An antenna element and related apparatus are provided. The antenna element includes a radiating structure configured to radiate a radio frequency (RF) signal in a defined polarization (e.g., linear polarization or circular polarization). The radiating structure is conductively coupled to a first pair of feed ports and a second pair of feed ports. In examples discussed herein, at least one selected pair of feed ports among the first pair of feed ports and the second pair of feed ports can be dynamically configured to receive a differential signal(s). By applying the differential signal(s) to the selected pair of feed ports with a proper polarity and/or a relative phase differential, it may be possible to cause the radiating structure to radiate in the defined polarization without requiring additional circuitries (e.g., switching circuit), thus helping to reduce power consumption, heat dissipation, and/or footprint in an apparatus employing the antenna element.

Antenna element and related apparatus

A radio frequency (RF) front-end apparatus is provided. In examples discussed herein, the RF front-end apparatus can be configured to communicate RF signals in millimeter wave (mmWave) RF frequencies (e.g., &#x2265;12 GHz). The RF front-end apparatus includes an RF front-end circuit and an antenna element. The RF front-end circuit includes a transmit path and a receive path for transmitting and receiving RF signals, respectively. The antenna element includes an input port(s) and an output port(s) that are coupled to the transmit path and the receive path, respectively. The antenna element can be configured to enable impedance matching between the input port(s) and the transmit path, as well as between the output port(s) and the receive path. As a result, it may be possible to reduce insertion losses in the RF front-end circuit, thus helping to improve performance of the RF front-end apparatus, particularly in support of mmWave communications.

Radio frequency front-end apparatus

Embodiments of circuits, devices, and methods related to a radio frequency switch are disclosed. In various embodiments, a circuit may comprise a series path including a series transistor to be switched on during a first mode of operation; a shunt path including a shunt transistor to be switched off during the first mode of operation; and a return path including a return transistor to be switched on during the first mode of operation. Other embodiments may also be described and claimed.
