DETAILED DESCRIPTION

Conventionally, ground terminals that use a parabolic dish typically include a separate feed to accommodate various dish sizes. The feed (or feed horn) of the parabolic dish may be the focal point where the RF energy is concentrated on. This focal point varies based on the size and curvature of the dish.

An antenna or dish may refer to a component of a ground terminal that includes a feed. Those skilled in the art recognize, that the described functionality may be applied to a dish feed or, more broadly, an antenna feed.

FIG. 1 illustrates an exemplary antenna positioning system 100, according to example embodiments. As shown, antenna positioning system 100 may include at least a reflector 102 and a feed 104. Reflector 102 may be configured to receive or reflect electromagnetic waves. Generally, reflector 102 may be formed of a parabolic shaped body. Reflector 102 may be positioned around feed 104. Feed 104 may be positioned at a focal point of reflector 102. Feed 104 may be configured to receive electromagnetic waves transmitted to antenna positioning system 100 and/or transmit electromagnetic waves from antenna positioning system 100.

In some circumstances, an operator of antenna positioning system 100 may wish to change the size of reflector 102. For example, an operator may wish to maintain several sizes of reflectors 102 (e.g., 60 cm, 80 cm, 100 cm, 130 cm, etc.) and change the size or reflector 102 accordingly. Conventionally, in order to operate an antenna positioning system 100 properly with varying dimensions and or bands, an operator would need to purchase a new feed 104. This is because, in order for antenna positioning system 100 to operate properly, feed 104 may be positioned at the focal point of reflector 102. As such, once the size of reflector 102 changes, so does the focal point of reflector 102. Accordingly, in conventional systems, a different sized feed 104 is needed for each size of reflector 102.

The one or more embodiments described herein provides an improvement over conventional antenna positioning systems 100 by providing a mechanically adjustable feed that can be dynamically modified to account for changes in reflector size.

FIGS. 2A and 2B illustrate an adjustable feed 200, according to example embodiments. As shown, adjustable feed 200 may include a feed base 202 and a splash plate assembly 204. Feed base 202 may correspond to a component of adjustable feed 200 that may remain constant, regardless of the size of reflector (e.g., reflector 102) used in an antenna positioning system. In some embodiments, feed base 202 may be mounted in the center of the reflector.

In some embodiments, splash plate assembly 204 may be removably coupled with feed base 202. For example, feed base 202 may be removably coupled with splash plate assembly 204 via one or more coupling mechanisms 206 and 208. Splash plate assembly 204 may be configured to act as a feed horn for adjustable feed 200. Generally, each type of splash plate assembly 204 may be frequency dependent. For example, the size and shape of splash plate assembly 204 may define the operating frequency of an antenna positioning system. Because splash plate assembly 204 may be removed from feed base 202, adjustable feed 200 allows for different splash plate assemblies to be used based on a desired frequency for an antenna positioning system. Using a specific example, in an exemplary embodiment, an operator may utilize a first type of splash plate assembly 204 for an X band feed a second type of assembly for a Ka band feed, and a third type of assembly for a Ku band. In this manner, an operator can adjust the operating frequency of an antenna positioning system without replacing the entire feed assembly.

FIGS. 3A and 3B illustrate adjustable feed 200, according to example embodiments. In some embodiments, an operator of an antenna positioning system may wish to change a size of its reflector. For example, an operator of an antenna positioning system may wish to utilize a larger reflector. In this manner, the operator may need a longer feed in order to be correctly positioned at the new focal point. To account for this, adjustable feed 200 may further include a feed insert 302 having a first end 304a and a second end 304b.

In some embodiments, feed base 202 may be removably coupled with feed insert 302 at a first end 304a of feed insert 302. For example, feed base 202 may be removably coupled with feed insert 302 at first end 304a via coupling mechanisms 206 and 306. Feed insert 302 may be selectively added to adjustable feed 200 to change a length of adjustable feed 200. Continuing with the above example, feed insert 302 may be added to adjustable feed 200 to account for a new focal point.

To complete adjustable feed 200, feed insert 302 may be removably coupled with splash plate assembly 204 at second end 304b. For example, feed insert 302 may be removably coupled with splash plate assembly via coupling mechanisms 308 and 208.

Although FIGS. 3A and 3B are shown and discussed with respect to adding a single feed insert 302, those skilled in the art understand that multiple feed inserts 302 may be added to further extend a total length of adjustable feed 200. For example, multiple feed inserts 302 may positioned between feed base 202 and splash plate assembly 204 to account for varying focal points. Further, because adjustable feed 200 also allows for the interchanging of splash plate assemblies 204, depending on a desired operating frequency, adjustable feed 200 provides a dynamic feed for an antenna positioning system that can allow for both various sizes of reflectors (e.g., by adding or subtracting feed inserts 302) and various operating frequencies (e.g., by swapping out splash plate assemblies 204).

For example, FIGS. 5A and 5B illustrate second adjustable feed 200 with a further feed insert 502 positioned between feed base 202 and splash plate assembly 204, according to example embodiments. Further feed insert 502 may be configured similar to feed insert 302. For example, further feed insert 502 may include a first end 504a and a second end 504b. First end 504a of further feed insert 502 may interface with second end 304b of feed insert 302 via coupling mechanisms 308 and 508. Second end 504b of further feed insert 502 may interface with splash plate assembly 204 via coupling mechanisms 208 and 508.

FIG. 4 illustrates various antenna positioning system 402, according to example embodiments. As shown, various antenna positioning systems 402 may include one or more reflectors 404 and one or more adjustable feeds 406. Each reflector 404 may correspond to a differently sized adjustable feed 406, depending on a focal point of each respective reflector 404. Similarly, each adjustable feed 406 may one or more feed inserts based on the focal point of each respective reflector 404. Further, each adjustable feed 406 may include a different splash plate assembly based on a desired operating frequency.
