Abstract

Continuous transverse stub (CTS) is an antenna technology that offers greater tunable bandwidth than waveguide or patch antennas, efficiencies of over 60% and polarization isolation of 25-50 dB. This technology is also low cost, relatively insensitive to fabrication tolerance, and when combined with the ferroelectric material technology, it provides beam steering capability. For wireless communications applications, omnidirectional radiation patterns and improved feeding arrangements may also be required to further simplify the design and improve the impedance matching characteristics. To this end, we recently designed a coaxial version of the CTS technology, and experimentally verified its radiation and impedance characteristics.
