A Wideband Low-Profile Antenna for LTE/5G

A wideband low-profile antenna for Long Term Evolution (LTE) and 5G technology is presented in this paper. It is designed to be mounted on a car roof underneath the shark-fin cover. Proposed antenna operates at a wide frequency range from 617 MHz to 5.5 GHz. Wide frequency band is obtained without using any matching network in the design. Antenna has an omnidirectional radiation pattern throughout the band. Antenna prototype is fabricated and preliminary measured results in terms of input impedance matching are shown.
