    The 150-foot slotted waveguide antenna for operation on a wavelength of 10 centimeters at the National Research Council, Ottawa, Canada, is now in operation as one element of an interferometer. The other element is itself a simple interferometer with element separation equal to that of the long array and is placed to the west on the common E-W axis. A rotary phase shifter in the arm between the ar... View full abstract»

    Measurements were carried out on 6.4-cm. and 17- cm wavelength on two optical paths, 54-km and 82-km long, stretching over sea nearly East-West and starting at the same point. For the greater part of the measurements, height-spaced receivers were used. The bulk of the statistical data comprises distributions of field strengths for every day of measurement. Curves for single receivers and diversity... View full abstract»

    3000-mc signals from a rotating narrow-beam transmitting antenna have been observed at distances from 92 to 177 miles. The manner in which the received power builds up and falls off as the transmitting beam sweeps past the receiver shows a variety of shapes instead of merely reflecting the transmitting-antenna patterns as would be expected on a line-of-sight path. From a series of these received-p... View full abstract»

  • Back-scattering cross section of a thin, dielectric, spherical shell

    The back-scattering cross section of a thin dielectric, spherical shell is calculated on the basis of simplified boundary conditions at the shell. These conditions approximate the correct conditions at the shell better, the higher the dielectric constant of the shell, and the less the variation of the normal component of the electric field along the surface of the shell. Numerical results are adde... View full abstract»

  • Serrated waveguide--Part I: Theory

    A corrugated waveguide in which the corrugations pierce the broad wall, permitting leakage, is called a serrated waveguide. Controlling the size and spacing of the serrations will permit the design of a practical traveling-wave antenna. In this paper, an analysis is presented for the case of serrations which have a transverse dimension equal to the width of the broad wall, and longitudinal dimensi... View full abstract»

    Groups of nonresonant closely-spaced slots, cut in the broad wall of a rectangular waveguide, have been studied in a series of experiments. The name "serrated waveguide" has been applied to such structures. The complex propagation constant of the fundamental mode in a serrated waveguide has been measured as a function of slot size and spacing. The results have been used in the design of traveling-...

    This paper describes a technique for controlling the radiation from a dielectric rod waveguide by placing obstacles or antenna elements at appropriate points along the waveguide. The HE_{11} mode on a dielectric rod was used to excite concentric rings and radial wires. The coupling of the obstacles to the HE_{11} mode ... View full abstract»

  • A circularly-polarized corner reflector antenna

    Unidirectional, circularly-polarized radiation may be obtained by tilting a dipole in a corner reflector. Inherent advantages of this antenna are the simplicity of both the construction and adjustment. The theory of images is employed to develop the basic theory of the antenna for the cases of greatest practical interest. An experimental investigation has been made on the radiation characteristics... View full abstract»

    This paper is concerned with the determination of corner reflector characteristics for reflectors of arbitrary apex angle excited by any infinitesimal dipole source which is tangent to a circular cylinder having the reflector axis as its axis. Use is made of the dyadic Green's functions for the perfectly conducting wedge recently given by Tai, and the results are obtained as infinite series of Bes... View full abstract»

    The expression is developed for the mutual impedance between two staggered parallel center-fed, infinitely thin antennas of unequal lengths, Heretofore unpublished curves are presented here which display the mutual impedance characteristics for a variety of unequal antenna lengths in echelon.
