The first edition of Antenna Theory and Design was published in 1981 and the second in
1998. This three-decade span has seen major expansions of antenna application areas,
mainly in wireless communications. Along with technology advances has come public
awareness of the presence and importance of antennas. Base station antennas are now
visible in all urban and rural areas. Wireless telephones such as smart phones have
put antennas into the consumer’s hand. Personal and fleet vehicles have many wireless
features such as satellite navigation (e.g., GPS), satellite and broadcast radio, cellular
telephone, remote keyless entry, wireless toll tags, remote tire pressure monitoring, and
many more.
This third edition has 16 chapters, which is an increase of 4 chapters over the second
edition, representing both introduction of new material and reorganization of previous
topics. The third edition has several new sections of material specifically addressing
modern wireless applications for antennas. Chapter 11 on low-profile antennas and personal
communication antennas includes an expanded treatment of microstrip antennas
and arrays, and new material on leaky wave antennas, fundamental limits on antenna size,
antennas for compact devices, radio frequency identification (RFID) antennas, dielectric
resonator antennas, near fields for large antennas, effects of the human body on antenna
performance, and biohazards of RF exposure. |
