Abstract

Presented is a coplanar waveguide fed antenna for multi-band operation covering the digital video broadcasting signal reception in the UHF band, mobile communications in the GSM band, and the 2.4 GHz 802.11g/n band. The size of the designed antenna is 114×60 mm and it is printed on an FR4 substrate of thickness 0.8 mm with dielectric constant 4.4. It has an inner U-shaped strip enclosed by an outer loop strip and the outer loop strip is designed to obtain a wide operating bandwidth. Experimental results show that the proposed antenna exhibits a good impedance matching over a wide frequency range of 470 to 960 MHz, 1450 to 1880 MHz, and 2.4 to 2.6 GHz.
