| Abstract: | The circular polarisation diversity with the square patch microstrip antenna was obtained by the implantation of the quadrature hybrid as a microstrip feed line. The small size antenna is achieved by using the aperture coupled structure. The cavity model has been used to design an aperture coupled microstrip antenna (ACMSA) and determine the length of the open microstrip stub line in order to match microstrip antenna. The MATLAB and Advanced Design Software (ADS) have been used for designing and simulating the ACMSA. There is a good agreement between the simulated and the experimental results. |
