titleOfInvention | Arrangement for decoupling two low-directional aerials |
abstract | The invention relates to antenna technology. The purpose of the invention is to reduce the transverse dimensions and provide simultaneous separation in two wavelengths. The initiating structure 1 is designed as a package of segments 5 of the first rectangular waveguides (PV) in contact with wide walls 6, which are symmetrically located with respect to the plane passing through the centers of the apertures of two antennas 2 and 3 perpendicular to the plane of the common shield 4. The open ends of the segments of the first The PVs lie in the plane of the screen 4, and their second ends are docked with the open ends of the short-circuited segments of the second PV with the smaller size of the wide wall. The dimensions of segments of the first and second ratios are selected from MF λ 1 ≥A 1 * 98l 1/2, λ 1 / 2≥A 98l 2 * 2/2, L = 3λ 1 / 16√1- (λ 1 / 2A 1) 2 , L = 10λ 2 / 16√1- (λ 2 / 2A 2) 2, B≤λ 1/3, where λ 1, λ 2 - maximum wavelength LF and HF wavebandsn n n a 1 and 2 - the size of the wide wall of the 1st and 2nd PVn n n L 1 - the length of the segment 1 PVn n n L - total length of segments of the 1st and 2nd PVn n n B - the size of the narrow wall of the 1st and 2nd PV. Wo can operate in two wavelengths that differ by half, and its transverse size is at least two times smaller. 2 Il. |
