Abstract

ABSTRACT This article presents a circular microstrip patch antenna loaded with three complementary split rings (CSRRs) on the ground plane for pattern agility features. The antenna resonated at 5.3 GHz and accommodated the frequency spectrum from 5.1–5.7 GHz for different CSRR combinations. The reconfigurable pattern feature has been produced with three p-i-n diode combinations integrated with the CSRR slot on the ground patch. The CSRR combinations are utilized to change the radiation phase concerning the primary radiating circular patch. The proposed antenna radiation beam can steer from ±15°, 180°, and 0° of the broadside pattern in the elevation plane with a satisfactory gain of 3 dBi. The phase variation for various CSRR combinations concerning the primary antenna is presented. The presented antenna is fabricated on an FR4 substrate and tested in an anechoic environment; the tested results verify the pattern agility of the antenna. The demonstrated antenna is suitable for modern wireless communications like LTE and Cognitive radios. The compact size, simple biasing, and low cost are added advantages of the antenna.

用于现代无线通信系统的新型模式敏捷微带天线

摘要本文提出了一种圆形微带贴片天线，该天线在地平面上加载了三个互补的开口环（CSRR），具有方向图灵活性。天线的谐振频率为5.3 GHz，并适应5.1–5.7的频谱 GHz，用于不同的CSRR组合。可重构图案特征是用三个p-i-n二极管组合与接地片上的CSRR槽集成而成的。CSRR组合用于改变与主辐射圆形贴片有关的辐射相位。所提出的天线辐射波束可以在仰角平面中从宽侧方向图的±15°、180°和0°转向，增益为3dBi。给出了与主天线有关的各种CSRR组合的相位变化。所提出的天线是在FR4基板上制造的，并在消声环境中进行了测试；测试结果验证了天线的方向图灵活性。演示的天线适用于LTE和认知无线电等现代无线通信。紧凑的尺寸、简单的偏置和低成本是天线的附加优点。
