Abstract
Disclosed are impedance loaded ground plane configurations suitable for use with a wide variety of antennas. The impedance loaded ground plane allows the antenna-ground plane combination to achieve a small form factor without sacrificing the performance or efficiency of the antenna.
Claims26
An antenna system comprising:
- an antenna configurable to operate in a range of 600 MHz to 1000 MHz at an efficiency greater than 70%;
- and
- a ground plane electrically connected to the antenna at an attachment location of the antenna, the ground plane having a length from the attachment location to a farthest edge of the ground plane of less than 100 mm.
A ground plane for use with an antenna comprising:
- a ground plane having a longest exterior dimension of less than 120 mm;
- a first slot extending into the ground plane from a first location on the perimeter of the ground plane;
- and
- a second slot extending into the ground plane from a second location on the perimeter of the ground plane, at least a portion of the first slot extending adjacent at least a portion of the second slot.
1 more element
A method of optimizing a ground plane for use with an antenna comprising:
- selecting a shape of the ground plane;
- identifying an antenna position on the ground plane wherein the antenna position is near an edge of the ground plane;
- and
- positioning one or more slots on the ground plane between the antenna position and the location on the ground plane farthest from the antenna position.
