In this paper, metasurface antenna (metantenna) with one‐dimensional holographic concept is proposed and an example of producing 50° radiation beam angle at 16 GHz is taken to certify the metantenna operating principle. We first introduce one‐dimensional holographic theory to simplify the metasurface design. By this means, compared with the traditional two‐dimensional metantenna, the integral structure has fewer unit cells, simpler structure and the beam‐tilt is achieved as well. Simultaneously, to feed the metasurface above efficiently, the tapered microstrip line is modified by adding a sloping metal strip as a plane‐wave surface wave launcher, thus obtaining a smooth transition from Quasi transverse electromagnetic wave to transverse magnetic wave and a broad frequency band of impendence matching. A prototype is fabricated and tested at last. The measured radiation beam angle is 49° at 16 GHz, which approximates to the desired beforehand. On the other hand, this metantenna has a beam scanning angle of 24° to 63° from 13 to 17.5 GHz. The gain is about 13 to 15 dBi and the half power beam width is about 9° in the above frequency range. It has features of stable high gain, narrow beamwidth and high radiation efficiency.

一维全息概念的元天线设计

本文提出了一种具有一维全息概念的超表面天线（metantenna），并以在16 GHz频率下产生50°辐射束角的示例为例来验证metantenna的工作原理。我们首先介绍一维全息理论以简化超表面设计。通过这种方式，与传统的二维对流天线相比，整体结构具有更少的晶胞，更简单的结构以及波束倾斜。同时，为了有效地馈入上方的超表面，通过添加倾斜的金属条作为平面波表面波发射器来修改锥形微带线，从而获得从准横向电磁波到横向电磁波的平滑过渡，并获得宽频带阻抗匹配。最后制造并测试了原型。在16 GHz处测得的辐射束角为49°，近似于预先需要的值。另一方面，该天线天线在13至17.5 GHz范围内的波束扫描角为24°至63°。在上述频率范围内，增益约为13至15 dBi，半功率波束宽度约为9°。它具有稳定的高增益，窄的波束宽度和高的辐射效率的特点。
