Abstract:
An antenna for receiving and transmitting of electromagnetic microwaves of wavelength .lambda., consisting of a substrate layer (10) made of low-dielectric material, which on one side is provided with conductive ground plane (1) and whose opposite side is a conductive structure in the form of micro-strip circuits, and charaterized by the face that the conductive structure (S) has a longitudinal conductor section (3, 3a, 3b, R, Ra,Rb) as resonator, whose length (L.sub.R) is shorter than .lambda..sub.g /4, and which is conductively connected with the ground plane (B, 1) at its end, and whose other end is conductively connected with at least one other conductor section (2, 2a, 2b, 4, 42a, 42b, 46a, 46b,K), which serves as end capacitance for the purpose of adjusting the resonance condition, whereby the resonator conductor section (3, 3a, 3b, R, Ra, Rb) is in connection with the ground plane (1) using an internal conductor of a coaxial wave guide and the external conductor of the coaxial wave guide.
