Abstract

In this paper the A-shape dielectric resonator antenna is modified for circular polarization in low frequencies of wireless applications. In order to have a wide bandwidth, a dielectric with low permittivity is employed. Another dielectric resonator owning a high permittivity is stacked to the other one, which is assigned to provide circular polarization. A Pshape parasitic strip is embedded between the two resonators to guide electrical and magnetic fields for a low axial ratio (AR) over a wide bandwidth. The proposed DRA with good radiation characteristics offers a bandwidth of 34% between 2.90 GHz and 4.11 GHz and an axial ratio of 18%between 3.40 GHz and 4.04GHz for the first band and a bandwidth of 18% between 5.16 GHz and 6.16 GHz for the second band that all support 2.4 GHz Bluetooth, WLAN, 3.3-3.6 GHz (WiMax), 3.8-4.1 GHz (C-band), 4.8-6.2 GHz (5.2, 5.5 & 5.8 GHz-WLAN & WiMax) © 2011 IEEE.
