An antenna system includes a wired communications interface, an antenna, and antenna system control circuitry. The wired communications interface is operable to couple to a serviced host device and includes a control interface and an antenna interface. The antenna couples to the antenna interface and has configurable antenna characteristics. The antenna system control circuitry couples to the control interface and to the antenna and is operable to communicate the configurable antenna characteristics to the host device and to configure the antenna based upon communication with the host device. In other constructs the antenna may not be configurable and the antenna characteristics communicated are fixed. The antenna system may further include Radio Frequency (RF) transmit circuitry and/or RF transmit circuitry. Such RF transmit circuitry and RF receive circuitry may be configurable or fixed in its operations.
