INVESTIGATIONS ON MULTIBAND BEHAVIOR OF MICROSTRIP ANTENNAS

Microstrip antennas have become popular in the advent of cellular communication
technology due to their compact size, light weight, ease of fabrication, reliability, and
thin profile that makes their mounting conformal. If a single antenna can be used for
multi frequency operation, the complexity of the mobile communication antenna
system could be reduced.
Exploiting the frequency reuse and smart antenna characteristics could result in cost
reduction and enhancing the communication quality and range. The foreseen potential
ofthese aspects ought to be further explored and studied for future benefits and hence,
has led to the proposal of this project entitled "Investigation on Multiband Behavior
ofMicrostrip Antenna".
The objectives ofthe project are to familiarize with the concepts of microstrip antenna
and to analyze the multi band behavior of microstrip antenna in terms of the multiband
characteristics, frequency separation of bands, resonant frequency dependency on
dimensions and slot positions, and the effect of feed location on the antenna behavior.
The project work would analyze typical rectangular microstrip antenna structures by
modeling and simulating the antenna structure using HP High Frequency Structure
Simulator (HP HFSS) software and to conclude on the findings.
