Abstract

A compact microstrip feed triple band circular monopole antenna operating over GSM (1.78-1.82 GHz), Bluetooth (2.4-2.48 GHz) and Ultra wideband (UWB: 3.1-10.6GHz) frequency bands is designed and investigated for wireless applications. The UWB frequency operation is achieved by a modified circular radiating monopole with destructive ground plane. Further, by slotting the central portion of the radiating patch and then etching a half wavelength circular arc from the radiating patch a dual band frequency operation over Bluetooth and UWB band is achieved. The triple band frequency operation is realized by embedding quarter wavelength parasitic element/strip resonating at 1.8 GHz placed at the slotted central position in the radiating patch. The proposed antenna is simulated using electromagnetic simulation software CAD FEKO suite (6.3). The proposed antenna is realized on FR-4 dielectric substrate having a dielectric constant of 4.4 and loss tangent of 0.02. The antenna covers the three bands of operation i.e. GSM (1800MHz), Bluetooth (2.4-2.48GHz) and UWB (3.1-10.6 GHz) with reflection coefficient <; -10dB. The antenna also exhibits stable radiation patterns for the entire UWB & aforementioned integrated lower frequency bands.

用于无线应用的集成GSM和蓝牙超宽带印刷单极天线(UWB)的设计

设计并研究了一种适用于GSM (1.78-1.82 GHz)、蓝牙(2.4-2.48 GHz)和超宽带(UWB: 3.1-10.6GHz)频段的紧凑型微带馈电三波段圆单极天线。超宽带频率工作是通过带有破坏性地平面的改进圆形辐射单极子来实现的。此外，通过开槽辐射贴片的中心部分，然后从辐射贴片蚀刻半波长圆弧，实现了蓝牙和UWB频段上的双频段频率操作。通过在辐射贴片的中心开槽位置嵌入谐振频率为1.8 GHz的四分之一波长寄生元件/条带，实现了三频段的频率工作。采用电磁仿真软件CAD FEKO套件(6.3)对天线进行了仿真。该天线在介电常数为4.4、损耗正切为0.02的FR-4介电基片上实现。天线覆盖GSM (1800MHz)、蓝牙(2.4-2.48GHz)和超宽带(3.1-10.6 GHz)三个频段，反射系数<;-10分贝。天线也显示稳定的辐射模式，整个UWB和上述集成的较低频段。
