Abstract:

The federal communication commission releases 7.5 GHz (From 3.1 GHZ to 10.6 GHz) bandwidth for Ultra-wideband wireless communication , UWB is rapidly advancing as a high data rates wireless communication technology and the micro strip antenna are often realized with bandwidth of the order of 1% to 5% . Bandwidth enhancement techniques are one of the areas of research in the field of micro strip antennas. Basically the bandwidth is defined as a percentage of width of the range of acceptable frequencies and the resonant frequencies of the antenna. The parameter such as radiation efficiency return loss and voltage standing wave ratio (VSWR) are often used to define the bandwidth o a micro strip antenna. To choose an optimum antenna for ultra-wide band several factor must be taken into account including physical profile, compatibility and bandwidth, radiation efficiency and radiation pattern. The main challenge in UWB antenna design is achieving the very broad bandwidth with high radiation efficiency and small size. Many techniques the impedance bandwidth of small antennas and to optimize the characteristics of broadband antennas have been widely investigated and in various published papers as listed in this survey paper.
