Abstract

921,950. Aerials. C. GALLO. June 20, 1961, No. 22324/61. Class 40 (7). An aerial circuit comprises a loop aerial in series with a tuning capacitor and an inductive coil arrangement, the coil arrangement having a ferrite core. The coil arrangement may comprise several coils in parallel. In parallel with the series circuit there may be provided a further coil mounted on a ferrite core, Fig. 2, or a capacitor, Fig. 4. The inductive coil arrangement may comprise a single coil which is connected to the transmitter or receiver via a tapping point, Fig. 6. The aerial has wideband characteristics and has a high impedance.
