Compact Size and Slotted Patch Antenna for WiMAX and WLAN

Objectives: Dual-Band, reduced size, coaxial fed probe, Inverted C-slot patch antenna for wireless communication is designed in this paper. The excellent dual-band performance is attained by using inverted C-slots on the patch. Methods/Statistical Analysis: The slots provide two notched bands covering 2.7 GHz to 4.04 GHz for WiMAX and 5.32 GHz to 6 GHz for WLAN with excellent return loss and satisfactory VSWR. Findings: Two resonant peaks obtained are at 3.2 GHz and at 5.4 GHz. The proposed antenna size is 29 mm × 29 mm. The antenna has been effectively simulated on HFSS and tested on VNA tool. The peak gain of 4.65 dB and efficiency of 95% is obtained. The antenna presentation is analyzed on the basis of size of antenna, VSWR, bandwidth, return loss and efficiency. The presented antenna is an excellent choice for WLAN and WiMAX. Improvements: As compared to conventional Microstrip Patch Antenna return loss is improved with 67% and area minimization of 63% has been attained.
