Abstract
An antenna in a lightbulb may include a conductive plane (e.g., a ground plane) that includes an edge-enabled void antenna (EEVA) with the EEVA including a corresponding edge-enabled void isolator (EEVI). Use of both the EEVA and the EEVI allows for a small antenna footprint for incorporation into a lightbulb. Optionally, two EEVAs, each with a corresponding EEVI may be used. Various arrangements are provided to illustrate possible compromises between structural integrity and cooling. Further, by using two EEVAs, diversity reception and transmission is possible, increasing the utility of the lightbulb by expanding directionality of the transmission/reception and/or improving communication through spatial diversity.
Claims19
An antenna system comprising:
- a conductive plane having a geometric perimeter, the conductive plane delimiting an edge-enabled void antenna (EEVA), wherein the EEVA extends from the geometric perimeter of the conductive plane toward a geometric center of the conductive plane;
- a substrate positioned underneath the conductive plane;
- and
- a cooling disc positioned underneath the substrate, the cooling disc being generally planar in a plane and substantially continuous across a portion of the plane within a second geometric perimeter, and delimiting at least a first portion of an edge-enabled void isolator (EEVI) extending from the second geometric perimeter toward a second geometric center of the cooling disc, the EEVI associated with the EEVA.
A lightbulb comprising:
- a bottom post;
- a cooling cone positioned on top of the bottom post and extending upwardly therefrom;
- a cooling disc formed from a substantially continuous material within a disc perimeter, the cooling disc capping the cooling cone and defining a first plane;
- a substrate positioned on the cooling disc and defining a second plane parallel to the first plane;
- a conductive plane positioned on top of the substrate and defining a third plane parallel to the first plane, the conductive plane delimiting an edge-enabled void antenna (EEVA), wherein the EEVA extends from a geometric perimeter of the conductive plane toward a geometric center of the conductive plane.
