Abstract :
A novel combination of a microstrip patch and dielectric sphere is described. Measurements and analysis illustrate the basic action and the use of this new element in a millimetre-wave array. Improved radiation pattern control and sparse deployment of elements, at a cost of some increase in antenna depth and constructional detail, are the main features identified.
