An antenna system can include casing-side antennas and a full wave rectifier. The casing-side antennas can be coupled to a casing string that is positioned in a wellbore for communicatively coupling to a tubing-side antenna positioned in the wellbore. Each of the casing-side antennas can include a conductive wire positioned to carry current that can be induced on the conductive wire in response to an electromagnetic field from the tubing-side antenna. A direction, relative to a common antenna junction point, of the current on the conductive wire can be opposite to the direction, relative to the common antenna junction point, in which an adjacent casing-side antenna is positioned to carry current induced in response to the electromagnetic field. The full-wave rectifier can be conductively coupled to the casing-side antennas for converting alternating current that can be generated on the casing-side antennas into direct current.
