    摘要: Multi-frequency, low-profile, capacitively loaded magnetic dipole antennas to be used in wireless communications. Each antenna comprises one to n antenna elements and each element having one to n arms. The various antenna embodiments can cover a range of frequencies to be determined by the shape, size, and number of elements in the physical configuration of the antenna. The antenna configuration can also be adapted to expand frequency bands covered by the antenna or to fit within space restrictions dictated by specific antenna applications.

    摘要: The disclosed embodiments of antenna elements and antenna element arrangements provide a generally low profile, improved isolation, and providing a larger bandwidth. Certain disclosed antenna elements provide a reduction in the footprint of the antenna elements while maintaining the performance characteristics by providing a greater surface area on either a top, middle or bottom portion of a CLMD antenna. Other disclosed antenna element arrangements provide improved radiation efficiency by providing metallic reflectors on the sides of antenna elements. The isolation characteristics of certain disclosed antenna elements are improved through the use of coplanar wave guides. The bandwidth may be improved through the use of stubs resonators. The bandwidth of the antenna elements may be improved without reducing isolation or shielding by providing a variable gap between two portions of the antenna elements.

    摘要: A capacitively loaded magnetic dipole is configured with an E-field distribution so that the thickness of the antenna can be reduced while still maintaining high efficiency. The basic antenna element comprises a ground plane; a first conductor extending longitudinally above the ground plane having a first end electrically connected to the ground plane; a second conductor extending longitudinally above the ground plane and parallel to the first conductor, the second conductor also having a first electrically connected to the ground plane; and an antenna feed coupled to the first conductor. Both of the conductors are spaced equidistantly above the ground plane.

    摘要: The disclosed embodiments of the present invention include an antenna element having a generally low profile and providing a larger bandwidth. The disclosed embodiments include antenna elements having a top section with at least one cutout. Each cutout is provided with one or more tongues therein. The tongues extend from an edge of the cutout inward. The tongues may be coplanar with the top section or may be positioned between the top section and a bottom plate. Each tongue may be positioned separately to produce the desired antenna element characteristics.
