Compact Planar Dual Band Antenna for WLAN Application

A miniaturized dual-band microstrip antenna has been designed and analyzed for Wireless LAN application. The proposed antenna comprises a 29 × 29 mm2 radiating patch, fed by a microstrip line on a 1.6 mm thick FR4 dielectric material substrate. The antenna measurement illustrates impedance bandwidth of around 10% at 2.4 GHz resonance and 6% at 5.5 GHz resonance. The measured stable return loss and radiation patterns are presented for the proposed dual-band electrically small microstrip antenna for wireless applications.
