A simple coplanar structure antenna for 4G mobile handset

In this article, a simple coplanar structure antenna for 4G handset is presented and verified with experimental results. The presented antenna can be easily printed on the no-ground area of the top of a FR4 substrate with dimensions of 43×20mm2. Based on the 6-dB return loss, the four operating bands can be employed in LTE 700/LTE 2300//LTE 2500/LTE 3500 applications. Good radiation efficiency and antenna gain for frequencies over the desired operating bands is obtained. The measured data show good agreement with the simulation. The study indicates that the proposed antenna is good candidate owing to its wide impedance bandwidth, simple structure, low cost and ease of construction, with a good prospect of the 4G handset application.
