| Abstract: | The analysis of flush-mounted cylindrical microstrip antennas is presented. The analysis is performed using method of moments in spectral domain, and results are obtained for radiation pattern and input impedance. The results are compared with those obtained for similar geometries, where the dielectric layers extend to infinity. The results show that the housing has not significantly altered the radiation pattern, but the input impedance is affected for small cavity sizes. It is also shown that the resonant frequency diminishes as the superstrate thickness increases. |
