ANTENNA.

Application filed July 9,

body and transmitted to a radio receiving setp Another object of the invention is the provision of an antenna of this character, wherein the body of the same is of novel form and construction, as it is in the form of an inverted saucer with a companion non-inverted lower portion made a part thereof, which together with the body serves to enclose a series of superposed disks of metal or other conducting material, these being insulated from each other and act as condensers for the high frequency electric currents picked up by the body, the entire assemblage being supported by a standard or post, which has means for attachment thereto of a lead-in wire to a radio receiving set for transmitting the ether waves thereto.

A further object of the inventionis the provision of an antenna of this character, where- 30 in the construction thereof renders it nondirectional and when in use with a radio set of the receiving type enables the latter to be more selective and operate with greater effic-iency than would be obtained if the present known or used types of non-directional antennae were employed.

A still further object of the invention is the provision of an antenna of this character, which is extremely simple in construction, strong, durable, thoroughly reliable and eiiicient in its purpose, readily and easily mounted for use with dispatch, and inexpensive to manufacture and install.

Other objects will be in part obvious and in part hereinafter pointed out.

The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawing, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding of the same.

In the accompanying drawing Figure 1, is a top plan view of the antenna constructed in accordance with the invention.

1925. Serial No. 42,398. I

Flgure 2, is a sectional view taken on the.

line 22 of Figure 1, looking in the direction of the arrows.

F1gur e 3, 1s a fragmentary enlarged sed tional view taken approximately on the line 22, look ng in the direction of the arrows 3-3, of Figure 1.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the

antenna A, as a unit comprises an umbrella shaped or inverted saucer like top section 5,

of conducting material, preferably copper. although it may be made from any other suitable material forrollecting high fre-" quency electric currents, the diameter of said section being of the required dimensions as the occasion may demand. while within the convexed hollow 6, of this top section 5, is centrally located a smaller non-inverted saucer shaped bottom section 7, which is likewise made from conducting material for electric currents, and the edge of this bottom section abuts and is soldered or otherwise secured to the inner surface of the top section 5, to form a unitary structure. A

These top and bottom sections 5, and 7, united as before named forms a chamber 9. therebetween, andv passed upwardly through the bottom section 7, ccntrallv thereof is a hollow or tubular post 10. the upper end being soldered or otherwise secured centrally to the top section 5. while the lower portion of this post extends the desired'distahce beneath the bottom section 7, the latter being also soldered or otherwise fastened to said post.

The lower end of the post 10. is suitably fitted in an insulator 11, preferably of mica. although it may be of othernon-conductine, material. It is to be understood that this insulator 11, is fastened to any suitable support (not shown) upon a foundation or other part where it may be required to erect the antenna for use with a radio set of the receive ype.

Carried by the post below the bottom section 7, is a binding device 15 for the lead in wire of the radio set and in this manner the antenna is hooked up, therewith.

Arranged within the chamber 9. formed by the top and bottom sections 5, and 7, are a series of disks 12, made from metal, and these disks are spaced apart by the inter-post tioning of sheets of insulation 18, therebetween. The disks are fitted tight about the post 10, and certain of the outer disks 12, are of less diameter than the intermediate disks, so that the group will conform to the interior shape of the chamber 9, by reason of the curved surfaces of the top and bottom sections 5, and 7, of the antenna.

The top and bottom sections 5, and 7 are formed or have struck therefrom annular reinforcing ribs 14, to give strength. to the an.- tenna and torender the sections rigid.

The disks 12, in their arrangement serve to efliciently collect the ether waves and send the same down through the post 10, to be transmitted through the lead-in wire to the radio receiving set.

What is claimed is:

1. An antenna of the character described, comprising a body forming a. chamber, a. post extending centrally into said chamber and fastened to said body, and a series of metal plates within'the chamber, and insulations disposed between said plates, said plates snugly embracing the post.

2. An antenna of the character described, comprising a body forming a chamber, and

chamber and fastened to the top, and a series of plates within thechamber and snugly em- I bracing said post, said plates being arranged in spaced relation to each other.

3. An antenna of the character described, comprising an inverted saucer shaped top section made from material conducting to high frequency electric current, a non-inverted saucer shaped bottom section made from conducting material and of less diameter than the top section, arranged within the latter and made fast thereto centrally of the same, a post extending centrally through the bottom section and having its upper end fast to the top section, av series of metal disks between the top and bottom sections, spaced from each other and snugly embracing the post, an insulator mounting the lower end of the post, and a binding device on the post above the insulator for attaching a lead-in wire thereto.

In testimony whereof he afl'ixes his signature.

WILLIAM HENRY HAWORTH.
