摘要

本文介绍了一种二维（2D）元面天线阵列，由顶部金属化薄槽耦合的蘑菇状单元组成。天线通过采用基底集成波导技术设计的功率分配器馈电。因此，天线结构的设计完全是最新的集成版本。阵列在方位面上显示出波束转向，由输入矩阵边缘特定端口的信号幅度控制。这种天线的主要优点是无需使用标准二维天线阵列中的移相器。我们设计、制造并实验测试了两种天线版本。光束可在方位角 360°（90°）范围内转向。通过将频率从 21 千兆赫提高到 23.8 千兆赫，可在 40° 范围内将波束从仰角方向转向俯角方向。通过在两个相邻端口以相同振幅同时激励天线，可将这一间隔缩小到 30°。

2D leaky-wave antenna with controlled direction of radiation in the azimuthal plane

This paper presents a two-dimensional (2D) metasurface antenna array composed of mushroom cells coupled by thin slots in the top metallization. The antenna is fed through power dividers designed in substrate-integrated waveguide technology. The antenna structure is therefore designed in a fully up-to-date integrated version. The array shows beam steering in the azimuthal plane controlled by signal amplitudes fed into particular ports at the edges of the matrix. The main advantage of this antenna is no need to use phase shifters applied in standard 2D antenna arrays. Two antenna versions have been designed, fabricated, and experimentally tested. The beam can be steered within 360° (90°) in azimuth. The steering of the beam in elevation from backward to forward directions within 40° is done by changing frequency from 21 up to 23.8 GHz. This interval is reduced to 30° by exciting the antenna simultaneously at two adjacent ports at the same amplitude.

期刊介绍： The prime objective of the International Journal of Microwave and Wireless Technologies is to enhance the communication between microwave engineers throughout the world. It is therefore interdisciplinary and application oriented, providing a platform for the microwave industry. Coverage includes: applied electromagnetic field theory (antennas, transmission lines and waveguides), components (passive structures and semiconductor device technologies), analogue and mixed-signal circuits, systems, optical-microwave interactions, electromagnetic compatibility, industrial applications, biological effects and medical applications.
