SOLUTION: A start point is a transmission point or a previous reflection point. The magnitude of elevation angle components and azimuthal angle components are compared in polar coordinate components (1, θ, ϕ) of a propagation-directional unit vector from the start point to an end point as a coordinate point in the radio wave radiation direction and polar coordinate components (1, θi, ϕi) of n peak-directional unit vectors from the start point to end points as peaks on walls of a n-polygonal shape. θmin≤θ≤θmax (θmin is the minimum of the elevation angle component of θi. θmax is the maximum of the elevation angle component of θi.), ϕmin≤ϕ≤ϕmax (ϕmin is the minimum of the azimuthal angle component of ϕi. ϕmax is the maximum of the azimuthal angle component of ϕi.). If θmin≤θ≤θmax or ϕmin≤ϕ≤ϕmax is not satisfied, the walls of the n-polygonal shape are excluded from the reflection wall face, and the propagation route is searched.

SOLUTION: Length that is nearly half wavelength out of an antenna element formed by a conductive board is arranged along the inside of the enclosure of the upper end of the portable radio unit 6 as a monopole section 1. Length that is nearly the quarter wavelength in the antenna element is arranged in parallel with the surface of a base plate 5 of the portable radio 6 as an inverse F antenna section 2. The direction where the inverse F antenna section 2 is arranged is set in parallel with (Y-axis direction) the upper end of the portable radio unit 6. The inverse antenna section 2 is grounded to the base plate 5 via a ground point 3 that is provided at one end. A power feed point 4 is provided away from the ground point by a specific distance. The configuration eliminates the need for a matching circuit, simplifies the configuration of the portable radio, and allows a high antenna gain to be obtained in various usage states.
