摘要

提出了一种二维周期蘑菇结构的锥形波束漏波天线。据作者所知，这是第一个实验证明的二维漏波天线。该结构可以建模为复合右/左(CRLH)传输线，并表现出向后和向前泄漏。显示了天线的辐射方向图，并证明了扫描范围为15/声级角/-33/声级角/在后向区域和27/声级角/-63/声级角/在正向区域。

Leaky-waves in a metamaterial-based two-dimensional structure for a conical beam antenna application

A two-dimensional periodic mushroom structure is proposed as a leaky-wave antenna with a conical beam. To the author's knowledge, this is the first 2D leaky wave antenna demonstrated experimentally. The structure can be modelled as a composite right/left-handed (CRLH) transmission line and exhibits both backward and forward leakage. The radiation patterns for the antenna are shown and demonstrated a scanning range of 15/spl deg/-33/spl deg/ in the backward region and 27/spl deg/-63/spl deg/ in the forward region.
