Ultra-wideband is a radio technology invented by ‘Robert A .Scholtz and others that for an short range
and high bandwidth communication of the radio spectrum can use a very low energy level.The ultra-wide band
antennas are applied where larger bandwidth for the transmitting signal is needed. Wide bandwidth in the range from
500 MHz to the frequencies above 8000 MHz are covered by ultrawideband antennas. It is a wireless technology which
uses very low power for short distances and transmits large amount of digital data over a wide spectrum of frequency
bands. In this paper, a review of various techniques to realize ultra wide band micro strip antennas (MSA) is presented.
By using different techniques like basic planar monopole antenna and the variations of the same by using different
shapes of radiating monopole antenna, like, bi-conical, Bowtie, etc. these antennas are realized.
