A wideband automotive antenna for actual and future mobile communication 5G/LTE/WLAN with low profile

For integration into flat mounting volumes in cars a new wideband antenna is presented covering all frequency bands for cell phone LTE and 5G starting with the LTE low band at 698 MHz up to the WLAN frequency bands at 6 GHz. The performance of the antenna as a single part is shown by way of measurement and simulation and a pair of antennas is measured in a car on a turntable regarding its mutual coupling and influences of the mounting environment. It can be shown that for all the considered frequency bands the gain of the wideband antenna is deviating by only around 2.5 dB from the gain of a set of monopole antennas which are ideally matched for the different frequency bands.
