| description | A high gain antenna equipment is provided by improving the gain with an optimal impedance matching with an antenna element (3) in a stored state as well as in an extended state. The antenna equipment is provided with a radio communication device (4) housed in a case (2), a pullout type antenna element (3), a coil (11) acting as a matching circuit element in an extended state of the antenna element (3) and as a helical antenna in a stored state, and a switch (12) connected to the coil (11) at one end which is brought into contact at the other end with a ground terminal when the antenna element (3) is in an extended state and which is brought into contact with an open terminal when the antenna element (3) is in a stored state. |
