Circularly polarized patch antenna for use in body sheet of motor car, has supply structure comprising phase shifter-arrangement that is connected with emitter surface at two connection points under effect of phase shift

摘要

The antenna (1) has a dielectric substrate (3) comprising an upper side (3a), a lower side and side walls (3c) running between the upper and lower sides. An electrically-conducting emitter surface (11) is arranged on the upper side or lower side. The emitter surface is moved on the walls, and a side surface-emitter structure (18) is galvanically connected with the emitter surface. The structure has side emitter surface-sections (19), and a supply structure (15) has a phase shifter-arrangement that is connected with the emitter surface at two connection points under the effect of phase shift.
