Simultaneous measurements of copolarized and cross‐polarized signal components for two orthogonal linear polarizations were made at Crawford Hill, New Jersey, by using polarization‐switched 19‐GHz beacons on COMSTAR satellites. from polarization mismatch can vary between infinity and zero. To better analyze this problem, we can divide it into two interfuse groups: 1.2 Polarization Mismatch Loss For linear polarization, the mismatch loss is given by Г = cos2 (θ),.where θ is the angle between polarization vectors. The cross polar discrimination is defined as a ratio of the copolar component of the specified polarization compared to the orthogonal cross-polar component over the sector or beamwidth angle.
Despite port 1 has obtained a low lever cross polarization, the cross polarization of port 2 in this arrangement becomes very poor at angles greater than 10– of broadside direction in the x-z plane as illustrated in Fig. 2. This is caused by the spatial phase delay (¢`0 = k0¢xsinµ) formed The horizontal spacing between the arrays inside the radome and the arrangement of the antenna elements are optimized to minimize port-to-port isolation, cross-polarization levels, and the impact of the adjacent array on the co-polarization patterns of each port contributed to uncorrelated channels. The isolation level of better than 51 dB and cross-polarization level of less than 30 dB are achieved from the measurement results of the designed single element. To achieve better cross-polarization levels, the 2 2 element subarrays of the proposed unit cell, while Polarization transformation, and therefore polarization control, may be achieved in optical fiber by inducing birefringence equivalent to a quarter- and half-wave plates (e.g., by bending or squeezing the fiber, as described in Section II.B.1), and then rotating the birefringent sections with respect to each other.

The proposed antenna contains two pairs of T-shaped slots on the two bowtie-shaped patches separately. This structure changes the path of the current and keeps the cross polarization under -40 dB. By introducing two short pins, the isolation between the two ports The determined cross-polarization isolation can be used to adjust an antenna. A method of and system for determining cross-polarization isolation is described.
