Abstract: The invention concerns an antenna arrangement (1) comprising: —a printed circuit board (2) having a metallised area (3) acting as a ground plane (3) in use, —a recess portion (4) in an edge portion of the ground plane (3), —a first electrically reactive network (9) bridging the recess portion (4)—a second electrically reactive network (16) bridging the recess portion (4), separately from the first electrically reactive network (9), wherein an electrical length of the recess portion (4) is 1/10th of a wavelength of the resonance frequency of the antenna arrangement (1) or less, and wherein a physical distance between the first (9) and second (16) electrically reactive networks (9, 16) is less than 1/12 of a wavelength of the resonance frequency of the antenna arrangement (1). The invention also concerns a device comprising an antenna arrangement (1).
Abstract: The present invention provides a solution to how an antenna of the Patch or PIFA type can be made from a sheet metal in order for thereafter to be mounted on a printed circuit board with particularly formed mounting areas in order to provide both an inexpensive but yet robust and efficient antenna solution.
