Abstract :
A new dual band dielectric resonator antenna (DRA) for WLAN band is presented. The DRA is excited by a vertical strip attached to the DRA, which is connected to a 50 Ω microstrip line on a defected ground plane. The deformed ground plane has a conducting strip under the DRA that cause the first resonance at 2.4 GHz. The second band is wide with 44% bandwidth between 5 to 8 GHz due to the dielectric resonator and the vertical strip excitation.
