Abstract: An antenna unit for receiving and/or emitting electromagnetic waves having a certain wavelength is described. Said antenna unit is a slotline antenna unit having a slot region. Said antenna unit comprises at least one antenna element and a first carrier. Said first carrier is made by a dielectric material wherein said first carrier has at least one cutout in said slot region. Said antenna element is made by a printed circuit board. Said antenna element and said first carrier are attached to each other wherein said first carrier has a thickness being less than one fifth of said wavelength. Further, a radio frequency circuit and a method for manufacturing an antenna unit are described.

Abstract: An antenna element for receiving and/or emitting electromagnetic waves is described. Said antenna element comprises a conductive portion made of a conductive material and a resistive portion made of a resistive material. Said conductive and resistive portions are directly adjacent to each other along at least 50% of at least one outer edge of the conductive portion wherein said antenna element is a tapered slotline antenna element. Further, an antenna system is described.
