Abstract
A radiation antenna for wireless communication provides an advantage of being able to enhance gain and control directionality, while suppressing the height. The radiation antenna for wireless communication includes a line antenna element 10 and arm elements 20. The line antenna element 10 extends from a power feed section 15. The arm elements 20 are connected to a tip portion of the far side from the power feed section 15 to enhance the gain of the line antenna element 10 and control the directionality thereof. The electrical length from the power feed section 15 to the open end of the arm elements 20 by way of the line antenna element 10 is designed to resonate at a higher order mode of a target frequency.
