An environmentally compatible microstrip structure for electromagnetic signals in the microwave frequency range and higher. The microstrip structure according to the invention comprises at least two dielectric bodies made of an inorganic non-metallic material. Conductors of the microstrip structure are disposed on a first dielectric body. The ground plane of the microstrip structure is disposed on a second dielectric body. The dielectric bodies are so oriented that the second dielectric is between the at least one conductor and the ground plane while the first dielectric body is not. At least one cavitity is formed in the second dielectric body around at least one of the conductors to thereby create a composite dielectric comprising gas/air/vacuum of the cavity and the second dielectric body. The composite dielectric giving the microstrip structure adequate performance with dielectrically poor but environmentally compatible dielectric materials forming the dielectric bodies.

[ What is claimed is:] [1.] A microstrip structure for electromagnetic signals in the microwave frequency range and higher, which microstrip structure comprises a ground plane arranged at a predetermined distance from at least one conductor acting as a feeder having a first side towards the ground plane and a second side away from the ground plane, wherein the microstrip structure also comprises:a first dielectric body formed from an inorganic non-metallic material acting as a first carrier onto which first dielectric body the at least one conductor is disposed with the second side of the at least one conductor towards the first dielectric body,a second dielectric body formed from an inorganic non-metallic material acting as a second carrier onto which second dielectric body the ground plane is disposed,the second dielectric body being shaped and disposed inbetween the ground plane and the at least one conductor in such a way that at least one cavity is formed along the first side of at least one of the at least one conductor and between the first side of the at least one conductor and the second dielectric body to thereby form a composite dielectric with the second dielectric body, whereby a microstrip is formed which is disposable in an environmentally compatible way.
