v Specification of Letters Patent. Patentd May 2 1-, 1921.
Application filed September 16, 1919. Serial No. 324,228.
To all whom it may concern:
Be it known that we, STANTON C. Hoornn and GEORGE H. CLARK, citizens of the United States, residing at Washington, in the District of Columbia, have invented an Improvement in Radio-Receiving Antennae, of which the following is a specification.
The present invention relates to radio re ceiving antennae and particularly to a multiple antennae system having for its purpose the eilicient reception of long distance radio telsgraphic and telephonic communications.
1 eretofore it has been proposed to utilize a pluralit of antennae spaced a distance apart so tiat the incoming electro-ma netic waves impinge thereon at different p ases, the energies of the various antennae being collected through the agency of a series of tuning inductances associated with a radio signaling receiving apparatus.
. Great difiiculty has been encountered in attempting to connect the radio signal receiving apparatus to a number of separate electro-magnetic wave collecting systems or antennae. This difficulty is due to the inherent capacity existing between the ground and the connecting wires joining the wave collecting systems with the radio signal recciving apparatus.
The object of the present invention is to obviate the diificnlties above enumerated and to provide means for greatly increasing the audibility or intensity of signals received when employing a plurality of associated antennae.
Our invention will be more fully understood by referring to the annexed drawings which accompany and form a part of this specification and in which like characters of reference have been used to indicate similar parts throughout the several drawings.
Figure 1 illustrates diagrammatically the arrangement of the multiple antennm conductively connected at their elevated extremities and individually grounded.
Fig. 2 shows a plurality of antennas as illustrated in Fig. l. but conductively connected at both the elevated and lower extremities. i
With particular reference to Fig. l, mu morals 1, 2, 3 and 4 are applied to individual elevated electro-magnetic wave collecting systems or antennae having tuning inductances 5, 6, 7 and 8 together with variable condensers 9, 10, 11 and 12 inserted in 'each antenna circuit and connected to the ground 13. The elevated antennae are con-- ductlvely connected as indicated at 14:. We desire to point out that in this conductive connection of the individual antennae resides the successful and eiiicient operation of the multiple antennae system as an electromagnetic wave collector. dio slgnal responsive apparatus is connected to tho tuned secondary circuit 15 inductively associated with primary inductance 8 positioned in the antennae system l. Fig. 2 illus trates a modification of the radio signal recalving system shown in Fig. 1, wherein the antennae are conductivelv connected at the lower as well as at the elevated extremities. The conductor 16 is employed to c0nductively connect the antennae system in lieu of earth connection as in Fig. 1..
In the operation of the antennae system the individual antennae 1, 2, 3, and 4 are spaced Standard rapreferably a half wave length apart with the received energy into intelligent signals. Having thus described our invention, What,
We claim and desire to secure by Letters Patent of the United States is:
1. In a radio telegraphic and telephonic receiving system, the combination of a plurality of antennae located at approximately equal distances apart on a line bearing in the direction of the distant transmitting station, means for tuning to resonance each antenna to the incoming wave length and a conductive connection joining the elevated extremities of said antennae, the lower eX- tremities of which are grounded and means for integrating the increments of energy collected by the individual antennae in a receiving apparatus substantially as described.
2.
