Patent ID: 6947011

Claim:
A connector unit for a high frequency radio apparatus having a housing, a first internal antenna provided inside the housing, a radio unit provided inside the housing for processing a radio signal, and an external antenna capable of being inserted and drawn from outside the housing, comprising: a printed board including a first microstrip line connected to said radio unit and a second microstrip line connected to said first internal antenna; a fixed contact provided on said printed board and connected to said second microstrip line; an elastically-deformable, movable contact provided on said printed board and connected to said first microstrip line, and urged toward said fixed contact; and a socket for covering said movable contact and said fixed contact, wherein a distal end of said external antenna enters between said movable contact and fixed contact when said external antenna is inserted into said socket, the distal end of said external antenna abuts on said movable contact and presses said movable contact to separate the movable contact from said fixed contact, and said external antenna is matched in impedance and connected to said radio unit, and wherein said movable contact abuts on said fixed contact when said external antenna is drawn from said socket, and said first internal antenna is matched in impedance and connected to said radio unit.
