Microstrip Array Antenna

The design and analysis of single double (1×2) and four (1×4) element linear rectangular micro strip array antennas is done to achieve high gain and directivity. The operating frequency of the proposed array antenna is Ka-band, 20.2GHz which is a Beacon frequency of GSAT-14 launched by ISRO.The substrate material used is common for the single, double (1×2) and four (1×4) i.e. FR4 with a thickness of 0.8mm and the dielectric constant is 4.4. The antenna elements are placed uniform at a same distance. The feeding network used here is a parallel or corporate feed network. The power splitting and impedance matching is done using RF Wilkinson power divider. The entire proposed micro strip phased array antenna is evaluated using HFSS software tool.

The present techniques are in the form of open literature used to work on selected frequency that has eight and sixteen rectangular patches. The size of it has become compact. Each approach offers different advantages, depending on the required applications. An array antenna is designed and analyzed using series and corporate feed network The FR4 substrate material which is of low cost and easily available in market is used to design the array antenna. An analysis is carried out for both series and corporate feed array antenna in terms of return loss, peak gain, VSWR, directivity, and bandwidth. The antenna’s size is reduced to a very compact size using optimization techniques without degrading the performance characteristics. The design is implemented to work for the multiband applications rather than a single application. Simulation is carried out in HFSS (High Frequency Structure Simulator) software tool. The design proposed is analyzed based on the performance and then it is fabricated.
