Abstract

A broadband antenna comprises a base plate, a radiator, a signal feed-in component and a ground component. The radiator comprises a first sub-radiator and a second sub-radiator. The first sub-radiator and the second sub-radiator respectively comprise a first end and a second end. The signal feed-in component is connected between the base plate and the first end of the first sub-radiator. The ground component is connected between the base plate and the first end of the second sub-radiator; wherein, the first sub-radiator and the second sub-radiator are arranged on the base plate with representing a shape of reversed V.

Description

technical field [0001] The invention relates to a three-dimensional broadband antenna and its related wireless communication device, in particular to a three-dimensional broadband antenna and its related wireless communication device with an inverted V-shaped metal sheet arranged on a substrate. Background technique [0002] With the vigorous development of wireless communication and the trend of miniaturization of mobile communication products, the layout position and space of the antenna are compressed, which relatively causes difficulties in design, and some embedded micro-antennas have been proposed. Generally speaking, the commonly used miniature antennas include chip antennas (Chip Antenna) and planar antennas (Planar Antenna), etc., and these types of antennas are characterized by small size. There are also many planar antenna designs, such as microstrip antenna (microstrip antenna), printed antenna (printed antenna) and planar inverted F antenna (Planar Inverted F An...
