“…In the array antenna with a narrow spacing between the elements, so that there is a limited installation area for the feed circuit, realization of such feed circuits is difficult, particularly in phased arrays for a wide-angle beam scanning. Also, procedures to realize a low cross polarization with a single antenna element have been proposed [2,9,10]. Each one has the problem that the optimum design condition for a low cross polarization is not given in a form with a good perspective.…”

SUMMARYIn this paper, a design method by a feed point perturbation is proposed to obtain a low cross polarization characteristic in dual-polarized patch antennas. In the present design method, the cross polarization generated by the mutual coupling between the orthogonal feed points is canceled by the cross polarization newly generated by the feed point perturbation. This design method is simple and does not require any special feed circuit. Hence, the method is effective for array antenna elements with a limited mounting area. Also, the optimum design conditions under the proposed design method are analytically derived. From the numerical results by the FDTD method and the experimental results, the effectiveness of the proposed design method and its optimum design condition is confirmed.

“…Furthermore, a method for perturbation of feed points [12] uses cross-polarization generated by feed point perturbation to cancel out cross-polarization generated by mutual connections between dual feed points. Elsewhere, a method combining slot connection feeding and bin feeding [13], and a method that puts the patch in the shape of a cross [14], have been reported. All of these methods are effective for decreasing cross-polarization in the patch antenna's horizontal plane and vertical plane.…”

SUMMARYIn this paper, we propose a method for decreasing cross-polarization in the tilt plane by optimizing the dielectric substrates of dual-polarized patch antennas. At the same time, we clarify the limit values for the cross-polarization level. First, we use a cavity model of the patch antenna to find cross-polarization dielectric characteristics in the tilt plane. We learn from this that the direction of cross-polarization increase or decrease in relation to the dielectric is reversed during horizontal polarized excitation and vertical polarized excitation. Therefore, if the cross-polarization level during horizontal polarized excitation and vertical polarized excitation is the same dielectric, the lowest crosspolarization level can be obtained in conditions where both horizontal polarization and vertical polarization are decreasing cross-polarization. Next, we investigate the case where parasitic elements are mounted on the patch antenna, and use the FDTD method and test to show that our method is valid. In addition, if the patch is positioned perpendicularly to the horizontal plane, we show that the optimum dielectric remains virtually unchanged in the tilt plane up to about 15° from the horizontal plane.
