Compact Broadband Antenna Integrated with Filter

In recent years, there has been constant growth in using gigahertz frequencies for various applications. The state of the art of antenna integration with passive circuits techniques offering increased cut-off frequencies, open up new opportunities for integrating systems along with an antenna for either Transmit/Receive application. The work carried out in this seminar mainly deals with the survey of antenna structures which are compatible to integrate with passive circuits for microwave as well as millimeter/sub-millimeter wave applications.

Lot of research in the field of passive receiver front end design is being carried out. This work covers three aspects of passive receiver front end design. The first is the analysis and design of new wide band high gain micro strip antennas, the second aspect is the design of compact high performance low-pass and band-pass filters and the third aspects is to integrate antenna and filter into single substrate. The trend of communication systems has imposed many restrictions on designers to have systems which should be light weight, robustness and have easy integration to other microwave circuits.

In most of the communications systems the receiving antenna is followed with a band-pass filter. In microwave band this is normally a distributed lter and is implemented using the transmission line resonators. The transmission line filters are not compact, and in many applications where size is an issue may not provide the best solution. In the new active arrays, for example, it is desirable to integrate a complete front end with each individual antenna element. The area allocated to each cell, however, is determined by the array design and apertures efficiency requirements and is barely integrate the antenna and band pass filter in a single module, as is it more compact may also decrease the prefiltering losses to improve the noise performance. The design of such system is a challenging task.
