A multi-frequency antenna comprising an IMD element, one or more active tuning elements and one or more parasitic elements. The IMD element is used in combination with the active tuning and parasitic elements for enabling a variable frequency at which the antenna operates, wherein, when excited, the parasitic elements may couple with the IMD element to change an operating characteristic of the IMD element.

Antenna with active elements

A multi-function array is described where several communication system functions are realized using the same antenna architecture. An array of antenna elements where each antenna element can generate multiple radiation patterns is described; the multiple radiation patterns from each antenna element provides increased capability and flexibility in generating a phased array, a MIMO antenna system, a receive diversity antenna system, as well as direction finding feature by way of an interferometer function provided by one or multiple elements. The small volume attributes of the antenna elements populating the array lend this technique to mobile wireless devices as well as access points.

Multi-function array for access point and mobile wireless systems

The present disclosure includes a system and method for conducting radio frequency signals using multiple layers. In some implementations, a signal transfer element configured to passively transfer RF signals between a first region and a second region includes a first conductor layer having a first continuous conductor configured as a first portion of a first antenna, a transmission line, and a first portion of a second antenna. The first antenna and the second antenna are configured to wirelessly receive and transmit Radio Frequency (RF) signals. The signal transfer element also includes a second conductor layer having a second continuous conductor configured as a second portion of the first antenna, a ground plane, and a second portion of the second antenna. The first conductor layer and the second conductor layer are spatially proximate such that the transmission line and the ground plane are configured to passively transfer RF signals between the first antenna and the second antenna independent of an electrical connection between the first conductor layer and the second conductor layer.

A multi-frequency antenna comprising an IMD element, active tuning elements and parasitic elements.

Various resonant modes of a multiresonant antenna structure share at least portions of the structure volume. The basic antenna element has a substantially planar structure with a planar conductor and a pair of parallel elongated conductors, each having a first end electrically connected to the planar conductor. Additional elements may be coupled to the basic element in an array. In this way, individual antenna structures share common elements and volumes, thereby increasing the ratio of relative bandwidth to volume.
