The coaxialfeed is an important dual-band feed used in reflector antennas. The inner conductor of the coaxialfeed is the high frequency feed, and the coaxial zone is the low frequency feed.
The thesis deeply analyzes the factors which affect the bandwidth of microstrip antenna and studies the influence of coaxial probe which is applied to feed to microstrip antenna.
深入分析了影响微带天线带宽的因素，研究了同轴探针馈电微带天线的同轴探针对微带天线带宽的影响。
