Abstract
Tightly coupled array antennas exhibit wideband behavior when all elements are excited simultaneously. A switched splitter-combiner allows a scalable number of adjacent feed elements of the array to be excited depending on the frequency of excitation and degree of coupling. This allows the tightly coupled array to be locally excited while retaining wideband performance. The performance may be further improved by complex per-element control of excited elements or tunable reactive termination of non-excited elements.
Claims14
An apparatus comprising:
- an array of tightly coupled feed elements;
- a switched splitter-combiner circuit coupled to a radio frequency (RF) port;
- and
- a controller, configured to operate the switched splitter-combiner circuit such that RF power incident at the RF port is dynamically routed to all or a subset of the feed elements.
1 more element
An apparatus comprising:
- an array of tightly coupled feed elements;
- a coupler circuit for selectively coupling one or more tuned impedances between a radio frequency (RF) port and one or more of the feed elements;
- and
- a controller, configured to operate the coupler circuit such that RF power incident at the RF port is dynamically routed to all or a subset of the feed elements.
