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.

Abstract: An edge enabled void isolator (EEVI) for antennas is provided. In particular, two or more antennas are separated from one another by respective EEVI to provide isolation between the antennas. This isolation allows the antennas to be placed in close proximity, keeping the footprint of the antenna system relatively small for ease of use in small wireless devices. While two monopole antennas are specifically contemplated, the disclosure may be extended to more than two antennas and these antennas may be monopole, dipole, F, or the like.

Abstract: A wireless communication system comprising one or more cross polarized antenna assemblies with optimized propagation delay that form part of an antenna module having two dominant perpendicular polarizations.

Abstract: In some embodiments, a printed circuit board is disclosed. The printed circuit board includes a substrate, a conductive plane, and at least one switch. The conductive plane includes an edge enabled void construction (EEVC) along a geometric perimeter of the conductive plane, the EEVC having an EEVC void that defines an EEVC perimeter that extends into the conductive plane.

Abstract: An edge enabled void antenna (EEVA) apparatus is provided. The EEVA apparatus includes a conductive plane and a void is created on a geometric perimeter of the conductive plane to form an EEVA. A radio frequency (RF) port is coupled to the void to receive an RF signal. The RF signal excites the conductive plane to induce an electrical current along the geometric perimeter of the conductive plane. The void can cause the electrical current to increase and decrease on the geometric perimeter of the conductive plane, thus causing an electromagnetic wave corresponding to the RF signal being radiated from the EEVA. By forming the EEVA on the geometric perimeter of the conductive plane, it may be possible to enable a well-functioning antenna apparatus with a small effective footprint, thus allowing multiple EEVAs to be provided in a space confined wireless device with sufficient isolation for improved RF performance.
