Patent ID: 8489041

Claim:
A predistortion compensated transmitter and antenna system, comprising: an input for receiving a digital input communication signal; a digital radio receiving the digital input communication signal and providing an RF signal; a first amplitude and phase adjusting network receiving the RF signal and providing a first adjusted RF signal; a first predistorter receiving the first adjusted RF signal and performing a first predistortion operation on the first adjusted RF signal and providing a first predistorted RF signal; a first amplifier having a first amplifier input coupled directly to an output of the first predistorter receiving and amplifying the first predistorted RF signal and providing a first amplified RF signal; a first radiating element electrically coupled to receive the first amplified RF signal; a second amplitude and phase adjusting network receiving the RF signal and providing a second adjusted RF signal; a second predistorter receiving the second adjusted RF signal and performing a second predistortion operation on the second adjusted RF signal and providing a second predistorted RF signal; a second amplifier having a second amplifier input coupled directly to an output of the second predistorter receiving and amplifying the second predistorted RF signal and providing a second amplified RF signal; and a second radiating element electrically coupled to receive the second amplified RF signal, wherein the first and second radiating elements are positioned in a common column, wherein the digital radio, the first and second amplitude and phase adjusting network, the first and second predistorter, the first and second amplifier, and the first and second radiating element are configured at an antenna radiating location in close proximity with each other.
