Book Description
As a result of a 10-month study funded by the Air Force Space and Missile Systems Organization and carries out by ESSA's Institute for Telecommunication Sciences, four UHF antennas were designed and their gains versus elevation angle up to 45° and horizontal plane patterns for a 5°elevation angle were measured with each antenna buried beneath 1 m of refractory concrete. Techniques were developed and used to measure loss tangent and dielectric constant of plane ground and large samples of refractory concrete versus drying time and temperature. Theoretical studies of buried annular slots, buried antenna patterns, encapsulant geometry, and dielectric-coated linear antennas paralleled the measurement effort.
