwidth and can be used as various channels. In this paper, a shared-aperture orthogonally polarized array is presented that can produce multiple linear and circular polarization without inboard switches or additional hardware. The polarization diversity is achieved through orthogonal aperture sharing. The array is designed at 11.5 GHz frequency and has a 3-dB bandwidth of 17%, peak directivity of more than 15 dB, cross-pol isolation of -40 dB, and 3-dB axial ratio bandwidth 10%.
