Abstract

1532010 Omnidirectional antenna arrays THOMSON-CSF 4 Feb 1976 [7 Feb 1975] 04456/76 Heading H4A An omnidirectional antenna array comprises at least two independent omnidirectional antennas arranged one above the other on a common axis of symmetry and connected to concentric, coaxial feeder lines extending at the array centre along said axis of symmetry. In the Fig. 2 embodiment conductors 1 and 2 are the feeder for cylindrical folded dipole elements 11 and 12; conductors 2 and 3 are the feeder for elements 14 and 15. Traps 10 and 13 are connected to conductors 1 and 2, trap 13 providing decoupling of antenna 11, 12 from antenna 14, 15. Two biconical antennas 21, 22 and 23, 24, and two discone antennas 31, 32, and 33, 34 respectively constitute the array in the Fig. 3 and 4 embodiments. The two antennas may operate on different frequency bands, and are capable of wideband operation. The axial feed arrangement ensures that the omni-radiation pattern is not distorted by obstruction by the feeder lines. The array is useful on an aircraft.
