Abstract

Provided is an antenna-integrated module that is easy to realize miniaturization, can easily prevent unauthorized modification of circuits, and can efficiently perform a reflow process for low-cost manufacturing. The component group (3) is mounted on the circuit board (1) provided with the wiring pattern and the ground conductor layer (2), and the sheet metal case and antenna element (4) mounted on the circuit board (1) covers the circuit components group (3). The antenna element (4) is provided with: a rectangular top plate (5) with an opening (5a), a power supply pin (6) connected to the power supply line of the wiring pattern, and a short circuit connected to the ground conductor layer (2). Legs (7) and (8), electrically open fixed legs (9-11) and side plates (12-15) with openings (12a-15a), and each leg (6-11) is welded on the circuit board (1).

Description

technical field [0001] The present invention relates to an antenna-integrated module suitable for use as a small receiving and sending unit for communication or broadcasting. Background technique [0002] In recent years, along with the development of wireless communication technology, various electronic devices or wireless cards incorporating small receiving and transmitting units have been proposed. This type of receiving and transmitting unit is an antenna-integrated high-frequency module equipped with an antenna element on a circuit board provided with a high-frequency circuit. There is a predetermined area on the circuit board of the main part of the high-frequency circuit, and an antenna element such as a chip antenna or a pattern antenna is provided on the other area of ​​the circuit board (for example, refer to Patent Document 1). [0003] However, in the structure in which the antenna element and the shield are juxtaposed in different regions on the circuit board a...
