摘要
Abstract
The ultra-short wave antennas are widely used in ships and aircraft. The miniaturization of antenna can improve its concealment and stability, so it is very important to design a miniature antenna. This paper presents a new Ultra-Short Wave antenna with broadband matching network and loaded lumped elements. The antennas integration design connects the broadband matching network made of microstrip circuit with the radiated element of antenna to reduce the length of antenna. It is simulated by Matlab and HFSS, and the genetic algorithm is used to optimize the specific values. The VSWR(Voltage Standing Wave Ratio) of the antenna (operating frequency 100 MHz-400 MHz) is below 3 in the whole band with omnidirectional radiation pattern in the horizontal plane. The physical length of the antenna is just 255 mm which meets the miniaturization requirements. The antenna is fabricated and measured. The antenna parameters measured are in good agreement with the simulated, which has realized the preliminary design goals.关键词
