Abstract

856,889. Printed strip transmission lines. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Feb. 19, 1959 [June 11, 1958], No. 18731/58. Class 40(8). A transmission line comprises three parallel conductors 1, 2, 2 printed on the same side of an insulating support 3. The outer conductors may be grounded and are at least three times the width of the central strip. The width of the gaps between the conductors determines the characteristic impedance of the line and is of the order of 1 / 1000th. of the working wavelength. Connection to the line may be made through a bolt inserted through the aperture 4. The line is shown terminated by a printed inductor 5.
