dc.description.abstractThe square patch antenna for Global Navigation Satellite System (GNSS) applications has been designed and studied. The antenna designed consists of a square patch with asymmetric comers in order to enhance the performance and improve the radiation pattern. The structure contains a single feed patch antenna which is implemented using the Rogers R04003 substrate. This antenna was designed using a single feed which reduces the cost of antenna. The proposed antenna was designed and simulated using the Computer Simulation Technology (CST) software. A detailed parametric study has been performed in order to better understand the antenna and to optimize each parameter to contribute to the performance. The design was fabricated and tested successfully. Measured results and simulated results of the design are then compared and they are in good agreement. Measured results produced a better gain for the antenna. The objective of this thesis is to analyse, design and fabricate microstrip square patch antenna used in GNSS applications. The measured gain obtained was 5.85 dBic. Return loss obtained in the design was -25 dB. The measured axial ratio < 3dB was obtained in almost all the directions. The axial ratio bandwidth was noted to be about 0.628% with central frequency 1.59 GHz. In conclusion, square patch microstrip antenna with asymmetric comers was designed and studied. The antenna has fulfilled the design specifications suitable for applications in GNSS antennas used in Ll band.en_US
