Examples disclosed herein relate to a radiating structure. The radiating structure has a transmission array structure having a plurality of transmission paths, each transmission path having a plurality of slots. The radiating structure also has a radiating array structure of a plurality of radiating elements, with each radiating element corresponding to at least one slot from the plurality of slots, the radiating array structure positioned proximate the transmission array structure. A feed coupling structure is coupled to the transmission array structure and adapted for propagation of a transmission signal to the transmission array structure, the transmission signal radiated through at least one of the plurality of slots and at least one of the plurality of radiating elements.

This antenna device is provided with: a ground; strip lines that extend from positions facing each other with respect to the width direction of the ground; a plurality of slots which is provided to the ground and which intersects with straight lines along the strip lines; and branch lines which intersect with the slots that are positioned to face the branch lines in a back surface.

A multiband compatible antenna that resonates at a first frequency and a second frequency includes: a planar conductor including a feeding portion to which a signal is supplied, a grounding portion, and a slit between the feeding portion and grounding portion. The slit includes a first slit portion extending in a first direction and a second slit portion extending in a second direction intersecting the first direction from an end of the first slit portion. The first slit portion is disposed closer to one edge than a center of the planar conductor in the second direction, and the feeding portion is disposed to a side of the first slit portion closer to the one edge. The planar conductor includes a first element portion and a second frequency portion that resonate at the first frequency and the second frequency, respectively. The second slit portion is disposed in the first element portion.

Antennas oriented at a first orientation toward an area of interest can transform radar signals through a first transformation that physically maps the plurality of radar signals with a plurality of unique beam angles corresponding to a plurality of unique frequencies. Antennas oriented at a second orientation toward the area of interest can transform radar signals through a second transformation completing the first transformation. A frequency scan can be performed on a first plurality of responses to first radar signals to identify first spatial data along a first dimension. Second spatial data at second spatial location along a second dimension can be created from a second plurality of responses corresponding to the second transformation. An image can be generated using the first spatial data and the second spatial data while a range value of the area of interest can be determined using the first plurality of responses.
