| Summary: | A number of slot configurations in the reflectarray patch element designed at 10 GHz are proposed to optimize the design of a reconfigurable refelctarray antenna. It has been demonstrated that the introduction of slots in the patch element can alter the resonant frequency of the reflectarray and hence can be used for frequency tuning of reflectarray antennas. Different types of slot configurations have been employed and dimensions and modifies the surface current distributions on the patch elements and produces a change in the resonant frequency and reflection phase of reflectarray. By varying the dimensions of different slot configurations, a phase change of up to 323.91' and a maximum reflection loss variation of 0.32 dB have been observed. |
