摘要

共形微带天线是微波和通信领域的一个重要研究领域。本文提出了一种适用于多频段DCS/蓝牙/WLAN应用的小型化圆柱共形微带天线(MCCMA)的设计方案。它由一个带六边形槽和几个矩形槽的辐射元件、一个FR4基板、一个同轴馈电和GND组成。小型化特性是通过使用矩形槽来弯曲电流的路径来实现的。仿真和分析表明，该天线具有多频段特性，可以实现天线尺寸的减小。该天线相对于以1.8 GHz为中心的最低工作频率的半径值为$0.13\lambda_{0}$。可覆盖HFSS软件上的1.8 GHz DCS、2.45GHz/5.8GHz WLAN和2.45GHz蓝牙频段。仿真结果表明，该天线具有良好的跨操作辐射方向图，可应用于现有的无线通信系统。

Design of a Novel Multiband Miniaturized Cylindrical Conformal Microstrip Antenna

Conformal microstrip antenna is an important study field in microwave and communications. In this paper, a novel design of miniaturized cylindrical conformal microstrip antenna (MCCMA) for multi-band DCS/Bluetooth/WLAN applications is proposed. It consists of a radiating element with a hexagon slot and several rectangular slots, a FR4 substrate, a coax feeding and GND. The miniaturization characteristic is achieved by using the rectangular slot to bend the path of the current. Simulation and analysis show that the antenna has a multi-band characteristic and can achieve a reduction of the size. A radius value of the antenna is $0.13\lambda_{0}$ with respect to the lowest operating frequency centered at 1.8 GHz. It can cover the 1.8 GHz DCS, 2.45GHz/5.8GHz WLAN and 2.45GHz Bluetooth bands on HFSS Software. The simulated results show that the antenna has good radiation patterns across the operations which can be applied in present wireless communication system.
