Latest Patents

Ed Pachal holds a patent for an omni-directional planar antenna design. This invention features an omni-directional, planar folded dipole antenna and a related quadrature phase shifter implemented on printed circuit boards (PCBs) with differing properties that are perpendicularly engaged. The planar antenna segment is designed on a single-sided, inexpensive PCB, while the quadrature phase shifter and system electronics are implemented on more expensive multi-layer PCBs. This design reduces costs and improves system reliability by eliminating the need for coaxial or similar connectors of varying material and installation quality between the planar antenna and the quadrature phase shifter. The planar antenna transmits radio frequency signals in an omni-directional pattern and can receive signals from remote dipole antennas positioned in arbitrary physical orientations. The quadrature phase shifter not only provides phase shifting functions but also converts an unbalanced radio frequency transceiver output signal into a balanced input signal for the planar antenna.
