PROBLEM TO BE SOLVED: To provide an antenna system which can control directivities of a plurality of radiation elements by using one parasitic element. SOLUTION: The antenna system 100 includes two radiation elements 194 arranged on a base 102 parallel to each other, and a parasitic element 114 disposed between the two radiation elements 104, and radiation directivity is controlled according to the length of the parasitic element 114. This configuration provides a compact antenna system including a plurality of radiators with desired directivity. COPYRIGHT: (C)2009,JPO&INPIT
