One wideband coplanar waveguide-fed balanced dipole antenna design

A new compact wideband Coplanar Waveguide (CPW)-fed balanced printed dipole antenna combining multiple symmetric loops and One novel balun DC ground structure, is presented here. This antenna is capable of generating several resonant modes to cover a wide frequency band including CDMA/GSM1800/1900/Wifi/Bluetooth bands. Experimental results demonstrate that the proposed CPW-fed dipole antenna can operate at a wide frequency band from 1710 MHz to 2700 MHz in which the return loss is better than 14 dB. The proposed antenna has a high gain ranging from 2.5 to 3.0 dBi. The proposed antenna utilizes a simple planar compact structure and occupies a small area of only 70.5×30.5 mm2. Details of the antenna design and experimental results are presented and discussed. Therefore, the proposed antenna is very suitable to various applications for high-performance receiving and transmitting. © 2020 International Information and Engineering Technology Association.
