Abstract: A self-grounded bowtie antenna arrangement including an antenna structure including a number of antenna petals including arm sections tapering towards a respective end tip portion and being made of an electrically, conducting material, the end tip portions being arranged to approach a base portion on a first side thereof and to be connected to feeding ports, a specific port being provided for each antenna petal. The base portion includes a conducting ground plane or a Printed Circuit Board, and each antenna petal is made in one piece from a metal sheet or similar, and it is adapted to be fabricated as separate units, and to be mountable onto a front or back side of the base portion or ground plane by means of surface mounting. The ground plane may be a Printed Circuit Board, meaning that the bowties can be mounted by automatic placement and soldering machines.
