A planar antenna device comprises a ground plane, a planar antenna element having a principal plane mounted above the ground plane, and a cavity, having an opening partially exposing the antenna element, placed on the ground plane in order to cover the entire antenna element contactlessly.

Planar antenna device

A planar array antenna includes a ground plate formed of metallic material, a plurality of patch antenna elements supported on the ground plate by insulation spacers, respectively, and arrayed at a predetermined pitch, and a feed line for coupling adjacent antenna elements of the plurality of patch antenna elements.

An illuminant-mounted antenna includes a rod-shaped antenna element, an illuminant mounted on top of the rod-shaped antenna element, and lighting means for lighting the illuminant by high frequency energy generated on the rod-shaped antenna element when a portable transceiver is operated. The lighting means includes a high frequency detecting diode and an inductive element. One end of the high frequency detecting diode and one end of the inductive element are connected in common to the top of the rod-shaped antenna element, and the other end of the high frequency detecting diode and the other end of the inductive element are connected to both ends of the illuminant. It is preferable that the rod-shaped antenna element be a whip antenna element capable of transmitting/receiving a very-high-frequency radio wave and an ultra-high-frequency radio wave, and an antenna element mounted on the portable transceiver, the illuminant be a light-emitting diode whose current ranges from 10 mA to 20 mA, and the inductive element be a coil whose inductance ranges from 13 nH to 40 nH.

In a window of an office of a banking facility, there is disposed a composite apparatus in which a window machine facing the teller is united with an automatic cash handling machine facing the lobby and which is integrally configured in a window counter. During the office hours of the window, the window machine of the composite apparatus is employed by the teller for banking services. In a period of time beyond the office hours, a shutter for prevention of crimes is moved downward onto the window counter, which enables the users to externally access the automatic cash handling machine.
