<P>PROBLEM TO BE SOLVED: To provide a microstrip array antenna less susceptible to loss of an electrical connection between radiation antenna elements and a feeding strip line even by vibration of a substrate. <P>SOLUTION: A microstrip array antenna 60 is formed on a front side surface of a dielectric substrate having a conductor ground layer on a rear surface thereof. The microstrip array antenna 60 includes: a linear feeding strip line 63 having an input terminal 65 and an output terminal 66; and rectangular radiation antenna elements 44a, 44b, 44d and 44e each having an axis in a direction inclined at an angle of 45 degrees from a direction of the output terminal with respect to an axis X of the feeding strip line 63. The radiation antenna elements 44a, 44b, 44d and 44e are overlapped with and connected to the feeding strip line 63 so that opposing two peaks Q and S of four peaks P, Q, R and S of these radiation antenna elements are located on both sides of the feeding strip line 63. <P>COPYRIGHT: (C)2013,JPO&INPIT |
