Methods and systems for an integrated leaky wave antenna-based transmitter and on-chip power distribution are disclosed, and may include supplying one or more bias voltages and ground for a chip including a plurality of power amplifiers (PAs) utilizing bias voltage and ground lines. One or more leaky wave antennas (LWAs) may be communicatively coupled to the power amplifiers. Wireless signals may be transmitted utilizing the LWAs integrated in the lines in the chip. Radio frequency (RF) signals may be transmitted via the plurality of LWAs. The RF signals may include 60 GHz signals and the LWAs may include microstrip and/or coplanar waveguides. A cavity length of the LWAs may be configured by a spacing between conductive lines in the microstrip and/or coplanar waveguides. The LWAs may be configured to transmit the wireless signals at a desired angle from a surface of the chip.
