UWB technology has received an impetus and attracted academia and industrial attention in the wireless world ever since Federal Communication Commission released a 10dB bandwidth of 7.5 GHz (3.1-10.6 GHz) with an effective isotropic radiated power (EIRP) spectral density of - 41.3 dBm / MHz for communication applications. Since February 2002, the release of an extremely wide spectrum for commercial applications has generated a lot of interest in the research and development of UWB technology for various applications. An UWB antenna should have omnidirectional radiation pattern, S11 less than equal to -10 dB over the entire frequency band and a good impulse response with minimal distortion. This book focuses on design and analysis of planar UWB antennas, band-notched UWB antennas, integrated Bluetooth and UWB antennas, integrated Bluetooth and WiMAX/WLAN band notched UWB antennas for wireless communication. The proposed antenna structures offer attractive advantages such as low cost, light weight, high efficiency, ease of fabrication, low cross polarization; stable gain, small group delay variation and its radiation patterns indicate its suitability for UWB applications.
