Abstract

This letter presents an antenna configuration to achieve a coupling reduction between colocated antennas. Application of an adaptive spatial notch enables this functionality. Analytical results are obtained, which show good resemblance to simulated and measured results, performed on a prototype manufactured to operate around 2.5 GHz. Coupling reduction of 50 dB has been measured. The antenna impedance is also influenced because of this configuration and shows an S11 better than - 15 dB at the frequency of interest. In addition, the radiation pattern of both antennas is influenced. This can be seen as an advantage or a disadvantage, depending on the application.
