摘要
A novel hybrid resonator consists of right handed patch + composite right and left handed transmission line (RH + CRLH) is proposed for the first time aiming at both compactness and frequency manipulation. A demonstration with theoretical dispersion relations and EM simulation is provided for the correctness and efficiency. According to the new method, an ultra-small and dualband antenna operating around 2.4 GHz (n= 0, Bluetooth band) and 3.5 GHz (n = + 1, Wimax band) is designed, fabricated and measured, whose occupied area is only of 0.158 lambda(0) x 0.08 lambda(0). Numerical and experimental results indicate that the antenna exhibits a good impendence match, low cross-polarization and comparable radiation gains in both bands. Excellent performances of the antennas based on hybrid resonators predict promising applications in multifunction wireless communication systems.
