A compact dual band directional cylindrical dielectric resonator antenna

A compact dual band cylindrical dielectric resonator antenna (CDRA) is designed and presented. The CDRA is excited by E-shaped aperture, which is located below the microstrip line feed on the ground plane. The defected ground plane has a conducting strip under the Dielectric Resonator Antenna (DRA)...

Beschreibung
Zusammenfassung:A compact dual band cylindrical dielectric resonator antenna (CDRA) is designed and presented. The CDRA is excited by E-shaped aperture, which is located below the microstrip line feed on the ground plane. The defected ground plane has a conducting strip under the Dielectric Resonator Antenna (DRA) that causes the upper resonance at 5 GHz. The lower band at 2.45 GHz is achieved by applying a metallic top-loaded cylindrical dielectric antenna (CDRA). The experimental results show the antenna covers 2.45 GHz and 5 GHz with -10dB return loss, satisfying the desired standards of WLAN applications.
