Abstract
A multiple input, multiple output, MIMO, antenna arrangement comprising: a transmit hybrid circuit connected to receive first and second transmit signals, and to output a sum of the first and second transmit signals, and to output a difference of the first and second transmit signals, a first antenna connected to receive the output sum; a second antenna connected to receive the output difference; a receive hybrid circuit connected to receive signals from the first and second antennas, and to output a sum of the signals from the first and second antennas, and to output a difference of the first and second antenna signals; a first cancellation circuit connected to receive the first transmit signal and configured to compensate for the interference due to the first transmit path; a second cancellation circuit connected to receive the second transmit signal and configured to compensate for the interference due to the second transmit path; wherein: the sum output of the receive hybrid circuit and the output of the first cancellation circuit are combined to generate a first receive signal; and the difference output of the receive hybrid circuit and the output of the second cancellation circuit are combined to generate a second receive signal.
