Waveguide-form multi-beam lens antenna has several shortcomings, such like large size and weight of feed source. According to such situation, a lens antenna applied to high altitude platform is designed. The proposed antenna uses printed Yagi-Uda antenna as feed unit and applies CST MICROWAVE STUDIO® electromagnetic simulation software to analyze. The proposed antenna is manufactured and tested in...
A kind of novel multiband monopole antenna with square-nested fractal is proposed and designed, which is nested with a series of similar square elements. The antennas can synchronously operate in multiple frequencies, covering the four required frequencies, 2.4GHz/3.5GHz/5.2GHz/5.8GHz, for WLAN/WiMAX application. The antenna surface currents are simulated by CST Microwave Studio®, a 3-dimension full-wave...
A printed TEM horn antenna with high gain fed by balanced microstrip line is proposed. The radiation part of the antenna consists of two symmetrical triangular metal slice branches printed on the FR-4 substrate with 1.5mm thickness. The two branches are fed by balanced microstrip line. The antenna is simulated by software CST MICROWAVE STUDIO® and the equivalent adopted dipole model is proposed to...
