Abstract (en)

[origin: DE19707535A1] An antenna for receiving and transmitting electromagnetic microwaves having lambda wavelengths consists of a substrate layer (10) made of a low dielectric material which bears on one side a conductive ground plane (1) and whose opposite side is conductively structured as micro-strip circuits. The conductive structure (S) has an elongate conductor section (3, 3a, 3b, R, Ra, Rb) which acts as a resonator and whose length (LR) is shorter than lambda epsilon /4. One end of said conductor section is conductively connected to the ground plane (8, 1) and its other end is conductively connected to at least another conductor section (2, 2a, 2b, 4, 42a, 42b, 46a, 46b, K) used as an end capacitor to adjust resonance conditions. The conductor section (3, 3a, 3b, R, Ra, Rb) which acts as a resonator is connected to the inner conductor of a coaxial optical fibre and the outer conductor of the coaxial optical fibre is connected to the ground plane (1).
