Dielectric Sheet Mounted Dipole Antenna With Reactive Loading
US Patent:
4038662, Jul 26, 1977
Filed:
Oct 7, 1975
Appl. No.:
5/620501
Inventors:
Edwin M. Turner - Dayton OH
Assignee:
Ball Brothers Research Corporation - Boulder CO
International Classification:
H01Q 916
US Classification:
343752
Abstract:
A broadband antenna in the form of a multiple element interlaced dipole array is mounted on a thin elongated strip of dielectric material which is mechanically flexible, light weight and electrically small. Each dipole has a first tapered radiator section with an inductive loading section electrically connected to one end of the tapered radiator section. A capacitive end-loading section is connected to the inductive loading section. Second tapered radiator sections are joined to one another by a second inductive loading section. The inductive loading sections increase the effective electrical length of the first and second tapered radiators, respectively. A UHF gap filling conductor is connected to each of the dipoles to suppress grating lobes at the high-frequency end of the frequency spectrum received by the antenna. The two tapered radiator sections of each dipole are connected to one another by a pair of conductors which are tapered away from one another toward the output terminals of the antenna to provide a preselected output impedance to a receiver.
