A reconfigurable antenna for frequency diversity controlled by PIN diode

Amel Boufrioua

Abstract


The design of a reconfigurable antenna with switchable slot is proposed in this paper, slot is etched on the rectangular patch and PIN diode is used to switch the slot in ON and OFF states, the patch is fed by a probe coaxial (50Ω), this type of antenna allows us to have multiple frequencies, the results in terms of return loss and radiation pattern are given. It is observed that frequency diversity can obtained by controlling the bias voltage with unchanged antenna, unchanged feeding probe and unchanged geometric shape of the patch, the thing that was not previously feasible of the unslotted patch antenna.
