Hybrid single aperture inclined antenna
View Patent ↗In an exemplary embodiment, an antenna architecture comprises a single aperture having both receive elements and transmit elements, where the single aperture has the performance of a dual-aperture but in about half the size. Moreover, in the case of an array with inclined elements, there is the need to interconnect a planar substrate with an inclined substrate at an angle. An exemplary single aperture comprises a metal core having a thick pass-through slot from a first side to a second side; connecting the inclined substrate to the first side of the metal core, and connecting a second substrate to the second side of the metal core. Furthermore, an RF signal is communicated between the first substrate and the second substrate in a contactless manner through the thick pass-through slot.
