Abstract: A resonance structure includes a conductor part that expands along a first plane including a first direction and a third direction; a ground conductor that expands along the first plane; first pair conductors that electrically connect the conductor part and the ground conductor along a second direction intersecting the first plane and face each other in the first direction; and second pair conductors that electrically connect the conductor part and the ground conductor along the second direction and face each other in the third direction. The conductor part capacitively connects the first pair conductors and capacitively connects the second pair conductors. A first edge and a second edge of the conductor part intersect with each other. The first edge extends in the first direction from one conductor of the first pair conductor. The second edge extends in the third direction from one conductor of the second pair conductors.

Abstract: An improved Ground Penetrating Radar (GPR) system is provided. The system advantageously employs full waveform digitization of a returning signal to significantly reduce the number of launch signals and allowing the amount of radiation emitted to stay within the limit set by the Federal Communications Commission (FCC), while producing a robust information detection signal. In addition, intermittent large latent-duty-cycle sampling employs a less expensive digitizer typically used in prior art GPRs. The system is scalable at low-cost to accommodate multi-antenna multi-static testing for subsurface tomographic imaging.

Abstract: An antenna element includes a dielectric substrate, a radiation electrode, a first ground electrode, a second ground electrode, and a via conductor that connects the first ground electrode and the second ground electrode to each other. The dielectric substrate includes a flat-plate-shaped first part and a second part that is thinner than the first part. The radiation electrode and the first ground electrode are arranged on or in the first part so as to face each other in the thickness direction of the first part. The second ground electrode is spaced apart from the radiation electrode. The second ground electrode is arranged on or in the second part so as to not face the radiation electrode in the thickness direction of the second part. The radiation electrode is capacitively coupled to the second ground electrode and the via conductor.

Abstract: The present disclosure relates to an apparatus and method for synthetically making an ultra-wide imaging bandwidth in millimeter-wave frequencies, resulting in improved image resolutions to values previously unattained. The synthetic approach sums up a number of available sub-bands (channels) to build an unavailable ultra-wideband system. Each channel contains an antenna unit which is optimized for operation within that specific sub-band. The number and position of the channels can be adjusted to cover any frequency range as required for the specific application.
