Abstract :
In this paper, a new method for broadening of impedance bandwidth of rectangular dielectric resonator antenna (DRA) has been demonstrated. In the proposed configuration, two adjacent resonant modes were excited by the additional L-shape feed-line. For the suggested optimum feed network, the impedance bandwidth of over than 11% and 24.5% (for S11 > 10 dB) are obtained in two separate frequency bands at 5-8 GHz.
