摘要： An antenna assembly includes a phased array antenna having an array of spaced apart antenna elements arranged on a horizontal surface and having an axis of symmetry, and a lens disposed on the phased array antenna. The lens substantially covers the antenna elements. The lens includes a substantially planar bottom surface. The bottom surface and tops of the antenna elements define a gap therebetween. For a second vertical plane orthogonal to the horizontal surface and including the axis of symmetry, the antenna assembly steers a beam in a second vertical plane having a 3dB beam width W1 when steered along a first direction making an angle of less than 10 degrees with a normal to the horizontal surface and a 3dB beam width W2 when steered along a second direction making an angle of greater than 40 degrees with the normal, W1 and W2 within 35% of each other.

摘要： In some examples, a sensor comprises a circuit including an inductor. The inductor comprises an inductor layer, a reference layer comprising at least one of an electrically conductive material or a magnetic material, and a variable layer formed between the reference layer and inductor layer. A thickness of the variable layer may be configured to change upon application of a force external to the variable layer thereby causing a change in position of the reference layer relative the inductor layer, and the change in position of the reference layer relative the inductor layer changes an inductance of the inductor. The sensor may be configured to detect the force based on the change in inductance of the inductor.

摘要： An optical stack (100) includes a substrate (110), a radio-wave anti-reflection sheet (130) configured to reduce reflection from the optical stack (100) of radio waves at a predetermined operating frequency (f), and a visible light reflective, infrared light transmissive multilayer optical film (120) disposed between the radio-wave anti-reflection sheet (130) and the substrate (110). For radiation substantially normally incident on the radio-wave anti-reflection sheet (130) and for a first frequency range at least 20 GHz wide, centered on the predetermined operating frequency (f), and disposed between about 1 GHz and about 120 GHz, a return loss of the optical stack (100) is asymmetric about the predetermined operating frequency (f) in the first frequency range. The optical stack (100) has a largest return loss S11L in the first frequency range of less than -10 dB and a difference between the largest return loss S11L and a smallest return loss S11S in the first frequency range is less than about 2 dB.

摘要： A device is described having one or more conductive loops to produce an electromagnetic field, such as for wireless power transfer to an electronic device. In some examples, an antenna is used with at least one resonating capacitor ring that is relatively co-planar with the antenna, and that is magnetically coupled to the antenna but is not electrically powered by an external source. In addition, a device is described having two or more thin-film coils, each coil comprising a pair of terminals and at least one loop defining a plane and an interior region. In some examples, the planes of the two or more coils are disposed substantially parallel to one another, the interior regions of the two or more coils at least partially overlap one another, and the pairs of terminals of the antennae are electrically connected in parallel.
