Definitions
- the field of the invention is that of wide bandwidth antennas with a hemispherical or quasi-hemispherical radiation pattern. More specifically, the invention relates to resonant helical antennas operating in two neighboring frequency bands corresponding to transmission and reception, and in particular the decoupling of these two channels, and therefore the duplexer function.
- duplexer This is the role of the duplexer, generally placed at the antenna feed point.
- duplexers Several types are known. The document "RF filters and
- Figures 1 and 3 show a sectional view of the mounted antenna, comprising the propellers of Figures 2 and 4, mounted offset;
- Figure 6 shows in more detail the supply structure of Figures 1 and 3;
- Figures 7 A to 7C illustrate the design of a -3 dB 90 ° coupler according to the invention: - Figure 7A: conventional coupler in distributed elements;
- FIG. 7B corresponding representation using cells in ⁇ ;
- FIG. 7C corresponding microstrip line coupler;
- Figures 8A and 8B illustrate the design of a -3 dB coupler
- the invention can be applied to any type of helical antenna.
- the preferred embodiment described above relates to an antenna with quadrifilar propellers.
- the assembly is then wound inwards (arrow 52) on a support which is transparent from the radioelectric point of view, in order to provide the internal propeller of FIG. 4.
- Figures 10 and 11 relate to the radiation patterns measured in right circular polarization (a) and in left circular polarization (6), with a dipole rotating respectively at frequencies 1.98 GHz ( Figure 10) and 2.2 GHz ( Figure 11).
