PURPOSE:To distribute and collect radio signals efficiently between one master station with higher than the microwave band and plural slave stations, by connecting a main antenna device to respective subantenna devices through a feeding system including a reflector. CONSTITUTION:A radio wave from the master station antenna device 1 passes through a radio wave propagation path 4, and is reflected by the main reflector 6 of the device, received by the primary radiator 7 of the device 1, and then guided to a subantenna device 8 by a power distributor 10 through a feeding waveguide 9 to be radiated in respective main beam directions. Electric power is collected in respective directions to the device 1 reversely and transmission and reception are carried out simultaneously. |
