Embodiment Construction

[0040] figure 1 is a perspective view of a circuit board assembly of a wireless electronic device according to a first embodiment of the present invention. The assembly of the circuit board 10 includes a main printed circuit board (PCB 100 ) (commonly referred to as a motherboard), an additional printed circuit board 200 (separate from the main PCB 100 ), and an antenna element 300 . The antenna element 300 is located at the edge of the main PCB for optimal radiation behavior.

[0041] The main PCB 100 is equipped with a ground layer 120 and electronic components (not shown) for functional operations of the electronic device. The additional PCB 200 is equipped with a wireless module (not shown) including one or more electronic components for wireless operation of the electronic device, and a feeder 220 connected to the wireless module. These electronic components for wireless operation of the electronic device include transceiver circuitry for processing RF signals transmitt...

Abstract

A circuit board assembly for an electronic device, comprising: a main circuit board provided with a ground plane and at least one electronic component for performing one or more functions of the electronic device; a wireless module board spaced apart from and over the main circuit board, the wireless module board being provided with a feed line and at least one wireless module for performing wireless operations; and an antenna element for wireless communication, the antenna element comprising a resonating element, a first connection element connected to the feed line of the wireless module board and a second connection element connected to the main circuit board.

Description

technical field [0001] The invention relates to a circuit board assembly and a wireless electronic device comprising the circuit board assembly. Background technique [0002] Electronic wireless devices such as mobile phones, tablets, set-top boxes and gateway devices are equipped with at least one antenna and corresponding wireless functional components for analyzing received signals from the antenna and / or via The signal sent by the antenna is processed. [0003] A wireless module including wireless functional components for wireless applications can be integrated in an electronic device in several ways. In some cases, the wireless functional components are provided directly on the main circuit board, while in other cases, the wireless functional components are provided on a separate circuit board. Interconnection elements are provided to carry radio frequency signals between the two circuit boards. Providing the wireless functional components on a separate board has th...
