Abstract

PURPOSE:To miniaturize an antenna and to mount the antenna on a restricted space by controlling ON/OFF of two switches, shorting any one of two adjacent sides of a square radiation conductor plate and switching polarized waves. CONSTITUTION:The switches 4, 5 are arranged on positions separated from a short conductor 3 by a fixed distance respectively along two sides of the radiation conductor plate 2 which are close to the conductor 3 and a ground conductor plate 1 and a radiation conductor plate 2 are connected to both the ends of respective switches 4, 5. When the switch 4 is turned on and the switch 5 is turned off, a short conductor 3 of the plate 2 and the side close to the switch go to almost a short state and the other three sides go to an opened state, so that a main polarizing face goes to parallel with the YZ face. When the switch 4 is turned off and the switch 5 is turned on, the main polarizing face goes to parallel with the XZ face, i.e. vertical to the YZ face. Thus, polarizing face can be switched by turning on and off the switches 4, 5.
