A multiport planar antenna system with digital reconfigurability to adjust a beam-steering function of the system is described herein. A substrate is provided and a grid of parasitic elements is printed on a surface of the substrate. One or more driven, radiating elements such as monopole or dipole antennas are printed on the substrate proximate the parasitic elements. Switching elements between adjacent parasitic elements are then configured to steer the radiation direction in a particular direction in the azimuth plane. The small form factor of the planar antenna system can be used in a multiple-input, multiple-output (MIMO) application used by fifth generation (5G) devices such as mobile phones, internet of things (IoT) devices, and vehicles.

An antenna for multi-broadband and multi-polarization communication, may include a plurality of radiators configured to jointly function as one or more dipoles, a first feed terminal for a first signal of a first polarization, and a second feed terminal for a second signal of a second polarization different from the first polarization. Each radiator may be configured to contribute to resonances at two or more nonoverlapping bands. In an embodiment, the antenna may further include a third feed terminal for a third signal of the first polarization, and a fourth feed terminal for a fourth signal of the second polarization.

Disclosed are a single-frequency circular polarization positioning antenna and a wearable device. The single-frequency circular polarization positioning antenna includes an inverted F antenna and a parasitic antenna which are in an orthogonal layout; resonance is generated on the parasitic antenna through a coupling effect by means of feeding the inverted F antenna, so that the overall structure of the circular polarization antenna is simplified, and is achieved on a wearable product more easily. Therefore, the positioning antenna can better receive signals of a navigation satellite, and right hand circular polarization radiation generated by an annular radiating body can also filter left hand circular polarization navigation satellite signals reflected by high buildings or the ground, so as to reduce the multipath interference, thus effectively improving the positioning accuracy of the positioning antenna of the wearable device.
