Abstract
The reduction of foreground reflection into a vertically polarised 1000 MHz u.h.f. low delta aerial using a half-wave resonant slot in a one-quarter-wavelength-wide conducting flange is examined. The impedance, radiation efficiency and polar-diagram characteristics of a slot in limited conducting planes are presented. Procedures to optimise a slot to complement the Yagi-type array of vertical monopoles are described, and the application of such a slot to a 21.840 MHz h.f. aerial in Townsville, Australia, is discussed.
