Abstract


A novel compact dualband patch antenna with microstrip-fed is presented in this paper for wireless communication bands. The proposed antenna has small geometry with dimensions of W×L (20×30 mm2) and printed on commercially available FR-4 substrate. The basic radiating element of antenna is rectangular shape patch, which is printed on the top layer of the substrate. Radiating patch is exited by 50 Ω microstrip line. Ground plane is located on the bottom side of the substrate which is made defective by etching two T- shaped slots. This antenna yields two resonance frequency bands centred at 3.56 GHz and 5.11 GHz. The simulated -10 dB return loss shows that bandwidth for lower frequency band is 13.4% (3.28-3.76 GHz) and for upper frequency band is 10.7% (4.86-5.41 GHz). This prototype is well suitable for WiMAX and WLAN wireless applications. To understand the effect of the parameters on antenna performance a parametric study is also carried out.
