Abstract: This paper presents a novel dual-band dual-polarization microstrip conformal antenna. First, the conformal antenna is composed of the rectangular microstrip patch unit. And the dual-band is achieved by changing the patch size. Secondly, the different radiation polarization is realized by changing the feed direction of the unit. Finally, according to the antenna unit arrangement form, we design of the feed network which based on the T shape power divider. The pattern roundness of antenna 1 and 2 is 3.56dB and 3.98dB, respectively. The gains are 1.1dBi and 0.85dBi, respectively. Both experimental and simulated results show that a good agreement with simulation results.
