Dual polarised sinuous antennas - Google Patents This invention relates to wide bandwidth sinuous antennas with two orthogonal senses of polarization and particularly to sinuous antennas with both senses of circular polarizations, and more particularly to dual circularly polarized sinuous antennas with pattern, gain, impedance and bandwidth properties similar to the singly circularly polarized Archimedes and log-spiral antennas.

Gain, usually expressed in decibels, indicates how well the antenna focuses energy from a particular direction, in comparison with a standard reference antenna (an antenna with known performance, used to calibrate other or developing antenna technologies).

Gain-intensified slot antennas backed by SIW cavity using… Gain-Enhanced SIW Cavity-Backed Slot Antenna with Arbitrary Levels of Inclined Polarization.In this paper, a gain-increased method of cavity-backed slot antennas based on excitation of high-order substrate-integrated waveguide cavity resonance has been proposed. High Gain Compact Strip and Slot UWB Sinuous Antennas...… Three ground-backed compact strip-and slot-sinuous antennas are analyzed. Proposed configuration allows for a single lobe, polarization-versatile, high efficiency, and ultrawide band antenna not needing a cumbersome lossy back cavity typical of conventional single-lobe sinuous antennas. Simulated gain patterns of the SIW cavity-backed slot …
