Conformal wide bandwidth antennas and arrays

Various wideband width antennas and challenges using these antennas for conformal phase arrays are presented. Problems that arise depending on the physical separation of the antennas and corresponding separations in terms of wavelength are discussed. For conformal placement of an antennas either as an individual antenna or as in an array configuration on any arbitrary surface may require very thin antenna structures. They should be processed preferably on flexible substrates so that they will conform to the surfaces without changing the surface geometry. Archimedean slotted spiral antennas that satisfy these requirements will be used to demonstrate problems associated with UWB phased arrays.
