Parasitic loop counterpoise antenna

Claim 2

An antenna system comprising a counterpoise in the form of a conducting metal surface, a radiator element for radiating electromagnetic radiation positioned above said counterpoise, and parasitic means comprising a plurality of circular loop elements positioned above said radiator element so that said radiator element is intermediate said parasitic means and said counterpoise and positioned in cooperative relation thereto as a function of the frequency of radiated energy.

Claim 3

The device of claim 1 in which said circular loop elements are successively stacked above said radiator element so that said circular elements share a common longitudinal axis with said radiator element.

Claim 4

Although the characteristic curve is mild in gradient than that of the solid electrolyte obtained in Example 1, this solid electrolyte is superior to the conventional one as may be readily appreciated upon comparison with the curve 1 representing the characteristic of the latter. Examples 3 to 8 Solid electrolytes were produced in the same manner as in example 1 but by mixing CeO2, Gd2O3 and MgO in the proportions shown in table 2 below. These solid electrolytes had pecific resistance--temperature characteristics as shown in FIG. 3 respectively.

Claim 7

The device of claim 1 in which said circular loop elements are concentric about a central circular element positioned above the radiator element to that said circular elements are located in the same plane and share a common longitudinal axis with said radiator element, the mutual spacing of said circular elements and the spacing of said elements relative to said counterpoise and said radiating element relative to said counterpoise being a function of the frequency of radiated energy. FIG. 10 is a sectional view of an oxygen refiner in which the solid electrolyte according to the present invention is used; and FIG. 11 is a characteristic curve of the oxygen refiner, showing the relationship between the effluent rate of produce oxygen and the voltage. DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to FIG. 1, the characteristic curves show the relationship between the composition of the electrolyte of this invention, consisting essentially of 2 mols of CeO2, x mol of Gd2O3 and y mol of MgO, and the specific resistance of the electrolyte at specific temperatures. The curve 1 is curve on which the electrolyte shows a specific resistance of 80 Omega cm. at 725* C., and the region inside of the curve is a region in which the electrolyte shows a specific resistance smaller than 80 Omega cm. and the region outside of the curve is a region in which the electrolyte shows a specific resistance larger than 80 Omega cm. The curve 2 is a curve on which the electrolyte shows a specific resistance of 30 Omega cm. at 800* C. and the region inside of this curve is a region in which the electrolyte shows a specific resistance smaller than 30 Omega cm. Namely, this curve epresents an electrolyte which is superior to thaT represented by the curve
