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.
