Several novel omnidirectional printed dipole antenna units for LTE-FDD/WCDMA system

In this paper several novel wideband omnidirectional printed dipole antenna units whose operating frequency covers 1.92GHz to 2.17GHz(the WCDMA band and the LTE-FDD band 1) based on a basic one(Antenna I) are proposed. Through meandering and slotting on the micro-strip arms, the size of units get less. The experimental results which agree well with the simulation results show that the novel units have good performance on return loss. Indeed, two of them have better radiation patterns than the basic one.
