Rectangular Microstrip Patch Antenna Using Coaxial Probe Feeding Technique for 5.2 GHz WLAN Application [ ]


In this paper, the design of a co-axial fed single layer microstrip patch antenna for 5.2 GHz WLAN application is presented. The radiation characteristics of this proposed structure are studied and analyzed using “CST Microwave studio V14”, which is a commercially available electromagnetic simulator based on the method of finite difference time domain technique to achieve the desired specification. This antenna, based on a thickness of 2.4 mm Flame Retardant 4 (FR-4) substrate with a dielectric constant of approximately 4.3.The proposed antenna based on co-axial feed configuration has the maximum achievable bandwidth obtained about 350.2MHz (5.0408-5.391 GHz) at -10 dB reflection coefficient and the maximum achievable gain is 4.72 dB.
