Abstract

Orthogonal static or fixed links with polarization multiplexing can be formed by using dual polarized antennas with a low cross coupling from one polarization to the other. This is limited by the level of achievable polarization purity of two orthogonal dual polarized antennas. Any practical antenna is inherently elliptically polarized, resulting in either circular or linear polarization impurity. This work exploits such impurity where simple semi directional elliptically polarized antennas are designed to have minimal cross coupling. Results show a dual polar static link can reach the capacity limit using elliptical polarization, which is not reached with linear polarization. Channel measurements both in free space and indoor environments were carried out from 2.2 to 2.4 GHz using a derived cross polar ratio to quantify the impact of multipath scattering on static links.
