摘要
微带贴片天线成本低,便于生产,通过采用公共地平面孔径耦合结构,还具有隔离抑制馈电辐射的特点,但在应用过程中最主要的障碍是微带贴片天线的带宽有限。基于此,研究了通过用偶极子构成对数周期阵列天线,并把这个原理用于微带天线线性阵列,带宽可以达到几个倍频程。
The microstrip antenna is easy to produce and has a low cost.It also has the advantage that the radiation of the feed can be isolated or restrained.The main problem in engineering applications is that the bandwidth of the microstrip antenna is limited.On the basis of this,this paper studies the use of dipoles to constitute the logarithmic array antenna and applies this principle to the microstrip antenna so that the bandwidth can reach several octaves.
