PROBLEM TO BE SOLVED: To stably match impedance even if the interval of antenna elements is made narrow. SOLUTION: An array antenna shown in Fig1 includes a linear first array element 11, second array element 12, first conductor 21, second conductor 22, third conductor 23, and fourth conductor 24. Furthermore, it is illustrated that the conductors are disposed around each of the array elements while spaced away by a predetermined interval. In such a case, an RF signal from a transmitter that is not shown is applied to an array element, thereby also calling it power feeding element. An RF signal is not applied to a conductor, on the other hand, thereby also calling it parasitic element. COPYRIGHT: (C)2007,JPO&INPIT
