Multiple frequency antenna array for use with an RF transmitter or transceiver
First Claim
1. A radio frequency (RF) transceiver comprises:
- up-conversion module coupled to convert an outbound signal into outbound RF signal;
power amplifier module coupled to;
produce a first representation of the outbound RF signal at a first transmit carrier frequency for transmission from a first antenna, wherein the first transmit carrier frequency corresponds to a carrier frequency of the outbound RF signal offset by a first transmit frequency offset; and
produce a second representation of the outbound RF signal at a second transmit carrier frequency for transmission from a second antenna, wherein the second transmit carrier frequency corresponds to the carrier frequency of the outbound RF signal offset by a second transmit frequency offset, and wherein the first transmit frequency offset and the second transmit frequency offset have frequency offset values to maintain the first transmit carrier frequency and the second transmit carrier frequency within a bandwidth of the outbound RF signal, but have sufficient frequency separation to inhibit nulling of an antenna pattern generated from the first and second antennas in transmitting the first and second representations of the outbound RF signal;
a low noise amplifier module coupled to;
receive a first representation of an inbound RF signal at a first receive carrier frequency at the first antenna, wherein the first receive carrier frequency corresponds to a carrier frequency of the inbound RF signal offset by a first receive frequency offset;
receive a second representation of the inbound RF signal at a second receive carrier frequency at the second antenna, wherein the second receive carrier frequency corresponds to the carrier frequency of the inbound RF signal offset by a second receive frequency offset, and wherein the first receive frequency offset and the second receive frequency offset have frequency offset values to maintain the first receive carrier frequency and the second receive carrier frequency within a bandwidth of the inbound RF signal, but have sufficient frequency separation to inhibit nulling of the first and second representations of the inbound RF signal; and
produce the inbound RF signal from the first and second representations of the inbound RF signal; and
a down conversion module coupled to convert the inbound RF signal into an inbound signal.

Abstract
A multiple frequency antenna array includes a first antenna circuit and a second antenna circuit. The first antenna circuit has a first radiation pattern and is tuned to a first carrier frequency. The first antenna circuit transmits a first representation of a radio frequency (RF) signal at the first carrier frequency, where the first carrier frequency corresponds to a carrier frequency of the RF signal and a first frequency offset. The second antenna circuit has a second radiation pattern and is tuned to a second carrier frequency. The second antenna circuit transmits a second representation of the RF signal at the second carrier frequency, where the second carrier frequency corresponds to the carrier frequency of the RF signal and a second frequency offset.
