Flower shaped antenna for terahertz applications

Abstract

Flower shaped antenna along with a rectangular resonator is reported in this paper for THz applications. The dimension of antenna is 20×30×1.6 mm3. FR4 material is used as substrate. Return loss, radiation pattern and gain of the antenna are presented and analyzed to study the performance of the antenna for THz applications. The frequency band is obtained at 0.92 THz with the impedance bandwidth of 710 GHz. The peak gain of this antenna is obtained as 12.786 dB at 1.01 THz.
