Abstract: 1446999 Aerials SIEMENS AG 2 Oct 1974 [31 Oct 1973] 42686/74 Heading H4A In a dual-band omni-directional aerial system a double coaxial line is provided having inner, intermediate, and outer conductors 9, 5, 6, Fig. 1. When in a vertical position there is formed for the lower frequency band an outer coaxial line section 13 terminating in a lower radiating element and constituted by the intermediate and outer conductors 5, 6. There is also formed for the higher frequency band an inner coaxial line section 10 terminating in an upper radiating element and constituted by the inner and intermediate conductors 9, 5. Each radiating element is of one of two types, and the two radiating elements may be of the same or different types. In the embodiment shown in Fig. 1 the lower frequency element is of a first type, in which the outer conductor 6 of the coaxial line section 13 is extended to a flange 4 which acts as a ground plane, and the inner conductor (i.e., the conductor 5) is extended therefrom to form a quarter wave monopole 3. Energy is fed by means of a transversely disposed coaxial line 1, 2, and quarter wave traps 7, 14 are provided in the monopole 3 and below the feed line. The higher frequency radiating element is of the second type, in which the outer conductor (an extension 8 from within the monopole 3 of the conductor) is provided with an axial half wave slot 11, a short-circuiting pin 12 being connected between the centre of an edge of the slot and the inner conductor 9. Energy is fed from below into the inner coaxial line section 10. In order to reduce ripples in the radiation pattern of the second type of radiating element, an additional slot may be provided which is opposite the other, and which is not connected to the inner conductor. The slot radiates horizontally polarized waves, and the monopole radiates vertically polarized waves. A modification is described which is intended for use on an aircraft. In this the monopole is flattened, and it and the radiating slot are embedded in a streamlined plastics fin (Fig. 3, not shown). In a second embodiment both radiating elements are monopoles (Fig. 4, not shown) and in a third embodiment both radiating elements are axial slots (Fig. 5, not shown). In a fourth embodiment the upper radiating element is a monopole and the lower radiating element is an axial slot (Fig. 6, not shown). Where the upper, higher frequency, radiating element is a monopole, a quarter-wave trap may be formed below the associated ground plane flange at the top of the outer coaxial line section, as shown in Fig. 7.
