One embodiment of his innovation demonstrated here features a unique antenna structure: a slot resonator with a waveguide filled by a light-transmissive dielectric material. The housing may be comprised of a conductive metal. This design allows for dual use of a slot resonator and a LED light guide which allows for unhampered operation. This invention includes using a cut out in the housing of a device as a slot resonator antenna. The cut out in the housing is also used as an aperture for a light pipe that can be used to show different light indicia.

Slot Antenna Integrated Dielectric Light Pipe

Demanding more functionality in less space drives the equipment and component industry to

miniaturization. Electronic equipment has been scaled from cabinet size down to desktop, portable,

wearable, and eventually implantable, with no apparent physical limit.

However, limits do exist with regard to wireless equipment, where required operating wavelengths and

desired bandwidth performance mandate certain physical size limitations on the design of antennas and

associated equipment. Designers must sometimes trade off wireless range, beam width, supported

channels, or operating wavelength in order to reduce device size. In some cases FCC compliance or

support for international operating frequencies may need to be compromised if device size is to be


Antennae are waveguides, structured to convey energy from one dimension into two dimensions, in order

to propagate signals into a three dimensional space. A waveguide could be solid, hollow, or a slot. A

waveguide slot may be known as a slot waveguide or slot antenna. By creatively designing various

components of the electronic equipment to perform both a physical function and a waveguide function,

the device may be able to support required wireless capabilities with minimal changes in overall

dimensions. These changes could involve adding or removing material to create a slot waveguide in a

housing component, or changing material to provide areas of conductivity or non-conductivi...
