“…During the last three decades, antennas using highpermittivity dielectric materials as a radiation element have taken extensive attention due to advantageous properties such as ease of excitation, small size, high radiation efficiency, suitable scale in microwave bands and various DR shapes [1][2][3]. There are various excitation mechanisms that can be used to excite DRs such as coaxial probe [4], microstrip feed lines [5], and coplanar waveguides (CPWs) [6].…”

A compact frequency reconfigurable dielectric resonator antenna (DRA) for LTE/WWAN and WLAN applications is investigated and presented. The proposed antenna provides the frequency tuning between 1.60 GHz and 2.71 GHz. The design consists of four identical rectangular dielectric resonators with permittivity of 10 each and three PIN diode switches which are located on the feed line network between each two dielectric resonators. The proposed antenna size is 20 × 36 × 5.57 mm3 that is suitable for mobile devices. The measurement and simulation results are applied to demonstrate the performance of the proposed antenna. From the measured results, it is found that the proposed antenna with acceptable performance provides four single band modes with the impedance bandwidth of 17%, 11%, 14 % and 6%. Index Terms-Dielectric resonator antenna (DRA), reconfigurable antenna, PIN diode.

“…The higher efficiency in DRA is due to the lack of conductor loss . Additionally, several types of feed mechanisms can be applied to excite dielectric resonator (DR) antennas such as coaxial probe , microstrip feed lines , coplanar waveguides (CPWs) , and aperture . However, designing multiband DR antennas to cover most required applications is still big challenge due to needing more than one antenna or achieving with large size antenna.…”

A CPW‐fed frequency reconfigurable dielectric resonator antenna (DRA) is studied and presented for WiMAX and wireless local area network applications. The frequency tunable DRA is able to alter the frequency at three different dual bands frequency. The rectangular dielectric resonator has a permittivity of 10. Two PIN diode switches are located on the connecting lines of the network, which feeds the three dielectric resonator elements. Three dual‐band modes with center frequency of 2.4 and 5 GHz in ON–ON state, 2.5 and 5.2 GHz in OFF–ON state, 3.5 and 5.8 GHz in ON–OFF state by switching of the diodes are achieved. The proposed dielectric resonator (DR) antenna has a compact size of 33 × 45 mm2 with a DR thickness of 2.8 mm. the simulation and measurement results are compared to prove the good agreement and performance of the proposed antenna. © 2015 Wiley Periodicals, Inc.
