PURPOSE:To attain inexpensive constitution and to reduce weight and size by using a non-polarization wave switching bit phase shifter in common with respect to two elements antennas in pairs. CONSTITUTION:An input from a point P is divided into four by a 4-distributor 4 and inputted to digital phase shifters 5a-5d. The digital phase shifters 5a-5d consists of the non-polarized wave switching phase shifters 51, 52 of 22.5 deg. or 45 deg. bit used in common for two element antennas used as a pair, a 2-distributor 57, and polarized wave switching 90 deg. and 180 deg. bit phase shifters 53, 54, 55, 56 provided with each element antenna. The digital phase shifters 5a-5d are subjected to phase shift to direct a beam in a desired direction in response to the bit set thereto and subjected to phase shift to synthesize a desired polarized wave and the radiation in conducted from element antennas 11a-14b. |
