ANTENNA Filed Ju ne 3, 1930 INVENTOR ALBRECHT GOTHE BY WQQ ATTOR N EY Patented May 16, 1933 UNETED STATES PATENT OFFICE F'UR DRAH'ILOSE TELEGRAPHIE, M. B. H., OF BERLIN,
OF GERMANY GERMANY, A CORPORATION ANTENNA Application filed. June 3, 1930, Serial No. 459,087, and in Germany June 6, 1929.
In the operation of antennae for transmitting or for receiving electromagnetic waves recourse is often had to what is known as an energy feed or lead line for the transfer of energy between the transmitter, or the receiver, on the one hand, and the antenna, on the other hand.
A case of this kind is illustrated in Figure 1 where parts 1 designate the radiator, while the energy feed line or lead is denoted by numeral 2. However, an energy line of this i kind is liable to exhibit disagreeable secondary effects in so far as it tends to disturb the desired propagation of the radiation field. According to this invention, therefore, the radiating antenna part has the form of a tube or funnel wide at both ends, while the energy feed line is disposed inside the radiating antennae parts and is connected at the desired feeding points.
In the accompanying drawing, Figure 1 illustrates, as already indicated, an old type of lead in line to an antenna, and
Figures 2 and 3 illustrate according to my invention a novel lead arrangement for an antenna,
In one embodiment of the invention as shown by way of example in Figure 2, where again 1 denotes the radiating antenna parts,
I claim:
1. An antenna system comprising a pair of physically separated and electrically unconnected coaxial conductive radiating cylinders, and a two wire linear transmission line for supplying energy to said cylinders, said two wire line being mounted within and coaxial to one of said cylinders, one con- 0 ductor of said two wire line being connected to one end of one of said cylinders, and the other conductor of said two wire line being connected to the adjacent end of said other conductor cylinder.
2. An antenna system as defined in claim 1, the coaxial conductive cylinders being arranged vertically.
8. An antenna system as claimed in claim 1 the coaxial conductive cylinders being arranged horizontally.
4:. An antenna system comprising a pair of coaxial conductive radiating cylinders arranged end to end, said cylinders being physically separated from each other and unconneeted, and a two wire transmission line for supplying energy to said cylinders, said two wire line being mounted within one of said cylinders, one conductor of said two wire line being connected to one end of one of said cylinders and the other conductor of said two wire line being connected to the adjacent end of the other conductor cylinder.
ALBRECHT GOTHE.
