Abstract

We present a circular patch antenna that has been miniaturized by use of a magneto-dielectric substrate composed of an array of barium strontium titanate (BST) cubes embedded in Teflon substrate. The patch diameter was reduced by 4.5 times when compared to a traditional λ/2 patch antenna radiating at the same frequency but without the magneto-dielectric substrate. Experimental results agree well with simulations and show that if matched well, the antenna can exhibit two peak gains of 7 dB and 2.7 dB at 2.347 GHz and 2.377 GHz respectively. The antenna radiates with an efficiency of 45 % at 2.435 GHz.
