“…Adjacent spirals of paired polarizations with connecting arms will develop dual polarization [45] capabilities of spiral arrays. These types of low profile planar array elements [46][47] suffer from impairment in bandwidth when elements are placed close to the ground structure. To reduce the ground plane effects in antennas, Electronic Band Gap (EBG) structures [48] are introduced.…”

Ultra-wideband (UWB) phased array antennas are more essential for radar, communication and EW applications. Systems can operate over wide band coverage. The high gain systems require wideband, wide angle scanning, good radiation pattern and returnloss over multioctave bandwidth. This review discusses the problems present in this system, which include mutual coupling, grating lobe rejection, active return loss, gain fluctuation with scanning, and multiple beam generation. In this, the aperture size of the array is limited by the overall gain requirement of the system. On the other hand low gain systems require wideband with good radiation pattern and axial ratio. Here the matching over wideband is simpler as it depends on broadband balun configuration. This system has limited bandwidth over scan angles. These antennas more preferred as wearable antennas in communication applications. This paper mainly discusses the existing UWB phased array antennas such as Vivaldi Arrays, All-Metal Arrays, Spiral Arrays, Sinuous Arrays, and Coupled Arrays. This review paper presents a correct direction for selecting the type of antenna in terms of impedance bandwidth, gain, and materials influencing antenna performance, suited for different applications.
