Abstract
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.
