“…For example, a reconfigurable antenna can be designed to shift the beam in the desired direction, place a null in a certain direction to reduce interference, change the resonance frequency or change the polarization from linear to circular. Recently, reconfigurable dielectric resonator antennas have been presented in the literature for frequency control [21], [22], and [24]. A rectangular DRA that is able to switch between two different frequencies, 4.12 GHz and 8.85 GHz, is introduced in [24].…”

A rectangular DRA that is able to switch between two different frequencies, 4.12 GHz and 8.85 GHz, is introduced in [24]. This reconfigurable dielectric resonator antenna works in different bands by setting the switch on the connecting lines of a network that feeds the dielectric element and changing the state of switch from ON to OFF, a shift of the well-matched operating frequency range is obtained.…”

A novel reconfigurable dielectric resonator antenna (DRA) employed a T-Shaped microstrip-fed structure in order to excite the dielectric resonator is presented. By carefully adjusting the location of the inverted U-shaped slot, switches, and length of arms, the proposed antenna can support WLAN wireless system. In addition, the presented DRA can be proper for cognitive radio because of availability switching between wideband and narrowband operation. The proposed reconfigurable DRA consisting of a Roger substrate with relative permittivity 3 and a size of 20 mm × 30 mm × 0.75 mm and a dielectric resonator (DR) with a thickness of 9 mm and the overall size of 18 mm × 18 mm. Moreover, the antenna has been fabricated and tested, which test results have enjoyed a good agreement with the simulated results. As well as this, the measured and simulated results show the reconfigurability that the proposed DRA provides a dual-mode operation and also three different resonance frequencies as a result of switching the place of arms.
