Abstract

Methods and systems for a multi-port distributed antenna are disclosed and may include configuring one or more amplifiers to communicate signals via one or more ports on a distributed antenna. A characteristic impedance of the distributed antenna at each of the one or more ports may be configured by a location of the one or more ports on the distributed antenna. The amplifiers may be impedance matched to the distributed antenna by coupling each of the amplifiers to the ports based on the characteristic impedance. The amplifiers may include power amplifiers and/or low noise amplifiers. The signals may be time division duplexed. The signals communicated via the ports on the distributed antenna may include RF signals. The distributed antenna may be integrated on a chip with the amplifiers or may be located external to a chip with the amplifiers. The distributed antenna may include a microstrip antenna.
