Claims

[Scope of utility model registration request]

(1) A casing made of a metal body, a plate-shaped radiating conductor that is in contact with one surface of the casing and whose facing surface has the same shape as a part of the one surface of the casing, and this radiating conductor. An antenna comprising: a holder attached to one surface of the casing so as to be openable and closable; and a dielectric plate provided at a predetermined position on one surface of the casing to insulate the radiation conductor from the holder.

(2) The antenna according to claim (1) of the utility model registration, characterized in that an impedance matching circuit connected to a plate-shaped radiation conductor is formed on a dielectric plate.
