Antenna module, preparation method thereof and terminal

Abstract

The invention discloses an antenna module, a preparation method thereof and a terminal. The antenna module comprises: a first substrate, wherein one side of the first substrate is provided with a grounding metal layer, a first signal pin and a second signal pin which are mutually insulated; a second substrate, wherein at least one first ultra-wideband radiation part and at least one first millimeter wave radiation part are arranged on the surface of the second substrate, and one side, far away from the first substrate, of the second substrate is provided with at least one millimeter wave decoupling part corresponding to the first millimeter wave radiation part; a third substrate, wherein one side of the third substrate is provided with at least one second ultra-wideband radiation part and at least one second millimeter wave radiation part; ultra-wide-band grounding via holes which are electrically connected with the corresponding first ultra-wide-band radiation part, the second ultra-wide-band radiation part and the grounding metal layer; ultra-wideband feed via holes which are connected with the corresponding second ultra-wideband radiation parts and the corresponding first signal pins; and millimeter wave feed via holes which are connected with the corresponding first millimeter wave radiation parts and the corresponding second signal pins. The millimeter wave antenna and the ultra-wideband antenna are integrated.

Description

technical field [0001] Embodiments of the present invention relate to antenna technology, and in particular to an antenna module, a manufacturing method thereof, and a terminal. Background technique [0002] With the rapid development of 5G technology, the application of antenna modules is becoming more and more extensive. [0003] Modern electronic devices usually need to integrate multiple antennas, such as integrated millimeter-wave antennas and ultra-wideband (UWB) antennas. However, UWB antennas and millimeter-wave antennas are usually designed as independent modules in communication products, giving the whole machine design space presents challenges and is costly to produce. Contents of the invention [0004] The present invention provides an antenna module and its preparation method and terminal, which organically integrates a millimeter-wave antenna and an ultra-wideband antenna on a module, which can meet the development needs of a smaller space for the whole mac...
