摘要

提出并研究了一种具有稳定增益的低轮廓宽带微带天线。所述天线的辐射贴片由两排短针短接，并通过三个插槽分成6片。天线由微带线通过在地面上切开的插槽馈电。同时激发两种具有宽侧辐射的共振模式。该天线工作频带为4.05-5.86 GHz，相对带宽为36.5%，剖面为0.06 λ0 (λ0为自由空间中心工作波长)。它具有5.7-6.5 dBi的极其稳定的增益和稳定的辐射模式，在工作波段无零。

A Broadband Microstrip Antenna with Stable Gain

A low-profile and broadband microstrip antenna with stable gain is proposed and studied. The radiation patch of the proposed antenna is shorted by two rows of shorting pins and is divided into six pieces by three slots. The antenna is fed by a microstrip line through a slot cut on the ground. Two resonance modes with broadside radiation are excited simultaneously. The proposed antenna achieves a broad operating band of 4.05-5.86 GHz and the relative bandwidth of 36.5% with a profile of 0.06 λ0 (λ0 is the center operating wavelength in the free space). It has an extremely stable gain of 5.7-6.5 dBi and stable radiation patterns without null in the operating band.
