Abstract

Techniques and mechanisms for providing a low-profile terminal for satellite communication. In an embodiment, a communication terminal includes a radome, an array of radio frequency (RF) elements and a foam layer disposed therebetween. The foam layer includes a first side and a second side opposite the first side, wherein the array of RF elements and the radome are coupled to the foam layer via the first side and the second side, respectively. The communication device provides contiguous structure between the radome and the array of RF elements. In another embodiment, the first side forms a machined surface which contributes to flatness of one or more antenna panels having the array of RF elements disposed therein or thereon.

First claim

What is claimed is:

1. An apparatus comprising:
a radome;
a first foam layer including a first side and a second side opposite the first side, wherein the first foam layer is adhered to the radome via the second side;
an electronically steerable antenna panel coupled to the first foam layer via the first side, the electronically steerable antenna panel configured to participate in a communication of signals which are to propagate through the radome and through the first foam layer;
a base structure to support the antenna panel, wherein the antenna panel is disposed between the base structure and the radome;
a radio-frequency (RF) feed structure; and
a plurality of posts around a periphery of the antenna panel and coupled to the radome, the plurality of posts to operate as standoffs that extend from the radome and abut a surface of the base structure to maintain a parallel spacing of the antenna panel above the RF feed structure.

2. The apparatus of claim 1 , wherein the first side forms a first machined surface of the first foam layer.

3. The apparatus of claim 1 , further comprising:
a second foam layer disposed between the antenna panel and the first foam layer, wherein a side of the second foam layer forms a second machined surface.

4. The apparatus of claim 1 , wherein the first foam layer is adhered to the radome with a pressure sensitive adhesive material.

5. A method comprising:
forming a first foam layer which is disposed on a radome, the first foam layer including a first side and a second side opposite the first side; and
while the first foam layer is adhered to the radome, coupling an electronically steerable antenna panel to the first foam layer via the first side, wherein coupling the electronically steerable antenna panel includes positioning the radome and the first foam layer onto a base structure while the antenna panel is disposed on the base structure, the positioning including abutting a surface of a plurality of posts around a periphery of the antenna panel with the base structure, wherein the posts of the plurality of posts are coupled to and extend from the radome and are operable to maintain a parallel spacing of the antenna panel above an RF feed structure and to facilitate alignment and positioning of the radome with respect to the base structure.

6. The method of claim 5 , wherein forming the first foam layer includes:
depositing a foam material on the radome; and
after the depositing, machining the foam material to form a first machined surface at the first side of the first foam layer.

7. The method of claim 5 , further comprising:
forming a second foam layer coupled to the radome via the first foam layer, wherein a side of the second foam layer forms a second machined surface, and wherein the coupling the electronically steerable antenna panel includes coupling the electronically steerable antenna panel to the first foam layer via the second machined surface.

8. The method of claim 5 , further comprising adhering the second side of the first foam layer to the radome with a pressure sensitive adhesive material.

9. A system comprising
a communication device including:
a radome;
a first foam layer including a first side and a second side opposite the first side, wherein the first foam layer is adhered to the radome via the second side; and
an electronically steerable antenna panel coupled to the first foam layer via the first side, the electronically steerable antenna panel configured to participate in a communication of signals which are to propagate through the radome and through the first foam layer, the antenna panel having an iris metal plane and a patch metal plane;
a base structure to support the antenna panel, wherein the antenna panel is disposed between the base structure and the radome;
a radio-frequency (RF) feed structure;
a plurality of posts around a periphery of the antenna panel and coupled to the radome, the plurality of posts to operate as standoffs that extend from the radome and abut a surface of the base structure to maintain a parallel spacing of the antenna panel above the RF feed structure; and
a display device coupled to the communication device, the display device to display an image based on the communication of signals.

10. The apparatus of claim 9 , wherein the first side forms a first machined surface of the first foam layer.

11. The system of claim 9 , the communication device further comprising:
a second foam layer disposed between the antenna panel and the first foam layer, wherein a side of the second foam layer forms a second machined surface.

12. The system of claim 9 , wherein the first foam layer is adhered to the radome with a pressure sensitive adhesive material.
