摘要

提出了一种具有连续波束扫描能力的周期基板集成波导漏波天线。由氧化锆陶瓷块(ZCB)堆叠的横向槽结构周期性地加载在LWA的每个单元胞内。对于作为介质谐振器的ZCB，在原点等效电路中引入了另一个谐振网络。然后，我们改变ZCB的尺寸，使单元格的电抗分量在宽侧频率为零，因此，成功地抑制了开阻带。

SIW Leaky-Wave Antenna with Zirconia Ceramic Block for Suppressing the Open Stopband

In this paper, a period substrate integrated waveguide (SIW) leaky-wave antenna (LWA) with a continuous beam-scanning capability is proposed. Structure of the transverse slot stacked by zirconia ceramic block (ZCB) is periodically loaded in each unit cell of the LWA. For the ZCB functioning as a dielectric resonator, another resonant network is introduced to the origin equivalent circuit. We then change the dimensions of the ZCB to make the unit cell's reactance component to be zero at broadside frequency, as a result, the open stopband is successfully suppressed.
