Modified Annular Ring Slot Antenna for Dual WLAN Band application

摘要：

In this paper, the modified annular ring slot antenna is proposed for 2.4/5-GHz dual WLAN band operation.The higher order resonant modes in the annular ring slot are used to control the second operating frequency. The proposed antenna is printed on a FR-4 substrate, and has dimensions of 50 × 50 ×1.2 mm with a ground plane. The frequency ratio of the two operating frequencies can be adjusted from 1.97 to 2.64 with geometric values. The measured impedance bandwidths (VSWR<2) of the proposed antenna are approximately 13.2％ for the 2.4-GHz band and 40％ for the 5-GHz band and the peak gains are 3.74, 4.12 and 5.25 dBi for 2.45, 5.35 and 5.8 GHz bands,respectively.
