  • Publication number: 20240145922
    Abstract: An antenna system includes a plurality of PIFA/IFA type wherein each of the plurality of antennas have either a same short pin or different short pins located together to minimize antenna separation between the plurality of antennas. The antennas share the same short pin with the width between at least two antennas of the plurality of antennas designed to minimize coupling when the at least two antennas operate at a same frequency. The short pin width is at least ?/8 where ? is based on a lowest frequency of operation of the antenna system, the lowest frequency of operation is about 2.4 GHz. The common short pin also includes a minimum distance to the associated antenna feed. Where the different short pins are located together the antenna includes a first short pin as a cylinder and a second short pin located within the cylinder without contact therebetween.

    Abstract: A wireless device with a slot antenna includes one or more heat spreaders, a PCB with vias to allow current to flow through the PCB, various components disposed on the PCB, and a slot antenna compliment. By layering the components, e.g., heat spreaders, PCB, slot antenna compliment, etc. one or more slot antennas are formed from these components as to integrate the slot antennas into the existing structure. The formed slot antenna is a spiraled shape as to reduce the overall footprint of the slot antenna while keeping the required quarter-wavelength total effective length of an open-slot antenna. The formed slot antenna is wide enough to allow the antenna to accommodate a wide bandwidth and may include a plurality of steps to further allow for tuning of the length of the slot antenna. The wireless device can further include a housing enclosing the internal components.
