            Abstract : 
This paper reports the architecture of a five-port receiver without vector base circuit generators in which three antennas provide three phase-shifted copies of the received signal. A 2.4 GHz prototype was implemented for concept proofing and the measurements point to a 6 dB higher sensibility with respect to comparable classic five-port receivers.
