Analysis Of Rectangular Resonant Microstrip Antenna Loaded With Metamaterial And A Slot Loaded Rectangular Microstrip Antenna

Abstract

Authors analyze a slot loaded rectangular micro-strip patch antenna and a sub-wavelength compact, resonant patch antenna loaded with metamaterial. The slot is taken as capacitive reactance on the patch.  It is found that the resonance frequency  decreases with increasing slot width for a given slot length the decrease in the resonance frequency in the lighter side for longer slot length, where as it is in the min. side for the lower slot length, in case of resonant patch antenna loaded with metamaterial  the matching and radiation properties have analyzed. It is shown how these configurations may exhibit in principle an arbitrarily low resonant frequency for a fixed dimension, but they may necessarily radiate efficiently when their size is electrically small.
