A New Microstrip Patch Antenna with Enhanced Bandwidth and Wideband Harmonic Suppression
This paper presents a new type of microstrip patch antenna with bandwidth enhancement and harmonic suppression. A new dual-point feeding network is adopted to suppress the high-order harmonics, and a double-layer structure is introduced to enhance the bandwidth of the antenna. In the paper, the characteristics of high-order harmonics up to 2.8 times of working frequency are discussed, and the principle of harmonic suppression and bandwidth enhancement is analyzed in detail. Based on the analysis of the commercial full-wave simulator, i.e., ANSOFT HFSS, the results show that the antenna not only has good harmonic suppression effect, but also broaden the relative bandwidth of the microstrip patch antenna from 0.82% to 11.8%.
