Abstract:
The need of miniaturization in the present day communication industry is
challenging. In the present scenario, printed antenna technology is highly
suitable for wireless communication due to its low profile and other desirable
radiation characteristics. Small monopole type antennas are overruled by
compact small antennas for present day mobile communication applications.
Coplanar waveguides (CPW) are printed on one side of a dielectric
substrate. CPW have attracted the attention of antenna designers due to their
excellent properties like ease of integration with ‘MMIC’, low cost, wide
bandwidth, flexibility towards multiband operation, low radiation leakage and
less dispersion. The requirement of omnidirectional coverage, light weight and
low cost made these CPW fed antennas a good candidate for wireless
applications. The main focus of the thesis is the study of coplanar waveguide
transmission line. Rigorous investigations were performed on both the ground
plane and signal strip of a coplanar waveguide transmission line to create
effective radiation characteristics. Good amount of works have been done to
transform CPW line to antenna suitable for mobile phone applications
