A new analysis of the sandwich-wire antenna

It is hypothesized that the exact shape of the center conductor of a sandwich-wire antenna, provided it is of fairly simple form, is not important in determining the radiating properties of the antenna. An analysis is therefore made by standard principles of a sandwich-wire antenna having a particularly simple shape for the center conductor. This approach leads to an explicit formula for the structure attenuation constant in terms of its geometrical parameters which may be used for design purposes. Experimental measurements which support the theory and justify the shape-independence hypothesis are presented.
