Design and Optimization of M-Shaped Microstrip Patch Antenna

The proposed antenna is fabricated with substrate RT duroid 5880 and overall patch dimension of 62×64mm. In this paper, we design and implementation of 1x1 microstrip patch antenna array of given specifications using HFSS v15 software. The design have a dielectric material with dielectric substrate permittivity of 2.2 and height of 1.6 mm. The microstrip patch antenna is designed for WLAN and Radio Frequency applications, at an operating frequency of 2.32GHz, 4.78GHz and 8.5GHz with microstrip line feed and power dividers. A new and improved approach for the design of the asymmetric M-shaped patch antenna which works in WLAN and RF application is proposed. Antenna includes of a main patch with sub patches having resonating slots. Main patch is fed with a 50Ω microstrip line and proposed antenna operates with multiple operational frequencies covering the bands from 2GHz to 10GHz with good impedance matching.
