摘要： An antenna apparatus and an electronic apparatus are provided. The electronic apparatus includes the antenna apparatus. The antenna apparatus includes a radiator, a first and a second impedance control circuit. The radiator receives and transmits a radio frequency (RF) signal. The first impedance control circuit is electrically connected to the radiator and transmits the RF signal. The second impedance control circuit includes an impedance matching circuit and an inductor. The first end of the impedance matching circuit is electrically connected to the radiator. The impedance matching circuit adjusts the impedance matching of the radiator and transmits a sensing signal. The inductor is electrically connected to the second end of the impedance matching circuit. The inductor transmits a sensing signal, and blocks the RF signal. Accordingly, the structures of the antenna and the circuit can be simplified, and the influence between the RF signal and the sensing signal can be reduced.

摘要： Base station antennas include a plurality of multiplexer filters and a multi-column array of radiating elements that includes a plurality of sub-arrays. Each filter may have a first and second ports that are configured to pass RF signals in respective first and second frequency bands and a third common port that is coupled to a respective one of a plurality of sub-arrays. These antennas also include first frequency band ports that are coupled to the first ports of respective subsets of the multiplexer filters and second frequency band ports that are coupled to the second ports of at least some of the multiplexer filters. The antenna may operate as a MIMO sector antenna in the first frequency band and as a sector-splitting antenna in the second frequency band.
