摘要

本文研究了一种设计工作频率为2.536 GHz的快速充电图标型缝隙天线(FCISA)。该天线覆盖2.389 GHz ～ 2.6968 GHz频段，适用于2.45 GHz蓝牙(2.407 GHz ～ 2.484 GHz)、2.4 GHz Wi-Fi (2.407 GHz ～ 2.484 GHz)、WiMAX rel 1 (2.3 GHz ～ 2.40 GHz)和WiMAX rel 1.5 (2.5 GHz ～ 2.69 GHz)。天线的整体尺寸为$40\times 38\times 0.79mm^{3}$，蚀刻在罗杰斯RT 5880上($\varepsilon_{r}$ =2.2, $\delta$ = 0.0009)。天线的最大增益为3.16 dB，最大指向性为3.51 dBi。该天线的反射系数为-40.699dB，驻波比为1.0186，工作频率为2.536 GHz。快速充电图标型槽天线的辐射效率始终在90以上%. Thus the antenna is quite appropriate for Bluetooth, Wi-Fi and WiMAX applications.

A Fast Charging Icon-shaped Slotted Patch Antenna for Bluetooth/Wi-Fi/WiMAX Applications

This paper deals with a fast charging icon-shaped slotted antenna (FCISA) which is designed to operate at 2.536 GHz. This antenna covers the frequency band from 2.389 GHz to 2.6968 GHz which is applicable for 2.45 GHz Bluetooth (2.407 GHz to 2.484 GHz), 2.4 GHz Wi-Fi (2.407 GHz to 2.484 GHz), WiMAX rel 1 (2.3 GHz to 2.40 GHz) and WiMAX rel 1.5 (2.5 GHz to 2.69 GHz). The overall dimension of the antenna is $40\times 38\times 0.79mm^{3}$ which etched on Rogers RT 5880 ($\varepsilon_{r}$=2.2, $\delta$= 0.0009). The maximum gain and directivity of the antenna are 3.16 dB and 3.51 dBi respectively. The reflection coefficient of this antenna is -40.699dB with approximately unity VSWR (1.0186) which operates at a resonant frequency of 2.536 GHz. The radiation efficiency of the fast charging icon-shaped slotted antenna is always above 90%. Thus the antenna is quite appropriate for Bluetooth, Wi-Fi and WiMAX applications.
