摘要

本文提出了一种基于互补劈裂环谐振器(CSRR)为主辐射体的小型化印刷微带天线设计方案。该天线由一对蚀刻在地平面上的CSRRs组成,并由对称放置在上基板侧的两个CSRRs之间的开放式微带馈线激励。增强csrs固有的有限带宽;在每个CSRR附近引入两个矩形槽,从而显著提高了带宽,也降低了工作频率。天线的谐振频率基本上由CSRR的几何参数定义,这使得它适用于从移动终端到WLAN和WPAN系统的广泛应用。利用CST微波工作室对该结构进行了数值研究。

New Design of Compact CSRR Antenna Loaded with Rectangular Slots
In this paper, we present a new design of miniaturized printed microstrip antenna based on Complementary Split ring resonators (CSRR) as main radiators. The antenna is composed of a pair of CSRRs etched on the ground plane and excited by an open-ended microstrip line feed symmetrically placed between the two CSRRs at the upper substrate side. To enhance the inherently CSRRs limited bandwidth; two rectangular slots are introduced in the vicinity of each CSRR resulting in a significant bandwidth improvement and also in lowering the operating frequency. The resonance frequency of the antenna is essentially defined by geometrical parameters of the CSRR, which makes it suitable for a broad range of applications spanning from mobile terminals to WLAN and WPAN systems. The proposed structure has been studied numerically by using CST Microwave studio.
