Abstract:
1. An antenna assembly comprising: a plurality of first substrates each comprising a unitary dipole antenna element, wherein each unitary dipole antenna element comprises a first pair of dipole branches, a first coplanar feed line pair and a first conductor connection substrate tab; a second substrate comprising a plurality of coplanar dipole antenna elements, wherein each coplanar dipole antenna element comprises a second pair of dipole branches, a second coplanar feed line pair and a second conductor connection substrate tab; and a third substrate comprising a plurality of conductor connection cutouts, a first layer and a second layer, wherein the first layer comprises a conductive plane with a plurality of conductor connection clearances, and wherein the second layer comprises a first transmission line feed network and a second transmission line feed network; wherein the second substrate is orthogonal to each of the plurality of first substrates and wherein the third substrate is orthogonal to the second substrate and each of the plurality of first substrates; wherein the first transmission line feed network conductively connects to each respective unitary dipole antenna element via its respective first coplanar feed line pair at a respective one of a plurality of first conductive junctions, each said first conductive junction comprising the respective first conductor connection substrate tab, a first corresponding one of the plurality of conductor connection cutouts, and a first corresponding one of the plurality of conductor connection clearances; and wherein the second transmission line feed network conductively connects to each respective coplanar dipole antenna element via its respective second coplanar feed line pair at a respective one of a plurality of second conductive junctions, each said second conductive junction comprising the respective second conductor connection substrate tab, a second corresponding one of the plurality of conductor connection cutouts, and a second corresponding one of the plurality of conductor connection clearances, wherein each of the plurality of conductor connection clearances is asymmetrically offset relative to a respective one of the plurality of conductor connection cutouts.
