Novel Design of Multiband Microstrip Patch Antenna for Wireless Communication

摘要

This paper presents a novel six band frequency reconfigurable antenna for 2.4 GHz (Lower Worldwide Interoperability for Microwave Access (WiMAX)), 5.3 GHz (Wireless Local Area Network (WLAN)) and 9.1-10.2 GHz (X-band) frequency bands. The proposed antenna has a compact size of 22mm_30mm at lower resonance of 4.2 GHz and is printed on FR4 material with height h =1.6 mm, loss tangent _= 0.02 and dielectric constant _r=4.4. Multiband phenomenon in the designed antenna is reached by inserting a circular hole inside a rectangular patch antenna and rectangular slots in the ground plane. During simulation, the designed antenna exhibits hexa band with S11-10 dB bandwidth of about 4.76% (4.1- 4.3 GHz), 4.71% (5.21- 5.43 GHz), 16.27% (6.55-7.25 GHz), 1.83% (7.02-7.15 GHz), 0.87% (9.07-9.15 GHz) and 4.90% (10.02- 10.5 GHz) under simulation. We used HFSS (high frequency structured simulator) software for simulation of antennas and to find out the results. We keep changing the design of the antenna, as our objective is to achieve miniature antenna with better performance than traditional one.
