PROBLEM TO BE SOLVED: To provide a miniaturized, lightweighted and high-productivity antenna having a dielectric board by forming a ground conductor on one planar surface of dielectric and the side surface of prescribed width continuous to the planar surface. SOLUTION: A patch 1 is a radiating conductor composed of metallic foil such as copper having a rectangular dimension of 27.9mm×26.9mm. A dielectric board 2 is composed of the flat plate having a rectangular dimension of 30mm×30mm and the thickness of 4mm with PPS as a base. The patch 1 is adhered on one surface of board 2, and a ground 3 composed of metal foil such as copper is adhered on the other surface. Its peripheral edge is adhered over all the periphery of side surface of board 2 with prescribed width H along the side surface of board 2. Besides, a coaxial probe 105 is provided on the side of ground 3, and the probe 105a is electrically connected through the board 2 and the ground 3 to a power feeding point 106 on the patch 1 while being electrically disconnected from the ground 3. Besides, a line 105b to be covered is connected to the ground 3 and grounded to a ground 104.
