An RF lens includes a multitude of radiators adapted to transmit radio frequency electromagnetic EM waves whose phases are modulated so as to concentrate the radiated power in a small volume of space in order to power an electronic device positioned in that space. Accordingly, the waves emitted by the radiators are caused to interfere constructively at that space. The multitude of radiators are optionally formed in a one-dimensional or two-dimensional array. The electromagnetic waves radiated by the radiators have the same frequency but variable amplitudes.

The present disclosure relates to antenna devices and arrays of antenna devices. One example antenna device includes a first radiator configured to radiate a first electromagnetic signal, a second radiator configured to radiate a second electromagnetic signal, and a joint feeding network including a first 180-degree coupler and a second 180-degree coupler arranged in sequence. The first 180-degree coupler receives first input signal and second input signal, and the second 180-degree coupler provides first output signal to the first radiator and second output signal to the second radiator. In the joint feeding network, a first path connects the first 180-degree coupler to the second 180-degree coupler including a first phase shifter. A second path connects the first 180-degree coupler to the second 180-degree coupler including a second phase shifter and an attenuator.

A transceiver for low-complexity beam steering. The transceiver has a first antenna array including a first sub-aperture with a first native beam steering angle and a second antenna array including a second sub-aperture with a second native beam steering angle different than the first native beam steering angle. The first antenna array and the second antenna array are arranged in the transceiver such that the first sub-aperture is combinable with the second sub-aperture to form a combined aperture when the first antenna array and the second antenna array are excited.

Structures and formation methods of a chip package are provided. The chip package includes a semiconductor die having a conductive element and an antenna element over the semiconductor die. The chip package also includes a first conductive feature electrically connecting the conductive element of the semiconductor die and the antenna element. The chip package further includes a protective layer surrounding the first conductive feature. In addition, the chip package includes a second conductive feature over the first conductive feature. A portion of the second conductive feature is between the first conductive feature and the protective layer.

An antenna module includes digital phase shifters, a plurality of antenna elements arranged in a first direction, and a fixed phase shifter. Each of the digital phase shifters changes a phase of a signal to a first phase value. The fixed phase shifter changes a phase of a signal to a second phase value, the second phase value being obtained by adding a predetermined offset phase value to the first phase value. A middle point of a virtual line is an antenna center and connects a center of an antenna element located on an end in the first direction and a center of an antenna element located on a different end. Under a symmetrical condition, an antenna center among the plurality of antenna elements are paired as an antenna element pair, the fixed phase shifter is electrically connected to at least one antenna element of the antenna element pair.
