Abstract

This study demonstrates the operation of a miniaturized version of a helical antenna array. Axial mode helical antenna was designed with a magnetic film glass composite core. The usual axial mode air core antennas are usually bulky and consume unnecessary space in the applications. This is overcome by the magnetic film core antenna which is basically smaller compared to the traditional mode. This magnetic film antenna has been designed to operate at a frequency of 2.44 GHz. This version has shown 80% reduction in volume compared to the conventional air-core antenna. This particular antenna is used as 2×2 and 4×4 arrays which show a three-fold gain over the single antenna. Therefore, we have achieved high gain along with the miniaturization of the antenna by using the glass core.
