摘要：
A compact dual-hand rectangular ring printed antenna for wireless local area network (WLAN) applications is proposed and investigated in this paper. The dual-band is realized by using a rectangular ring patch connected with a 50 Omega mini-coaxial feed structure composed of a longitudinal slot and a small rectangular, occupying a small board space of 30.6mm*6mm on the system circuit hoard. With a modified rectangular ground plane on the hack of the main structure, a better impedance matching is obtained. The antenna provides two wide operation hands covering the WLAN frequency bands: 2.4GHz(2.4-2.483GHz),5.2GHz(5.15-5.35GHz)and 5.8GHz(5.725-5.875GHz) applying to IEEE 802.11a and IEEE 802.11b. This antenna is simulated and studied by the High-Frequency Structure Simulator (HFSS) and the operating procedure of the proposed antenna is described in detail, as well. The result of simulation reveals that the resonant hands are 2.2166Hz to 2.612GHz and 5.108GHz to 5.875GHz with the relative bandwidth of 16.2% and 13.2% respectively. Besides, the fabricated antenna is tested by the vector network analyzer, and the results are in accordance with the simulated on the whole.
