PROBLEM TO BE SOLVED: To provide a directional antenna which is made small and freely selects a direction. SOLUTION: In the directional antenna for controlling directivity by short-circuiting a parasitic patch 3 to ground, resistors 12a, 12b and 12c are provided at positions short-circuited to the ground, and the directional antenna is short-circuited to the ground through the resistors 12a, 12b and 12c.
