1. An apparatus, comprising:
- a first antenna coupled to a first radio frequency (RF) circuit to receive or transmit RF signals;
a second antenna coupled to a second RF circuit to receive or transmit RF signals;
a first RF current blocker, comprising a first slot line radial stub, disposed between the first and second antennas; and
a second RF current blocker, comprising a second slot line radial stub, disposed between the first and second antennas,wherein the first and second RF current blockers increase isolation between the first and second antennas.

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.
