摘要：
A novel structure to improve the cross-polarization characteristics of the shorted square microstrip antenna is presented. The square-ring patch is used as a parasitic element in the stacked position to tune the inout impedance, resonant frequency, cross polarization, and bandwidth of the shorted square microstrip antenna. As a result, 11% bandwidth and better than - 14.5 dB cross-polarization levels have been achieved. The theoretical results are compared with the experimental results. (C) 2001 John Wiley & Sons, Inc.
