Abstract
An apparatus includes a first antenna coupled to a first radio frequency (RF) circuit to receive or transmit RF signals, and a second antenna coupled to a second RF circuit to receive or transmit RF signals. The apparatus further includes a first RF current blocker disposed between the first and second antennas, and a second RF current blocker disposed between the first and second antennas. The first and second RF current blockers increase isolation between the first and second antennas.
