The concept of radiation from microstrip antenna was proposed about
three decades ago. Because of numerous advantages of these antennas over
the conventional microwave antennas like light weight, low cost, low
volume, planar structure, conformability to any surface, and
compatibility with integrated circuit and solid state devices, such
antennas are of great interest for a diverse range of applications in
terrestrial and satellite communications systems. One of the interesting
features of microstrip antennas is that they are capable of radiating
power in linear as well as circular polarization mode. Recently, the
development of a microstrip antenna with dual-band and dual polarization
features has drawn considerable attention to the scientists and
engineers for its important applications in SAR systems, mobile
communications etc. The research interest of the author is thus focused
on the development of such microstrip antennas for dual-band operations.
The design and development of various microstrip antenna structures with
dual-band operation capability has been discussed in this monogram.
