To the memory of Professor J. R. James, who unfortunately passed away at
the planning stage of the third edition of Mobile Antenna Systems
Handbook (MASH). Professor James greatly contributed to the first and
secondeditionsofMASHasacoeditorandoneofthecoauthors.ProfessorJames
is well known as a pioneer of printed and microstrip antennas. His death
leaves us with a large scientific, technological, and personal void, but
the rich heritage he has left is of inestimable benefit to us. His pioneering
work stimulated the further study and development of printed antennas and
microstrip antennas and encouraged the creation of various types of planar
antennas, which are particularly significant in mobile systems where
small, compact antennas are required.
