Download or read book Computed Radiation Patterns of Log periodic Antennas Over Lossy Plane Ground written by Mark T. Ma and published by . This book was released on 1967 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four different orientations of a log-periodic dipole array of 11 elements over several types of ground are studied. With the xy-plane always treated as the flat ground, they are called 1) the x-array when dipole elements are parallel with the x-axis and the array axis is parallel with they-axis, 2) the y-array when dipoles are parallel with the y-axis and the array axis is coincident with the z-axis, 3) the z-array when dipoles are parallel with the z-axis and the array axis is parallel with the y-acix, and 4) the z=Ay=array when dipoles are parallel with the x-axis and the array axis makes an angle with the z-axis.

This book was released on 1968 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two models of log-periodic dipole arrays over several types of ground are studied. The total field above the ground is computed and plotted for each ground with frequency, array height, and orientation of the array as the varying parameters.

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical power-gain formulas for 13 different antenna models above a flat homogeneous lossy ground are derived in terms of frequency, antenna geometrics, and ground constants. The radiation resistance required in the formulation is calculated with an assumed sinusoidal current distribution.

Available in PDF, EPUB and Kindle. Book excerpt: A theoretical method is formulated to calculate input and mutual impedances, total field radiated, and power gain of a Wullenweber antenna above a lossy flat earth. The Wullenweber antenna considered here is essentially an array of two concentric rings of discrete elements. Each ring is placed in front of a concentric screen. The inner ring is designed to operate at 3-10 MHz white the outer ring is at 8-32 MHz. The radiator used for the high-band ring is a sleeve antenna, and that for the low-band ring is a three-wire folded monopole. Numerical results are given as a function of frequency, ground constants, elevation and azimuth angles with a specified set of element and array dimensions.
