Terminal antenna used in wireless local area network

Abstract

The invention discloses a terminal antenna used in a wireless local area network. The terminal antenna comprises a radio frequency connector, a feeding cable, a suction cup base, a 2.4G band antenna,a 5G band antenna and a combiner. The left side of the suction cup base is provided with a mounting screw and is fixedly installed with the 2.4G band antenna, the right side of the suction cup base isprovided with a mounting screw and is fixedly installed with the 5G band antenna, the top portion of the suction cup base is provided with a mounting screw and is fixedly installed with the combiner,the combiner is internally provided with a frequency division unit circuit board, the frequency division unit circuit board is provided with a 2.4G band feed connection, a 2.4G band grounding connection, a 5G band feed connection and a 5G band grounding connection, and the 2.4G band antenna and the 5G band antenna are welded and fixed with the output end of the frequency division unit circuit board through respective connection cables. The volume is small, the weight is light, the anti-interference ability is strong, the frequency band is wide, the gain is high, and the radiation performanceindex is good.
