Abstract
In this paper, a frequency-tunable patch antenna printed on a dielectric-magnetic composite substrate is presented. The antenna substrate is constructed using duriod dielectric with ferrite slabs embedded into the substrate. Split-ring resonators (SRR) are integrated into the magnetized ferrite slabs to achieve frequency-reconfigurable properties. The constructive coupling between the resonances of the magnetized ferrites and SRR is optimized to achieve a better tuning range by minimizing the required external magnetic field needed to magnetize the ferrite. The frequency tuning range of the proposed frequency reconfigurable antenna is improved, and a 670 MHz range has been achieved. The antenna exhibits a very good gain of 7.1 dB and an efficiency of 77%, and the experimental results corroborate the simulation results.
