“…Several electronic devices, such as microelectromechanical system (MEMS) switches, field effect transistors, or PIN diodes can be hired to achieve discrete frequency tuning agility. However, the use of MEMS switches in commercial applications deals with some problem such as their questionable reliability, expensive device and require high DC actuation voltage as well as biasing lines . The PIN diode switch is selected for this design because of several reasons: these devices are easy to achieve; they are inexpensive, that is noteworthy in mobile wireless applications; they have small size compared to their operating wavelengths; they result in properly low loss and good isolation; and they have high switching speed and also low package parasitic reactance.…”

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.
