Abstract
An antenna device includes an array antenna formed of five radiating elements arrayed on a dielectric substrate, and a feeder circuit that feeds a high frequency signal to the radiating elements making up the array antenna. The five radiating elements are arrayed on a first straight line drawn in a direction horizontal to the ground, and an excitation voltage of the radiating element positioned at the center of the array is set to be 2.2 times or more an average value of excitation voltages of the other radiating elements.
