Abstract

PURPOSE: To prevent the reduction in gain and to suppress thermal noise generated in the inside of an antenna lower by arranging a horn antenna in an array, connecting a waveguide to the connection of horn antennas so as to combine power through the waveguide.
CONSTITUTION: Horn antennas 1 are arranged as an array, waveguides 2, 3 are connected to the connection of each horn antenna 1 to combine the power with the waveguide. For example, 16 horn antennas 1 are arranged in an array of 4×4 to constitute the horn array antenna. The radiation efficiency of the horn antenna 1 is ≥80% being close to 90% and the waveguide 2 is directly connected to the horn 1 integrally to reduce the connection loss. Thus, the decrease in the gain is prevented and the thermal noise caused in the inside of the antenna is suppressed lower.
