摘要：
In this paper, a novel broadband and dual-polarized microstrip antenna is presented. The antenna unit is cascade-structured, with square radiation patch at the bottom and a circular aperture-coupled patch on the top. A common antenna with regular square aperture-coupled patch is also designed in this paper. By contrasting the results of calculation, the novel microstrip antenna has advantages in broadwidth, isolation and cross polarization, which is over -5 dB, better than the regulare ones. So it has much important value in projects. © 2009 by Editorial Department of Chinese Journal of Radio Science.
