  Abstract

In this paper, a novel Snowflake-shaped microstrip patch antenna for application in the WLAN(5.2/5.8GHz) band is designed and fabricated. The size of antenna is 21.2×16mm² and substrate is used Taconic-RF30. To obtain sufficient bandwidth in Return loss <-10dB and dual resonance characteristic, the Short-pin is inserted on the patch and the coaxial probe source is used. The measured results of fabricated antenna show 220MHz and 135MHz bandwidth in Return loss <-10dB referenced to the WLAN(5.2/5.8GHz) band. The measured antenna gain is 4.7~6.9dBi in the WLAN(5.2/5.8GHz) band. The experimental 3-dB beam width in E-plane and H-plane are 73.2° / 82.75° for 5.150GHz, 74.56° / 83.63° for 5.350GHz, and 86.24° / 85.15° for 5.785GHz, respectively.
