Novel Compact Monopole Antenna with a Parasitic Plate for WLAN Applications

Wen-Shan Chen, Ho-Yu Lin S. Taiwan Iniversity of Technology

The paper proposed and studied a monopole antenna with a parasitic plate for WLAN applications. In this design, microstripline-fed rectangular patch creates a resonant mode at 3 GHz. Furthermore, a parasitic plate is added on the side of ground plane to generate a dual-band operation of 2.39 to 2.91 GHz and 4.06 to 6.73 GHz.
