With a total of 2 patents to his name, Blunden's work showcases his innovative spirit and technical expertise.
Latest Patents
Among his latest patents is the Doppler microwave sensor, designed for vehicle alarm systems. This sensor employs a mixer stage and a signal-processing stage on a printed circuit board. The board features a ground plane with a slot antenna, which is coupled to the mixer stage. The ground plane is electrically connected to a conductive enclosure that houses the mixer and signal-processing components. Additionally, a dielectric lens may be placed over the slot antenna to optimize the transmission beam pattern for the specific vehicle. The mixer stage utilizes a self-oscillating mixer arrangement, with a bipolar transistor as the active element, allowing a single antenna to transmit the oscillator signal and receive the Doppler-shifted return signal.
Another significant patent is the moving vehicle transponder, which operates in the UHF range. This transponder tag includes a substrate of dielectric material with a conductive surface that forms a ground plane and a dipole antenna. A slot line within the ground plane creates a balanced antenna feeder leading to the dipole antenna's center. The substrate also features a transmission line feeder for electromagnetic coupling with the slot line, which connects to a transceiver circuit and processing circuit for transponding functions.
