Design and Simulation of Quadratic Curve Discone Antenna for Medical Interference

Discone antenna is one of sensor types suitable for measuring electromagnetic interference (EMI) that occurs on its broadband characteristics. In this paper, the development of discone antenna is proposed for EMI measurement of medical device. The proposed discone antenna is designed by modifying the cone part of the antenna to be the quadratic curve shape. The simulation results show that the greater the curvature degree of quadrature curve shape, the lower the reflection coefficient

value and the higher the cut-off frequency.
