Abstract
A radio frequency (RF) aperture includes an interface printed circuit board. An array of electrically conductive tapered projections have bases disposed on a front side of the interface printed circuit board and extend away from the front side of the interface printed circuit board. Chip baluns are mounted on the back side of the interface printed circuit board. Each chip balun has a balanced port electrically connected with two neighboring electrically conductive tapered projections via electrical feedthroughs passing through the interface printed circuit board. Each chip balun further has an unbalanced port, and RF circuitry disposed at the back side of the interface printed circuit board is electrically connected with the unbalanced ports of the chip baluns. The electrically conductive tapered projections include dielectric tapered projections and an electrically conductive layer disposed on an inner or outer surface of the dielectric tapered projections.
