Multi mode antenna system
First Claim
1. An antenna system comprising:
- a first antenna element;
a second antenna element, said first and second elements defining at least in part a slot element;
an active switching network in communication with one or both of said first and second antenna elements, said switching network operable to cause said antenna system to resonate in each of two modes;
a first mode of said modes wherein said first element resonates at a first set of frequencies, and said first element and a second element resonate together at a second set of frequencies; and
a second mode of said modes wherein said first element resonates substantially at said first set of frequencies, and said slot element resonates at a third set of frequencies.

Abstract
An antenna system comprising a first antenna element, a second antenna element, the first and second elements defining at least in part a slot element, an active switching network in communication with one or both of the first and second antenna elements, the switching network operable to cause the antenna system to resonate in each of two modes: a first mode wherein the first element resonates at a first set of frequencies, and the first element and a second element resonate together at a second set of frequencies; and a second mode wherein the first element resonates at the first set of frequencies, and the slot element resonates at a third set of frequencies.

11. A method for operating an antenna system, said method comprising:
-
resonating a first antenna element at a first set of frequencies while resonating said first antenna element and a second antenna element in said antenna system at a second set of frequencies; adjusting an active switching network that is in communication with one or more of said first and second antenna elements, thereby resonating said first antenna element substantially at said first set of frequencies and a slot element at a third set of frequencies, said slot element defined by the placement of said first and second antenna elements. - View Dependent Claims (12, 13, 14, 15, 16)

17. An antenna system comprising:
-
a first antenna element; a second antenna element; a slot element defined, at least in part, by said first and second antenna elements; and means in communication with one or both of said first and second antenna elements for causing said antenna system to operate in each of two modes; a first mode of said modes wherein said first element resonates at a first set of frequencies, and said first element and a second element resonate together at a second set of frequencies; and a second mode of said modes wherein said first element resonates substantially at said first set of frequencies, and said slot element resonates at a third set of frequencies. - View Dependent Claims (18, 19, 20, 21, 22)
