Over the last twenty years Corrugated horns have become widely used as feeds for microwave reflector antennas because of their high efficiency, good pattern symmetry and low cross-polarisation. They are increasingly used in antennas for satellite communications, radar, microwave point to point communications and radio astronomy.

In the past few years, the concept of creating microwave antennas using microstrip has attracted increasing attention and viable practical designs are now emerging. The purpose of this monograph is to present the reader with an appreciation of the underlying physical action, up-to-date theoretical treatments, useful antenna design approaches and the overall state-of-the-art situation. The emphasis is on antenna engineering design, but to achieve this goal it has been necessary to delve into the behaviour of microstrip in a much wider sense and also include aspects of electromagnetic analysis. As a consequence, the monograph will also be of interest to microstrip circuit designers and to some extent those seeking electromagnetic problems of a challenging nature.

Microwave Antenna Theory and Design is an unabridged reprint of the book published by McGraw Hill, as Volume 12 of the MIT Radiation Laboratory Series in 1949. The Editor of the Volume, the late Professor Samuel Silver, contributed extensively to the text and subsequently became one of the best known people in the world of radio science.

The subject of antenna measurements is one which has undergone revolutionary changes in recent years, in particular within space applications, where high demands are placed upon antenna design and construction.
