【 摘 要 】

This letter presents frequency-reconfigurable microstrip patch antenna with three switchable modes. Two RF p-i-n diodes are positioned between inner and outer patches to achieve frequency reconfigurability. Six parasitic patches are added to the antenna; therefore, gain and bandwidth are noticeably increased. The results indicate that the highest achieved bandwidth and gain are 90 MHz and 3.4 dBi, respectively. The return loss, together with the radiation patterns, are presented.
