Abstract
Systems and methods for communicating over multiple frequency bands include a driven antenna element and a parasitic element communicatively coupled to the driven antenna element, the parasitic element including at least a first and a second conductive section. The parasitic element can include two or more conductive sections, and the sections can be coupled using a connector (e.g., switching element or trap). Further, some driven antenna elements may be associated with two or more parasitic elements.
Claims33
A system for communicating over multiple frequency bands, said system comprising:
- a driven antenna element;
- a parasitic element communicatively coupled to said driven antenna element, said parasitic element including at least a first and a second conductive section.
A method for building an antenna component, said method comprising:
- providing a driven antenna element, said driven antenna element operable to communicate in at least a first frequency band;
- and
- communicatively coupling a parasitic element to said driven antenna element, wherein said parasitic element includes a first conductive portion and a second conductive portion connected together by a connecting element.
A method for operating a multi-band antenna system, said multi-band antenna system including a driven antenna element and a parasitic element communicatively coupled to said driven antenna element to form an antenna component, said driven antenna element operable to resonate at a first frequency band, and wherein said parasitic element includes at least a first and a second conducting section coupled together with a switching element, said method comprising:
- closing said switching element, thereby connecting said first conducting section to said second conducting section and causing said antenna component to resonate at least at a second frequency band;
- and
- opening said switching element, thereby disconnecting said second conducting section from said first conducting section and causing said antenna component to resonate at least at a third frequency band.
A system for communicating at multiple frequency bands, said system comprising:
- means for communicating signals in a first frequency band;
- means positioned within a near field pattern of said communicating means for shifting said first frequency band and for causing said communicating means to resonate in at least two other frequency bands different from said shifted first frequency band, said means for causing including at least a first and a second conducting section;
- and
- means for conductively connecting said first and said second conducting sections.
