Rectangular Micro Strip Patch Array Antenna With Corporate Feed Network For Wireless Communication Applications

Nowadays the wireless communication system development requires the low cost, low profile; minimal weight antenna development which is accomplished of continuing great presentation completed a wide frequency range. This upcoming technology fashion has motivated the MSPA (Microstrip Patch Antenna) design. This paperwork presents design and analysis of 2 patches (2 by 1) and 4 patches (4 by 1) Rectangular Microstrip Patch Array (RMSPA) Antennas with corporate feed network systems for S band applications at 2.45 GHz. This S band frequency range is mostly used for mobile satellite communication systems an also used in Bluetooth, Zigbee, Wi-Fi communication technologies. In the proposed work, 4.5 dielectric constant and 1.65 mm thickness of the substrate is used. The primary of this research work is to present an RMSPA antenna design and analysis using CSTMWS software “Computer Simulation Technology Micro Wave Studio” and investigate the performance of 2 elements patch arrays with that of a 4 elements patch arrays for the same 2.45 GHz operating frequency. It also made the study and investigation between the 2 elements and 4 elements corporate feed systems in terms of reflection coefficient (return loss), VSWR, bandwidth, directivity, gain, and radiation pattern. The main intension of this paperwork is to achieve an extraordinary directivity with enhanced gain and reduced losses at S band frequency range.
