一种新型宽频带多频微带天线设计
Design of a Novel Broadband Multi-frequency Microstrip Antenna
摘要
Abstract
For the fact that there are few designs of multi-frequency antenna suitable for Bluetooth,radio frequency identification(RFID),WiMAX and wireless local area network(WLAN) application simultane-ously,a new miniaturized broadband multi-frequency monopole microstrip antenna is proposed. The pro-posed antenna mainly consists of a rectangular ring,a hexagonal ring with a gap,three rectangular strips and a defected ground plane ( DGP ) . The proposed antenna can excite three separate impedance band-widths to cover all the 2 . 4/5 . 2/5 . 8 GHz Bluetooth/WLAN/RFID operating bands and the 2 . 5/3 . 5/5 . 5 GHz WiMAX bands. It provides three impedance bandwidths of 0. 11 GHz,0. 86 GHz and 1. 11 GHz for the working bands of 2. 38 ~2. 49 GHz centered at 2. 47 GHz,3. 19 ~4. 05 GHz centered at 3. 48 GHz and 4. 95~6. 06 GHz centered at 5. 55 GHz,respectively. Furthermore,the 5. 75 dBi of relative high gain is achieved. A prototype is experimentally tested,and the measured results show its good radiation patterns and enough gains across the operation bands. It can be applied in present wireless communication system.关键词
