ABSTRACT:
Low-profile, compact embedded antenna designs are provided for use with computing devices, such as laptop computers, which enable ease of integration within computing devices with limited space, while providing suitable antenna characteristics (e.g., impedance matching and radiation efficiency) over a desired bandwidth of operation. Compact antenna designs with reduced antenna size (e.g., antenna height) and increased operational bandwidth (e.g., broadband impedance matching) are achieved using slotted ground plane designs and/or doubling antenna feeding schemes.
