Abstract

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.

Claims

1. A single antenna aperture of an antenna system, the single antenna aperture comprising:

multiple receiving elements and multiple transmitting elements;

wherein the multiple receiving elements are interleaved with the multiple transmitting elements.

2. The single antenna aperture of claim 1, wherein the multiple receiving elements are oriented in a first direction, wherein the multiple transmitting elements are oriented in a second direction, and wherein the first direction is opposite of the second direction.

3. The single antenna aperture of claim 2, wherein the multiple receiving elements are “

T”

-shaped and wherein the multiple transmitting elements are “

T”

-shaped.

4. The single antenna aperture of claim 1, wherein a first receiving element of the multiple receiving elements is located within about 0.5 wavelengths or less of a first transmitting element of the multiple transmitting elements, wherein the 0.5 wavelengths is based on the highest radiated frequency for the multiple receiving elements.

5. The single antenna aperture of claim 1, wherein a first receiving element of the multiple receiving elements is located within about 1.0 wavelength or less of a second receiving element of the multiple receiving elements, wherein the 1.0 wavelength is based on the highest radiated frequency for the multiple receiving elements.

6. The single antenna aperture of claim 1, wherein each of the multiple receiving elements comprise an individual receive chain, and wherein each of the multiple transmitting elements comprise an individual transmit chain.
