✦ Synopsis

This paper presents the effect of the interaction between the switch and the antenna parameters on the cross-polarization of a dual polarization switching antenna. It is shown that the isolated antenna cross-polarization combines with the isolation of the switch giving place to a degradation of the polarization purity of the combined dual polarization switching antenna. Analytical expressions for the combination of the switch isolation and the antenna cross-polarization in the switched antenna element are given. Simulations and pattern measurements are presented. V

## Abstract The cross‐polarization suppression of dual‐polarization linear microstrip antenna arrays is investigated theoretically and experimentally. Four designs of 4‐element linear microstrip antenna arrays for suppressing cross‐polarization are presented by using the pair‐wise anti‐phase feedin

## Abstract This paper presents a design for stacked triangular patch antennas with two feeds for achieving dual‐polarized operations. The top radiating element of the stacked structure is a single‐feed, triangular, planar inverted‐F antenna (PIFA) with a V‐shaped slot, which can radiate an omnidir

## Abstract Experimental and simulated results for a dual‐port dual‐polarized microstrip antenna are presented. The antenna excites two orthogonally polarized resonant frequencies providing an isolation of ∼30 dB between the ports. The patch geometry consists of two circular arcs of different radii

## Abstract Two new configurations of patch antennas are introduced, which provide dual‐band and dual‐polarization operations. The two patches have a square and cross shape, and are printed on a single layer; the dual‐frequency and the dual‐polarization behavior is obtained by means of four narrow
