摘要
Abstract
An ultra-wideband microstrip dual-level log-periodic antenna is proposed as passive anten-na, taper-line feed is used to achieve conversion from non-equilibrium to equilibrium, and to get 8~18 GHz bandwidth of standing wave 2 following with 8 pairs of dipoles.In the entire bandwidth, pattern is stable, and before-after ratio is less than -20 dB, the gain is greater than 7 dB.The simulation results are basically consistent with experimental results .This antenna can be used as ultra-wideband miniaturi-zation passive antenna.关键词
