Abstract

Magneto-dielectric substrates with thin magnetic films show great potential in realizing electrically small antennas with enhanced bandwidth, improved directivity, and high efficiency. This is the first time to introduce 10-μm thick self-biased NiCo-ferrite films as a practical means to tune a patch antenna by loading Ferrite/Rogers/Ferrite (F/R/F) sandwich structures. The central resonant frequency of the base line patch antenna with composite of Rogers and alumina substrate is 2460MHz with a bandwidth of 42MHz. However, with F/R/F loading of the alumina substrate, this frequency is down shifted to 2380 MHz with a greatly improved bandwidth of 74MHz. In addition, the gain of the magnetic antenna with F/R/F sandwich structure is enhanced by 2.4dB over the unloaded antenna.
