Latest Patents

Chapman holds a patent for a "Compact cavity-backed discone array." This invention features a compact shallow cavity-backed discone antenna array designed for conformal omnidirectional antenna applications. The antenna array consists of multiple discone antennas arranged in a ring array within a circular contoured conical cavity. The cavity is protected by an electrically transparent radome. Each discone antenna element is fed using coaxial transmission lines. The performance of this design has been validated through simulations and experiments, demonstrating excellent reflection coefficients and omnidirectional gain radiation patterns across a frequency range of approximately 960 MHz to 1220 MHz. Notably, this shallow cavity-backed discone antenna array can be utilized as a flush-mounted antenna that conforms to the outer mold line of an aircraft.
