Compact Y-shaped Broadband Planar Antenna for WBAN Applications

Abstract

A compact Y - Shaped antenna with a defected ground structure for Wireless Body Area Network is presented and is operating in the terahertz frequency range. This antenna is having an impedance bandwidth of 10.519 THz (1.147 THz-11.66 THz) and a microstrip feed line is employed to feed the antenna. By making amendments in patch shape and causing defects in the ground, size reduction of the antenna and substantial enhancement in bandwidth are reached. The antenna is radiating at 2.515 THz, 3.872 THz, 7.287 THz, and 10.084 THz respectively. To get the desired result parametric investigation is conducted and the results are described methodically. The maximal gain of the antenna is 15.07 dB at 7.716 THz.
