1,020,727. Aerials. H. KOLBE, and H. KOHLER. July 9, 1963 [Feb. 14, 1963], No. 27176/63. Heading H4A. A dipole aerial for operation at a higher and a lower frequency band is formed with two inductors 3 and 4 each disposed one half-wavelength at the higher frequency from a respective one of two feed points 2 so that the end sections 10, 11 are isolated at the higher frequency but coupled at the lower frequency by the impedances presented by the inductors. The dipole may be folded, Figs. 1 and 2 (not shown). |
