摘要

提出了一种基于矩形槽接平面的l带和s带双宽带共面波导馈电三角形微带天线的新设计。提出了三角片顶角变化和微带线宽度随微带线长度变化的参数化研究方法。该配置在l波段可获得400mhz(>22%)以上的带宽,在s波段可获得2100 MHz(>55%)以上的带宽。该天线在双频段和宽带响应时呈现宽侧辐射方向图,在各自频段增益均大于4和2dbi。

Dual and wideband design of CPW fed rectangular slot backed inverted triangular microstrip antenna
A novel design of dual and wide band coplanar waveguide fed triangular microstrip antenna backed by rectangular slot ground plane in L-band and in S-band is proposed. A parametric study for variation in vertex angle in triangular patch and the effect of variation in strip width over length of the microstrip line is presented. The proposed configuration yields more than 400 MHz (>22%) of bandwidth in L-band and more than 2100 MHz (>55%) of bandwidth in S-band. The antenna shows broadside radiation pattern at dual and wide band response with gain of more than 4 and 2 dBi in respective frequency bands.
