This application relates to the field of communication equipment technology, and in particular to a portable ultra-wideband antenna device for a four-in-one 5G backpack. It includes an antenna housing and a multi-in-one connector disposed within the antenna housing. The multi-in-one connector also electrically connects to a radio frequency (RF) connector. An antenna radiating element group is located inside the antenna housing and electrically connected to the RF connector. The antenna radiating element group includes a first antenna, a second antenna, a third antenna, and a fourth antenna arranged sequentially at intervals along the vertical direction of the antenna housing. In this application, the multi-in-one connector integrates the feed lines of the four antenna elements onto a single interface, simplifying the connection to the RF connector and achieving a compact structure. It integrates four independent antenna systems into a lightweight fiberglass rod, avoiding the cumbersome and bulky nature of externally mounted multiple antennas, perfectly meeting the operational or emergency needs of individual soldiers carrying and moving quickly.
