Abstract This study offers a compact three-dimensional antenna solution for the automotive sector. To fit in a shark-fin enclosure, a printed circuit board and metal sheet can be used to make the antenna. The antenna system covers LTE, GPS, WLAN, and WAVE bands (850 MHz, 1575 MHz, 2.4 GHz, and 5.9 GHz, respectively). Because of their low-profile design, planar inverted-F antennas (PIFAs) are commonly used as MIMO antennas in the LTE spectrum. Modified planar monopoles are used to produce omni-directional radiation patterns in the WLAN and WAVE bands. Antenna qualities that can be employed in automobiles have been modelled and tested. Using a shark-fin antenna, a novel vehicle-ready MIMO-LTE, GPS, WLAN and WAVE (850/1575 MHz, 2.4 and 5.9 GHz) solution has been shown. It is completely integrated. In addition to the two PIFAs and two modified monopoles, the solution includes a simple and low-cost manufacture method for a separate patch. It is designed to fit in a shark fin case when fitted on a level surface. Despite the lack of matching or decoupling networks, measurements and modeling reveal that this antenna system performs well in terms of return loss, radiation pattern, and isolation.
