Abstract: An antenna may include a first printed circuit board (PCB), a second PCB, a dielectric disposed between the first and the second PCB, and electrical connection configured to connection a subset of conducting elements from the first PCB to the second PCB. The first PCB includes a first and a second conducting elements and a ground conducting element. The second PCB includes a third conducting element. The electrical connection connects the first conducting element to the third conducting element. A first portion of the ground conducting element provides a ground reference for the first conducting element and the third conducting element. A second portion of the ground conducting element provides a ground reference for the second conducting element. The first and third conducting elements resonate over a first range of frequencies. The second conducting element is configured to resonate over a second range of frequencies.

Abstract: A printed circuit board (PCB) includes a front side and a back side. A first conducting element disposed on the front side resonates over a first range of frequencies. A second conducting element disposed on the back side resonates over a second range of frequencies. A ground conducting element disposed on the front side where a first portion of the ground conducting element provides a ground reference for the first conducting element. A second portion of the ground conducting element provides a ground reference for the second conducting element. Resonance over the first range of frequencies is associated with a length of the first portion of the ground conducting element and a length of the first conducing element. Resonance over the second range of frequencies is associated with a length of the second portion of the ground conducting element and a length of the second conducting element.

Abstract: A high gain, phased array antenna includes a conducting sheet having a number of one or more slots defined therein. For each slot, an electrical microstrip feed line is electronically coupled with a corresponding slot to form a magnetically-coupled LC resonance element. A main feed line couples with the one or more microstrip feed lines. At least one slot and/or microstrip feed line includes at least one segment with greater width than other segments.

Abstract: In one embodiment, a meander slot antenna includes a conducting sheet having a meander slot defined therein. The meander slot has a closed area defined by the conducting sheet. An electrical microstrip feed line crosses the meander slot. The electrical microstrip feed line and meander slot provide a magnetically coupled LC resonance element. A dielectric material has at least one conductive via therein. The at least one conductive via electrically connects the electrical microstrip feed line and the conducting sheet at a side of the meander slot. The dielectric material otherwise separates the conducting sheet from the electrical microstrip feed line. Other embodiments are also disclosed.

Abstract: A high gain, steerable phased array antenna includes multiple oblong slots. For each of the oblong and preferably rectangular slots, an electrical microstrip feed line is disposed within a parallel plane to the slot, and extends in the short dimension of the slot across the center of its long dimension. The microstrip feed lines and corresponding oblong slots form magnetically coupled LC resonance elements. A main feed line couples with the microstrip feed lines. Delay circuitry is used to electronically steer the antenna by selectively changing signal phases on the microstrip feed lines. One or more processors operating based on program code continuously or periodically determine a preferred signal direction and control the delay circuitry to steer the antenna in the preferred direction. The preferred signal direction is determined based on a directional throughput determination.
