Asymmetric coplanar waveguide-fed CRLH-TL based antenna for WLAN/LTE applications
In this paper a novel type of resonant antenna based on asymmetric coplanar wave guide structure has been presented. In the defined geometry bandwidth can be increased by introducing resonator ring in composite right/left handed transmission line model. Efficiency as well as gain of the geometry can be improved by incorporating comb drive type of structure which introduces interdigital capacitors and produces one more resonant frequency. Asymmetric ground plane reduced the dimensions up to 38.5×25 mm. Dual band have been obtained covering impedance bandwidth of (2.34-2.55 GHz), 210 MHz in lower band and (3.2-3.8 GHz),600 MHz in higher band corresponds fractional bandwidth of 8.7% and 16.3%. Antenna geometry is highly efficient showing maximum efficiency of 99% and peak gain up to 4.23dBi. Defined antenna is very suitable for WLAN/LTE applications.
