Abstract
Abstract An antenna with a first and second portions (16 and 18) that are rotatably movable with respect to each other. The antenna may be rotated from a first position to a second position and from the second position to the first position so that it operates as two antennas while in the first position and as a loop antenna while in the second position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
An antenna system comprising: a first antenna portion; a second antenna portion rotatably coupled to the first antenna portion, the antenna system being movable from an open position to a closed position, in which the first antenna portion is coupled to the second antenna portion to operate as a loop antenna, and movable from the closed position to the open position; a first patch antenna element coupled to the first antenna portion; and a second patch antenna element coupled to the second antenna portion, so that the antenna system is coupled to operate as two patch antennas when the antenna system is in the open position.
Claim 2
Dependent Claim
106 words
An antenna system comprising: a first antenna portion; a second antenna portion rotatably coupled to the first antenna portion, the antenna system being movable from an open position to a closed position, in which the first antenna portion is coupled to the second antenna portion to operate as a loop antenna, and movable from the closed position to the open position; a first patch antenna element coupled to the first antenna portion; and a second patch antenna element coupled to the second antenna portion, so that the antenna system is coupled to operate as two patch antennas when the antenna system is in the open position.
Claim 3
Dependent Claim
21 words
The antenna of claim 1, wherein the first patch antenna element and the second patch antenna element have different resonant frequencies.
Claim 4
Dependent Claim
27 words
The antenna of claim 2, wherein the first patch antenna portion operates in a transmission mode and the second patch antenna portion operates in a reception mode.
Claim 5
Dependent Claim
24 words
The antenna of claim 1, wherein the antenna system operates as two unidirectional patch antennas when the antenna system is in the open position.
Claim 6
Dependent Claim
89 words
An antenna system comprising: a first antenna portion; a second antenna portion rotatably coupled to the first antenna portion so that the second antenna portion may be moved from an open position to a second closed position and from the closed position to the open position; a patch antenna element coupled to the first antenna portion, so that the antenna system operates as a patch antenna when the antenna system is in the open position, and as a loop antenna when the antenna system is in the closed position.
Claim 7
Dependent Claim
89 words
An antenna system comprising: a first antenna portion; a second antenna portion rotatably coupled to the first antenna portion so that the second antenna portion may be moved from an open position to a second closed position and from the closed position to the open position; a patch antenna element coupled to the first antenna portion, so that the antenna system operates as a patch antenna when the antenna system is in the open position, and as a loop antenna when the antenna system is in the closed position.
Claim 8
Dependent Claim
23 words
The antenna system of claim 5, wherein the antenna system operates as a unidirectional patch antenna when it is in the open position.
