Gupta, R: Multilayer Directional and Planar Omnidirectional

Antennas are the fundamental component of any wireless communication system. The ubiquity of wireless communications has spurred the development of an extraordinary range of antennas of different shapes and sizes suited for different applications, each with its own advantages and limitations. Wireless communication,nowadays,is not meant merely to communicate and cover large distances, but rather for its flexibility and comfort. Short-range wireless links provide access to the fixed telecommunication infrastructure. There are applications especially in short range wireless link where omnidirectional antennas are required, however, a highly directive and efficient antenna is a necessity in long range wireless applications.Regardless of the application, every system demands increased functionality, better performance, reduced size and most importantly lower development cost.
