A New Dual-Loaded Aperture Probe for Near-Field Millimeter Wave Imaging
Millimeter wave differential probes have demonstrated great potential for high-resolution near-field imaging and detection of small and low scattering targets. There are several differential probe designs that already exist each with own advantages and disadvantages. An alternative design, using switchable loaded elliptical slot antennas placed on a standard waveguide aperture is proposed. The proposed probe provides higher image resolution in a much smaller form factor (i.e., overall size). This design is compared to prior designs of differential probes through simulation and measurements.
