摘要

A miniaturized circularly polarized microstrip antenna array with sequential-phase (SP) feed is presented. Attributed to the slotted metal walls surrounding the SP feed and the internally slotted patch array with parasitic rectangular patches, the key performance indicators of antennas are greatly improved, such as gain and impedance bandwidth. The numerical results of designed antenna simulated by ANSYS HFSS show that the impedance bandwidth is about 11.89% (5.41-6.09GHz) for the S-11 = -10 dB matching criterion, the 3-dB Axial Ratio (AR) bandwidth is about 13.26% (5.64-6.44GHz), and the peak gain can reach to 11.86 dBi at 6.09GHz. When the center frequency of proposed antenna is operated at 5.87GHz, the available bandwidth is 7.71% (5.64-6.09GHz). Based on this, the AR bandwidth is about 450MHz.
