Abstract

PURPOSE:To make it possible to increase the gain of the circumference of a beam irradiation area when the titled antenna is used being mounted on an artificial satellite, by moving the primary radiators along center line away from a reflex mirror side or reflex mirror. CONSTITUTION:Radio waves from the primary radiators 3, 3', 3''... are reflected by reflex mirror 1 to radiate in different directions and those radiated beams are mixed into a composite beam. Then, the array surface of the primary radiators 3, 3', 3''... is shifted from vertical surface 5 that includes focus 2 and is at right angles to line 4 extending from focus 3 to the center of reflex mirror 1 to array surface 7 moved more than nearly at least one half as much as a wavelength toward the reflex mirror 1 side or away from reflex mirror 1.
