A first radiating element is formed from the feed end-first connection pin 211-first radiating portion 212, and the antenna length of the first radiating element is the shortest, and the corresponding frequency is the highest, which is the high-frequency radiating element in the present embodiment; the second radiating element is formed from the feeding end, the first connecting pin 211 and the second radiating portion 213, and is an intermediate frequency radiating element in this embodiment, and the total lengths of the antennas of the first radiating element and the second radiating element are different, so that the working frequencies of the two radiating elements are also different, thereby achieving the effect of expanding the bandwidth of the antenna.
Further, in order to achieve the coupling connection between the second radiator 22 and the base coupler 1 and further expand the bandwidth of the wideband separation antenna 1000, the second radiator 22 includes a third radiator 222, a fourth radiator 223, and a second connection pin 221, where the third radiator 222 and the fourth radiator 223 are respectively disposed at two ends of the second radiator 22 opposite to the base coupler 1, the second connection part on the second radiator 22 is bent toward a side close to the base coupler 1 to form the second connection pin 221, and the third radiator 222 is disposed at a side close to the first radiator 21, and the second connection pin 221 is electrically connected to the base coupler 1.
