Vertical antenna structure

Abstract

A vertical antenna structure is electrically fixed and connected to a main board of an electronic apparatus. The vertical antenna structure includes a circuit board, an electrode layer, and a semi-hole electrode layer. The circuit board is a square body with a front surface, a back surface, a top surface, a bottom surface and two side surfaces. The electrode layer is arranged on the front surface and the back surface of the circuit board. The semi-hole electrode layer is arranged on the bottom surface of the circuit board. The semi-hole electrode layer is electrically fixed and connected to the electrode layer. Moreover, the electrode layer and the semi-hole electrode layer are electrically fixed and connected to the main board.
