Abstract
A built-in straight mobile antenna type dual band antenna assembly includes a circuit board, a first radiator transversely arranged on one end of the circuit board and having a first resonance frequency, and a second radiator longitudinally arranged on one lateral side of the circuit board. The first radiator and the second radiator constitute an L-shaped structure for signal input through a feed end, and are connected to a ground plane on the circuit board through a common grounding lug.
