Abstract

PURPOSE:To achieve wide band and to enahble to switch the directivity easily, by providing a feeding point to a conductor corresponding to each ridge constituting one surface of a rectangular parallelepiped and loading a resistor to a conductor corresponding to each ridge constituting other surfaces. CONSTITUTION:An antena conductor AL consists of conductors A1-D1, E-H and A2- D2 corresponding to 12 ridges of a rectangular parallelepiped, power feeding points a,a';b,b';c,c';d,d' are provided at the middle of the conductors A1-D1 constituting one surface of the rectantuglar parallelepiped, a main antenna conductor M of loop shape consists of the conductors A1-D1, resistors Ra-Rd are loaded at the middle of conductos A2-D2, and the conductors A2-D2 form a subantenna- conductor S. A switch is selected and connection is made to an output terminal via one feeding point out of the points of a,a'-d,d' of the antenna conductor AL through changeover, the remaining feeding points are terminated by a terminating impedance element and a pair of opposing feeding points are in cross connection.
