This letter presents a method to convert the split dual-beam into a single one in the quasi-E-plane with low cross-polarization level for the pin-loaded fundamental EH 0 -mode microstrip leaky-wave antennas (MLWAs). By exciting a pair of them under differential operation with proper configuration, the ϕ -polarized dual beams can be reshaped to achieve a single-beam radiation, so as to widen its potential application. The proposed method for transversal single beam still preserves the merits of the original pin-loaded EH 0 -mode MLWA with simple structure and freely designed narrow width. A prototype MLWA with single-beam radiation in the quasi-E-plane is designed, fabricated, and measured. Good agreement is attained between simulated and measured results, and thus validates the unique feature of the proposed method in design of single-beam pin-loaded EH 0 -mode MLWAs.

差分操作下耦合微带线上的横向单波束EH 0模式微带泄漏波天线

这封信提出了一种方法,用于将引脚加载的基本EH 0 模式微带漏波天线(MLWA)在准E平面中转换为具有低交叉极化水平的双波束 。通过以适当的配置在差动操作下激励一对,ϕ 可以对偏振双光束进行整形以获得单光束辐射,从而扩大其潜在的应用范围。所提出的横向单光束方法仍然保留了 结构简单,自由设计的窄宽度,原始销钉负载EH 0模式MLWA的优点 。设计,制造和测量了在准E平面上具有单光束辐射的MLWA原型。仿真结果与测量结果之间取得了良好的一致性,从而验证了该方法在单束销钉加载EH 0 模式MLWA设计中的独特之 处。
