Evaluation of wideband LTE antenna configurations for vehicle applications

An analysis of different configurations of two identical LTE antennas suitable for vehicle applications is described. The antenna used for the study is a variation on the ultra wideband monopole principle and covers all the frequency bands required for the Long-Term Evolution (LTE) standard. The design is intended for roof mount position on large vehicles for public transportation. Computational studies of the coupling between the two antennas at different locations on a metallic ground plane are included. Simulations were carried out using CST Microwave Studio. Initial measurements confirm the operation of the antenna.
