Abstract

A novel leaky wave antenna (LWA) with integrated field-programmable microwave substrate (FPMS) unit cells is presented in this article. The proposed antenna consists of a Half Mode Substrate Waveguide (HMSIW), loaded with cross-shaped slots to generate the desired phase response and radiation characteristics. Using the agile FPMS technology, the substrate properties along one of the longitudinal edges of the antenna are varied, which allows the steering of the radiation direction at a single frequency. A total of 70-unit cells are integrated with the antenna at 12 GHz, resulting in a maximum beam steering of 72

$^\circ $

in simulations along the elevation. Experimental results of the fabricated prototype also demonstrate the practical viability of the proposed design concept with a total beam steering of 35°. The design presented in this research serves as a proof-of-concept, setting the stage for forthcoming advancements and refinements in the field of smart antenna systems using FPMS.

基于FPMS的波束可操纵半模SIW漏波天线

本文提出了一种新型漏波天线（LWA），该天线采用集成场可编程微波基片（FPMS）单元。所提出的天线由半模衬底波导（HMSIW）组成，该波导加载有十字形槽，以产生所需的相位响应和辐射特性。使用灵活的FPMS技术，沿着天线的一个纵向边缘的衬底特性是变化的，这允许在单个频率下控制辐射方向。在12 GHz的频率下，共有70个单元与天线集成，在沿仰角的模拟中，最大波束方向为72$^\circ$。制造的原型的实验结果也证明了所提出的设计概念在35°全波束转向的情况下的实用可行性。本研究中提出的设计是概念验证，为使用FPMS的智能天线系统领域即将取得的进步和改进奠定了基础。
