Abstract
An antenna device includes a substrate, and a radiating element disposed on the substrate. The radiating element has two spiral arms unfurling in an Archimedean progression and terminating in a logarithmic progression. The substrate is formed from a dielectric material and includes multiple perforations for providing passage of coolant through the substrate. The radiating element is disposed on a front surface of the substrate, and an enclosure is formed on a rear surface of the substrate to provide a reflective cavity for reflecting radiation to the front surface of the substrate. The enclosure includes a hexagonal perimeter formed by a wall. The antenna device may be used as an element in a planar phased array.
