Abstract
This paper presents a novel compact planar dual-band spurious-free antenna based on metamaterial stepped-impedance resonators. The antenna provides the capability of controlling both of the frequency bands, while ensuring an extended spurious-free stopband. The antenna is designed to operate at UMTS and WLAN frequencies of 2.1 GHz and 2.4 GHz, respectively. The antenna dimensions are only 2 × 2 cm2, which is 50%smaller compared to a conventional half-wavelength patch antenna operating at the same frequencies. Operation mechanism of this antenna will be addressed elsewhere but this paper serves as proof of concept as it illustrates that simulation and measurement results are in close agreement; hence confirming the feasibility of this simple yet efficient antenna.
