PROBLEM TO BE SOLVED: To provide a planar antenna device where phases of respective antenna elements become the same phases while suppressing grating lobes, in a micro strip array antenna. SOLUTION: Large power is supplied to each of the antenna elements 101 at the center of the planar antenna device 100 by forming a micro strip line (a stub line 106) at the center of the planar antenna device 100. Consequently, the planar antenna device is obtained capable of suppressing the grating lobes without using asymmetric T shape branch as power feeding wiring 102. COPYRIGHT: (C)2008,JPO&INPIT
