发明名称 ANTENNA SYSTEM
摘要 PROBLEM TO BE SOLVED: To provide a communication station which generates or receives an angular dispersion array of radiation beams. SOLUTION: An antenna system is equipped with an array of a plurality of radiation elements (100) which determine an array antenna (1) and abeam generator (120), which is equipped with a passive network including a 1st side (X) mounted with a plurality of beam ports for electric signals corresponding to the beams and a 2nd side (Y) mounted with a plurality of antenna ports corresponding to the radiation elements; and the respective beam ports are connected to a plurality of antenna ports through a network of a plurality of power distributor (52) components and a plurality of phase shifter (53) components; and the phase shifting of the phase shifters is an integral multiple of a specified constant. The array antenna (1) is a communication station which has triangular or hexagonal symmetry, and the array of beams is a communication system which has triangular symmetry or hexagonal symmetry and is not deformed substantially.
