摘要

通过引入空气区，提出了一种具有宽阻抗带宽的低轮廓介质谐振器天线。提出的DRA由两个对称槽馈电。通过在DRA内部插入空气区，可以对DRA模式进行激励和合并，从而拓宽阻抗带宽。该DRA可以实现45.8%的阻抗带宽，覆盖3.2-5.1GHz频段。同时，它具有非常低的轮廓，约为0.07λ0。在6.25 dBi左右获得相对稳定的增益。

Low-Profile and Broadband Dielectric Resonator Antenna By Using Air Regions

A low profile dielectric resonator antenna (DRA) with wide impedance bandwidth is proposed by introducing the air regions. This proposed DRA is fed by two symmetrical slots. The DRA modes can be excited and merged to broaden the impedance bandwidth by inserting air regions insider the DRA. This DRA can achieve impedance bandwidth of 45.8% covering the frequency band of 3.2-5.1GHz. At the same time, it has very low profile of about 0.07λ0. A relatively stable gain is obtained around 6.25 dBi.
