Abstract: Disclosed is a high frequency tuner module, including: a circuit component; signal lines; a GND line; and a multilayer board formed by laminating a plurality of layers, wherein the circuit component is placed on a top layer surface of the multilayer board; the signal lines and the GND line are formed inside the multilayer board; and among the signal lines, high frequency signal transmitting signal lines to transmit a high frequency signal are formed on a single layer inside the multilayer board.

Abstract: An RF input portion is formed on a printed circuit board and is operable to input a high-frequency signal received by an antenna device. An electronic component is mounted on the printed circuit and is operable to process the input high-frequency signal. The RF input portion has a specific pattern adapted to be electrically interchangeably connectable with a plurality of types of connections.

Abstract: Disclosed is a high frequency wave tuner module including a circuit board having an approximately rectangular shape, which is made of ceramic material and a shield cover to shield an interfering wave by covering a circuit part mounted on a board surface of the circuit board, and a position of the shield cover in a height direction with respect to the board surface is determined by fixing the shield cover to the board surface at four corner positions of the circuit board, and a position of the shield cover in a board surface direction with respect to the circuit board is determined by engaging at least two side walls of the shield cover which extend in a thickness direction of the circuit board, with end surfaces of the circuit board, which correspond to the two side walls.

Abstract: A circuit board has a first face and a second face opposite to the first face. An electronic component is mounted on the second face. An insulative sheet is disposed between the first face of the circuit board and an antenna and having an electromagnetic shielding property.

Abstract: An antenna unit includes a feeding component 40 and a metal plate 50 on which the feeding component 40 is mounted. The feeding component 40 has an attaching member 43 made of resin to support a feeding line against the metal plate. The metal plate 50 has a pair of cut and raised parts 51 at both ends thereof while the attaching member 43 has a pair of locking hooks 432 at both ends thereof. The locking hooks are partly inserted into the cut and raised parts and thereby the feeding component is attached to the metal plate without projecting any parts of the attaching member from a rear surface of the metal plate.

Abstract: A feeding component 40 has a wire (or a feeding line) 42 and an attaching member 43 made of resin. The attaching member 43 provides wire receiving grooves 43a and 43b to receive and support the wire 42. At least one pair of wire holding parts 43d are formed on inner wall defining the wire receiving grooves 43a and 43b. The wire holding parts 43d of each pair are opposite to each other and inclined to narrow a width of the wire receiving groove 43a or 43b with increasing proximity to an upper side of the wire receiving groove 43a or 43b. The wire holding parts 43d hold the wire 42 put into the wire receiving grooves 43a and 43b.
