Abstract

In this paper, we present a single feed circularly polarized microstrip patch antenna operating at 2.4 GHz WLAN frequency. A typical microstrip patch antenna is fabricated on a metal coated dielectric substrate where the metallic antenna patch is defined on the top of the substrate, whereas the bottom of the substrate acts as a ground plate. These antennas are typically used for civil and military communication purposes. Before fabrication, the presented antenna was first designed, simulated and optimized in CST Microwave studio. The circular polarization was achieved by perturbation of the edges, making the design optimization a bit challenging. The simulated and measured return loss of the proposed antenna is -27 dB and -13.34dB, respectively. Whereas, the gain came out to be 6 dB. The obtained results show that the presented antenna has the quality of right hand circular polarized antenna. 
2.4GHz右旋圆极化微带贴片天线的设计与制作
本文提出了一种工作在2.4GHz无线局域网频率下的单馈圆极化微带贴片天线。典型的微带贴片天线是在金属涂层的电介质基板上制造的,其中金属天线贴片被定义在基板的顶部,而基板的底部充当接地板。这些天线通常用于民用和军用通信目的。在制造之前,所提出的天线首先在CST微波工作室进行了设计、模拟和优化。圆偏振是通过边缘的扰动来实现的,这使得设计优化有点具有挑战性。模拟和测量的回波损耗分别为-27dB和-13.34dB。然而,增益为6dB。结果表明,该天线具有右旋圆极化天线的性能。
