Abstract
En 中文
This letter proposes reflectionless linearly and circularly polarised patch antennas based on loading complementary absorptive branches. By establishing the equivalent circuit model of a conventional patch antenna, the complementary absorptive branch could be designed to dissipate the out-of-band energy through the grounded resistor, thereby achieving the reflectionless performance. Based on this concept, reflectionless linearly and circularly polarised patch antennas are designed and fabricated. Both antennas operate at 3.5 GHz. Measured results indicate that the linearly polarised patch antenna has a wide reflectionless frequency range of about 105% (1.71-5.4 GHz), with a peak radiation gain of 8.25 dBi. The circularly polarised patch antenna has a reflectionless frequency range of 68% (2.07-4.44 GHz), with the axial ratio (AR) bandwidth of 4.8%, stable radiation of right-handed circular polarisation (RHCP), and a peak radiation gain of 8.02 dBic.
