Frequency Tunable Monopole Patch Antenna Using Broadside Coupled Split Ring Resonator for Wireless Communication Applications

This paper presents metamaterial based monopole patch antenna capable of tuning the radiating frequency over a wide bandwidth. The proposed novel antenna structure makes use of the metamaterial properties of Broadside Coupled Split Ring Resonator (BCSRR) for frequency tuning. The magnetic resonant frequency of the proposed antenna can be tuned by slightly adjusting the interplanar distance between the rings of the BCSRR so that the coupling due to effective capacitance and inductance between them can be changed. The desired range of frequency tuning for potential applications like Global System for Mobiles (GSM), Bluetooth, Wi-Fi, Wi-Max, WLAN etc. is achieved by proper designing of the geometrical parameters of BCSRR. The different antennas for different applications in a single device can be replaced with the proposed novel metamaterial based antenna structure.
