Design of e-shaped dielectric resonator antenna for ultra wideband (UWB) applications

Srivastava, Chandan and Gaihre, Arjun (2013) Design of e-shaped dielectric resonator antenna for ultra wideband (UWB) applications. BTech thesis.



Past few decades have witnessed huge advancements in the field of Antennas in terms of size, cost, efficiency, bandwidth, losses, power handling capacity and gain. Dielectric Resonator Antenna (DRA) is very latest and very efficient technology in the field of Antennas. It is very small in size, larger bandwidth, low losses, lower cost and very easy to integrate with existing technology. Here an E-shape DRA for Ultra-Wide Band (UWB) application is presented. It is very small in size. Antenna size is 24x24 mm2. We have used a substrate of size 24x24x1.6 mm3 with a 4.4 dielectric constant. We have used a ground plane of size 24x10 mm2. E-shape dielectric that has been used dielectric constant 2.1 and its height is 3 mm. Microstrip line is used as feeding line with dimensions 3x15 mm2. This antenna works best in frequency range of 6.7995-10.933 GHz. Its resonant frequency is 7.6818 GHz. VSWR parameter should be less than 2 within operating frequency range. This can be used in short range tracking, missile guidance, marine radar etc. as it comes mostly in X-band for UWB.
