Abstract

Methods and systems for an n-phase transmitter utilizing a leaky wave antenna (LWA) are disclosed and may include transmitting an n-phase wireless signal at a first frequency via the LWA utilizing a plurality of second frequency signals from one or more signal sources, and the second frequency may be lower than the first frequency. Each of the second frequency signals may be configured with a phase difference and may be communicated to the LWA utilizing one or more power amplifiers (PAs). The PAs may be operated in switching mode, thereby generating a square wave. The LWAs may be integrated on the chip, on a package to which the chip is affixed, and/or on a printed circuit board to which the chip is affixed. Square wave signals may be generated utilizing the signal sources. The transmitted wireless signal may be amplitude modulated utilizing a bias voltage applied to the LWAs.
