Abstract :
A theoretical analysis of circular microstrip antenna on a ferrimagnetic substrate predicts significantly reduced resonant radii and improved bandwidth as compared to those of similar antennas built on purely dielectric substrates, when operated in the lower range of UHF. The impedance characteristics, return loss, and radiation pattern studied experimentally for antennas built upon a typical ferrite substrate are found to be in good agreement qualitatively with the theoretical results.
