Abstract

A helix antenna especially aimed for the satellite connections of mobile devices. The antenna (300) is to be fed from above, and all its radiators are side by side on a same geometric cylindrical surface. The antenna has at least two resonances. In the case of two-resonance every second radiator (321, 323, 325, 327) resonates at a lower frequency and the rest of the radiators (322, 324, 326, 328) at another, higher frequency, the frequency difference being based on the difference in the physical length of the radiators. One conductor of the feed line of the antenna is connected directly to a half of the radiators and the other conductor to the second half of the radiators. No separate feed circuit for the phase shifts is required in an antenna with plurality of helix radiators,because the phasing can be implemented by the positioning of the radiators and the fine tuning of their length. The antenna structure is simple, in which case its production costs are relatively low.
