This linear antenna 14 is covered with an insulating tube 16 made of resin or the like on the outer periphery. A second antenna 18 such as a coil antenna is provided at the tip of the linear antenna 14, and a cap 20 made of resin or the like is put on the second antenna 18. Further, a first large-diameter portion 22 made of a conductive material to which the proximal end of the second antenna 18 is electrically connected is provided at the distal end of the linear antenna 14. The first large-diameter portion 22 may or may not be electrically connected to the tip of the linear antenna 14.

When the antenna is pulled out, the power supply fitting 1
The antenna impedance at 2 is that if the linear antenna 14 and the second antenna 18 are not electrically connected,
This is the impedance of the linear antenna 14, and if electrically connected, the second antenna 18
Is the impedance of the added antenna. In any case, it is difficult to make the antenna impedance the same between the housed state and the pulled-out state of the antenna. However, matching with the coaxial cable 32 is performed by one matching circuit 30, and proper matching is not necessarily achieved in both the drawer and storage states. Therefore, the antenna performance cannot be fully utilized, and sufficient gain has not been achieved.

A linear antenna that can be pulled out of and housed in a housing and a second antenna that is provided at an end of the linear antenna and that is located outside the housing when the linear antenna is housed. A first antenna having a first large-diameter portion electrically connected to a base end of the second antenna at a distal end of the linear antenna; and a linear large-diameter portion provided at a base end of the linear antenna. A second large-diameter portion electrically connected to a base end of the antenna is provided, and the first large-diameter portion is provided in the housing so that the linear antenna penetrates movably in the axial direction and is stored in the antenna. A first power supply fitting to be fitted and electrically connected is fixed, and the linear antenna penetrates the first power supply fitting through an insulating cylinder so as to be coaxially insulated and movably in the axial direction. The second large-diameter portion is fitted and electrically connected when the antenna is pulled out. A second power supply fitting, and the first and second power supply fittings are respectively connected via different first and second matching circuits, or one is provided with a matching circuit and the other is provided with a matching circuit. An antenna for a communication device characterized by being directly connected to a coaxial cable without being connected.

A first large-diameter portion is provided, and a first power supply fitting is fixed to the housing, and a base end of the second antenna is fixed to the first power supply fitting and electrically connected thereto.
The linear antenna is pulled out and housed in an insulated state coaxially with the power supply fitting and the second antenna, and the linear antenna is coaxially formed in an insulated state with the first power supply fitting via an insulating cylinder. A second power supply fitting is provided that penetrates freely in the axial direction and that the large-diameter portion fits and is electrically connected in an antenna pulled-out state, and the first and second power supply fittings are respectively provided with different first power supply fittings. And a second matching circuit, or one connected directly to a coaxial cable via the matching circuit and the other directly without a matching circuit.
