Abstract

This letter presents the result of the synthesis of a horizontally polarized reconfigurable microstrip antenna. The obtained architecture is based on a parasitic structure composed by a set of microstrip elements that can be electronically reconfigured by means of radiofrequency (RF) switches. As a result, the maximum values and zeros of the antenna radiation pattern can be steered towards an interfering signal or/and desired signals, which allows an optimal management of wireless resources. Representative numerical and experimental results are reported and compared in order to assess the effectiveness and reliability of the proposed prototype.
