1. A mechanically reconfigurable antenna comprising:
- a patch antenna;
one or more parasitic patches; and
a radially foldable linkage associated with the patch antenna that can be actuated to move the parasitic patches radially inward and radially outward relative to the patch antenna to change an electromagnetic property of the antenna.

Abstract
In some embodiments, a mechanically reconfigurable antenna includes a patch antenna, one or more parasitic patches, and a radially foldable linkage associated with the patch antenna that can be actuated to move the parasitic patches radially inward and radially outward relative to the patch antenna to change an electromagnetic property of the antenna.

13. A mechanically reconfigurable antenna comprising:
-
a planar Hoberman linkage including an upper ring, a lower ring, an upper linkage element, and a lower linkage element, the upper and lower rings each comprising an inner opening, the upper and lower linkage elements being radially expandable and collapsible; pins mounted to the upper and lower linkage elements that connect the linkage elements together, the pins also extending into the inner openings of the upper and lower rings; a circular microstrip patch antenna associated with the planar Hoberman linkage; and parasitic patches mounted to at least one of the linkage elements in proximity to the patch antenna; wherein rotation of one of the rings relative to the other ring urges the pins to radially inward or outward, which causes radial collapsing or expanding of the linkage elements, which causes inward or outward radial movement of the parasitic patches relative to the patch antenna so as to change an operating frequency of the antenna. - View Dependent Claims (14, 15, 16)

17. A method for adjusting an electromagnetic property of an antenna, the method comprising:
-
associating a radially foldable linkage with a patch antenna, wherein parasitic patches are mounted to the linkage; and actuating the linkage in a manner in which the parasitic patches move radially inward or outward relative to the patch antenna. - View Dependent Claims (18, 19, 20)
