Claim 0:
1. An apparatus for correcting a deviation between a plurality of transmission channels that comprises a first transmission channel and a second transmission channel, the apparatus comprising:
a first antenna corresponding to the first transmission channel;
a second antenna corresponding to the second transmission channel;
a third antenna corresponding to a third transmission channel;
a fourth antenna corresponding to a fourth transmission channel;
a first splitter located at a symmetrical position between the first antenna and the second antenna and configured to feed a first signal onto the first antenna and the second antenna; and
a vector detector coupled to the first splitter and configured to detect, when the first splitter feeds the first signal, a first signal vector based on a first feedback signal from the first transmission channel and a second signal vector based on a second feedback signal from the second transmission channel,
wherein the first signal vector and the second signal vector are for determining a first deviation correction value between the first transmission channel and the second transmission channel,
wherein the first deviation correction value is for correcting a deviation between the first transmission channel and the second transmission channel,
wherein the transmission channels further comprise a first correction coupling channel and a second correction coupling channel, wherein a first endpoint of the first correction coupling channel is coupled to the first antenna, wherein a second endpoint of the second correction coupling channel is coupled to the second antenna, and wherein the first splitter is further configured to:
further feed the first signal onto the first transmission channel through the first endpoint; and
further feed the first signal onto the second transmission channel through the second endpoint;

wherein the third antenna is coupled to a third endpoint of the first correction coupling channel,
wherein the fourth antenna is coupled to a fourth endpoint of the second correction coupling channel,
wherein the first correction coupling channel is configured to feed the first signal onto the third transmission channel through the third endpoint,
wherein the second correction coupling channel is configured to feed the first signal onto the fourth transmission channel through the fourth endpoint, and
wherein the vector detector is further configured to:
detect a third signal vector based on a third feedback signal from the third transmission channel when the first signal is fed onto the third transmission channel; and
detect a fourth signal vector based on a fourth feedback signal from the fourth transmission channel when the first signal is fed onto the fourth transmission channel,
wherein the third signal vector and the fourth signal vector determine a second deviation correction value between the third transmission channel and the fourth transmission channel, and
wherein the second deviation correction value is for correcting a deviation between the third transmission channel and the fourth transmission channel.
