Hybrid HMSIW Cavities Antenna With a Half-Pentagon Ring Slot for Bandwidth Enhancement
A substrate-integrated waveguide (SIW) antenna is an implementation of a waveguide antenna in a microstrip antenna.The microstrip antenna, as a low-profile antenna, suffers from narrow impedance solace nicotine salts bandwidth.This paper proposes a novel bandwidth enhancement method for solving a narrow impedance bandwidth.Bandwidth enhancement was
