Abstract: The invention relates to a microstrip arrangement comprising a first and a second microstrip conductor. The two microstrip conductors have essentially the same dimensions in their longitudinal direction and transverse direction, and are galvanically interconnected by means of at least one connection. The two microstrip conductors also extend essentially parallel to one another on either side of a dielectric material. As a result of this design of the microstrip arrangement, the field losses and also other influences caused by the dielectric material will be very considerably reduced, and in practice a resultant microstrip arrangement is obtained, which, with regard to its electrical performance, appears to be suspended in the air. Preferred embodiments comprise a microstrip antenna, a circuit board and a conductor application.

Abstract: A single-frequency antenna arrangement includes a ground plane, a dielectric substrate, a first antenna contour located on a first side of the dielectric substrate and a second antenna contour located on second side of the dielectric substrate. The first antenna contour and the second antenna contour have substantially the same dimensions in their longitudinal directions and transverse directions. The first antenna contour and the second antenna contour are galvanically interconnected by at least one connection.
