Analysis of a Disc-Shaped Monopole Antenna for RF Energy Harvesting in 1.71-12GHz

Abstract

The specified script gives the description of a disc-shaped monopole for RF power harvesting within many popular bands starting from GSM1800 uplink frequency 1.71 GHz to X Band. The specified antenna senses the wasteful RF power in those bands. The FR4 material of size 42×32×1.6mm3 is chosen as substrate for prototype model. It records impedance bandwidth range 1.71GHz-12.11GHz. The radiation efficiency is highest at 1.71GHz., and peak gain is highest at 9.67GHz. They are recorded as 97%, and 5dBi respectively. The description of fractional grounds with embedded slots is given. This monopole is simulated by HFSS. The prototype model S11 concurs well with simulated design.
