Wireless communication applications of the continuous transverse stub (CTS) array at microwave and millimeter wave frequencies

The continuous transverse stub (CTS) array represents a unique class of array antenna that exploits the low-loss, low-dispersion, dimensional robustness, and design flexibility of an open parallel-plate structure as both its transmission-line and radiator basis. Relative advantages of this array type include unusually high aperture efficiencies; precision sidelobe control; benign active impedance dependence on both frequency and scan angle; and inherently low cost This paper describes and illustrate recent wideband, dual-polarized and phased-array developments of the CTS array applied to fixed and mobile terrestrial- and satellite-based broadband access applications at both microwave and millimeter-wave frequencies.
