摘要：
A technique to design a compact half mode substrate integrated circular cavity (HMSICC) cavity backed antenna is presented in this letter. The proposed antenna achieves left-handed circularly polarized(LHCP) using a crossed slot, The feeding meandered stripline on the middle layer are able to achieve better impedance match and axial ratio bandwidth. Measured results show that the prototype achieves a bandwidth of 10.5% for -10dB return loss, axial ratio(AR) bandwidth is about 3% with maximum gain of 6.5dBi. (c) 2016 Wiley Periodicals, Inc.
