摘要：
An antenna device includes an array antenna 2 formed of five radiating elements 21 to 25 arrayed on a dielectric substrate 1, and a feeder circuit 3 that feeds a high frequency signal to the radiating elements 21 to 25 making up the array antenna 2. The five radiating elements 21 to 25 are arrayed on a first straight line L1 drawn in a direction horizontal to the ground, and an excitation voltage of the radiating element 23 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 21, 22, 24, and 25.
