Title:
HIGH FREQUENCY ELECTRONIC COMPONENT, COMMUNICATION DEVICE AND METHOD OF MANUFACTURING COMMUNICATION DEVICE
Document Type and Number:
Japanese Patent JP2015220536
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To facilitate adjustment of the high frequency output characteristics.SOLUTION: An antenna 300 of a high frequency demultiplexer includes a bottomed cylindrical antenna body 320 having one open end in the axial direction, and a spring 340 housed in the antenna body 320, and having a protrusion 342 protruding outward from a slit 324 formed in the peripheral surface of the antenna body 320. When fitting a tool 500 in the opening of the antenna body 320, the spring 340 flexes and the protrusion 342 is drawn into the antenna body 320. Since the protrusion 342 of the spring 340 is energized by the mounting hole of the high frequency demultiplexer, when the tool 500 is not fitted in the opening of the antenna body 320, its position can be held without loosening or tightening a fixing nut, every time when adjusting the protrusion of the antenna 300.
