Abstract

Gain enhancement wideband end-fire antenna is proposed in this paper. The proposed antenna can achieve gain enhancement by loading novel artificial materials structures (Split-ring Resonators) in the end-fire direction while broad bandwidth is realized by using elliptic dipole elements and a microstrip to coplanar balun. The measurements show that the proposed antenna have around 5-8 dB gain in the working band (5-11 GHz), which is around 2 dB more than the unloaded one. This antenna can be used in target recognition systems for its advantages of end-fire radiation broad bandwidth and high gain.

摘要

本文提出了一种增益增强型宽带端射天线。所提出的天线通过在端射方向加载新型人工材料结构（分裂环谐振器）来实现增益增强，同时通过使用椭圆偶极子元件和微带 - 共面巴伦来实现宽带宽。测量结果表明，所提出的天线在工作频段（5 - 11GHz）具有约5 - 8dB的增益，比未加载的天线高出约2dB。该天线因其端射辐射、宽带宽和高增益的优点可用于目标识别系统。
