This book was released on 1969 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antenna with high gains at low elevation angles are important to long distance HF communication. With application to an 11,070-km circuit between Washington, D.C. and Asmara, Ethiopia, in view, a design for an antenna consisting of four rhombic elements in a nested-tandem configuration was proposed. The overall length of the antenna was 442.8 m (1452.6 ft), the maximum height, 73.2 m (240 ft). Its nominal operating frequency range was from 6 to 19 MHz. Power gain was computed as a function of frequency, elevation angle, and azimuthal direction. Scaled-model measurements, using 200:1 scaling factor, were carried out to verify the computations. Calculations showed the maximum gain to be 26.5 dB at 14.5 MHz at an angle of about 4.5°. The computed performance deteriorated markedly above 18 MHz. The measurements confirmed the computations at the lower frequencies and showed the deterioration in the performance near the upper frequency end to begin at a lower frequency than computer.

Book excerpt: A chart has been prepared for the design of rhombic antennae to solve simply such problems as the following: the best proportions, the angle of maximum radiation at any wave length, and the wave length of maximum radiation at any angle of elevation. The results apply only in the vertical plane contaning the principal diagonal.

Book excerpt: The report provides an account of a new rhombic antenna array design and the resultant effect upon the antenna pattern resulting from this design. The intent of this effort was twofold, first to reduce the deep nulls in the vertical profile that existed with a horizontal single rhombic in order to obtain smooth vertical coverage from 2 degrees to 24 degrees in elevation and secondly, to reduce the first side lobe levels in the horizontal plane pattern of a single rhombic antenna.

Available in PDF, EPUB and Kindle. Book excerpt: The possibility of using a logarithmically periodic, concentric, rhombic antenna array for ionospheric sounding in the HF region is considered, both theoretically and experimentally. In particular, the feasibility of simultaneous excitation of n elements within a larger, m-element array is examined in detail. For a logarithmically periodic array, the group of any n neighboring elements forms a module whose properties are identical with those of any other similar module, except for a scale factor in frequency. A mathematical representation is developed which describes the behavior of such an n-element module independently of rhombic angle and height-to-leg length ratio. The important parameters of the calculation are the number and relative sizes of the elements within the module. It is shown, on the basis of the theory, that a module of three elements having a size ratio of 1.5 to 1 between successive elements should give a considerably lower side -lobe level over a larger frequency range than is typical of the single-element rhombic antenna. A design procedure is described for arrays intended for operation over large frequency ranges. This procedure is applied to a specific case, leading to a five-element, three-module array for operation over the range 4-36 Mc. The results of radiation pattern measurements on two different antenna models are presented. (Author).
