Abstract :
A novel method of reconfigurable substrate integrated waveguide (SIW) antenna is proposed. By loading ferrite slabs and applying DC magnetic bias, we realize the reconfiguration of operating frequency and polarization of the SIW antenna. The experiments demonstrate the reconfigurable SIW antenna could have broadband frequency tunable range which is up to 14.9% in microwave X-band, and the radiation can transform between circular and linear polarizations. The fabricated antennas have gain over 5 dBi and radiation patterns changes little in tuning.
