Abstract

A novel reconfigurable circular microstrip G-slotted antenna having a circularly defected ground structure (DGS) capable of switching its resonance frequency for several microwave applications is presented in this paper. Reconfigurability of the proposed G-slot antenna is obtained by incorporating three PIN diodes. One diode is embedded in the patch and two diodes are integrated into the DGS structure at appropriate places in the slot to achieve four different wireless applications such as aeronautical radio navigation (4.3 GHz with gain 3.6 dB), satellite communication (3.78 GHz with gain 3.7 dB), mobile communication (4.55 GHz with gain 4.0 dB), and WiMAX (3.35 GHz with gain 3.3 dB). These four bands are achieved depending on the different biasing conditions of the three PIN switches used. Antenna performance has been analyzed in ANSYS Electronics Desktop 2018.2 software. The equivalent circuit component of the switching element (PIN diode) has been considered and designed during the simulation. The creative structure lies in the way that it exhibits higher gain with compact size than the previously reported similar antenna. A prototype of the proposed patch antenna has been fabricated on a Roger substrate and its testing and measurement have been performed to demonstrate its desirable characteristics and features.

带 DGS 的频率可重构圆形微带 G 槽天线，适用于各种无线应用

本文介绍了一种新型可重构圆形微带 G 槽天线，该天线具有圆形缺陷接地结构 (DGS)，能够切换其谐振频率，适用于多种微波应用。拟议的 G 形槽天线的可重构性是通过集成三个 PIN 二极管实现的。其中一个二极管嵌入贴片中，两个二极管集成在 DGS 结构中插槽的适当位置，以实现四种不同的无线应用，如航空无线电导航（4.3 GHz，增益 3.6 dB）、卫星通信（3.78 GHz，增益 3.7 dB）、移动通信（4.55 GHz，增益 4.0 dB）和 WiMAX（3.35 GHz，增益 3.3 dB）。这四个频段的实现取决于所用三个 PIN 开关的不同偏置条件。天线性能在 ANSYS Electronics Desktop 2018.2 软件中进行了分析。仿真过程中考虑并设计了开关元件（PIN 二极管）的等效电路元件。与之前报道的类似天线相比，其创造性的结构在于以紧凑的尺寸表现出更高的增益。已在 Roger 衬底上制作了拟议贴片天线的原型，并对其进行了测试和测量，以证明其理想的特性和功能。
