Characterization of Microstrip Patch Antenna Array for Ultra Wideband UWB Applications

Abstract

This thesis is involved with the modelling, simulation, and experimental work on single and multiple elements, i.e., antenna array characterization in a microstrip antenna, as well as various types of design and manufacturing of single and array microstrip antennas. The purpose of this thesis is to study how the characterization performance of the microstrip patch antenna array evolves on several parameters of the MPA (microstrip patch antenna). For more than a century, people have been investigating radio waves, which are electromagnetic phenomena that send signals through the air. newline Since then, a number of resonant antenna approaches, such as the microstrip patch antenna, have been introduced. Gain, directivity, and polarization were usually given more importance than the extension of bandwidth, since with a fractional bandwidth of only a few percents, antenna impedance-bandwidth performance was never a concern before. However, with today s UWB need the bandwidth of antenna can be a bottleneck for wireless communication system. newline newline The frequency band (3.1 GHz-10.6 GHz) of antenna is worthy for UWB (Ultra-wideband) and broadband utilizations like wireless communication, defense, satellite communication, GPS (global positioning system), RF devices, WLAN/WI-MAX utilizations. Ultra-wideband is an emerging technology that offers a new paradigm for the allocation and use of the radio spectrum. UWB is a wireless approach for transmitting digital data at a very high speed, which utilizing minimum transmission power. newline
