Abstract: This application provides an antenna structure and a communications terminal. The antenna structure includes an antenna radiator, a signal source, a first capacitor, and a first tuning circuit. A first terminal of the antenna radiator is grounded. A first terminal of the first capacitor and a first terminal of the first tuning circuit are electrically connected to a connection point of the antenna radiator. A second terminal of the first capacitor is electrically connected to the signal source. A second terminal of the first tuning circuit is grounded. Antenna impedance of the first terminal of the first capacitor at target frequencies is in the first quadrant of a Smith chart, and the target frequencies are at least some frequencies in frequency bands covered by the antenna radiator.
Abstract: An electronic device may be provided with a phased antenna array on an antenna module. The array may include low band antennas and high band antennas that radiate at frequencies greater than 10 GHz. The module may include antenna layers, transmission line layers, and ground traces that separate the antenna layers from the transmission line layers. The low band antennas and the high band antennas may have radiators patterned onto the antenna layers. The radiators may be fed by transmission lines on the transmission line layers. The antenna layers may have a dielectric permittivity that is greater than the dielectric permittivity of the transmission line layers. This may serve to reduce the lateral footprint of the low band and high band antennas, which allows the antennas to be interleaved along a common linear axis in the phased antenna array, thereby minimizing the lateral footprint of the antenna module.

Abstract: A GPS reception arrangement includes a GPS radome body having an upper body portion, a lower body portion and a peripheral body portion between the upper body portion and the lower body portion and extending circumferentially there around, and a GPS antenna positioned inside the radome body. A plurality of light sources on the peripheral body portion of the radome body project light in a manner to identify the GPS radome, and distinguish it from other radomes. Retroreflective material is positioned around the radome body on the peripheral body portion, adjacent the plurality of light sources.
