Method and apparatus for increasing rfid read range in daisy chain configuration

A repeating switch antenna comprising:

• a transmission signal amplifier configured to amplify a transmission signal based on a power control signal;
• a first coupler configured to receive (i) the amplified transmission signal, (ii) a reception signal, and (iii) a load impedance;
• a noise cancelation circuit configured to generate the load impedance based on an in-phase channel input and a quadrature channel input;
• a digital acquisition system (DAS) configured to (i) generate the power control signal, (ii) generate the in-phase channel input and the quadrature channel input, and (iii) generate a select signal;
• reception signal amplifier configured to receive the reception signal from the first coupler and amplify the reception signal;
• a first radio frequency (RF) connector configured to receive the transmission signal and the amplified reception signal via a second coupler;
• a second RF connector configured to transmit the amplified transmission signal;
• and,
• a RF switch configured to (i) route the amplified transmission signal from the first coupler to the second RF connector or to an antenna based on the select signal, and (ii) route the reception signal to the first coupler.
