Abstract
A Printed Circuit Board (PCB) comprising various integral components and method of manufacture are provided. The PCB includes a Substrate Integrated Waveguide (SIW), integrated waveguide antennas disposed above the SIW, apertures formed in SIW for coupling with the waveguide antennas, a transmission line routed above the SIW and using the SIW as a ground plane thereof, and further antennas, integrated into the PCB and disposed above and coupled to the transmission line. The SIW and the transmission line may be branched structures for feeding corresponding arrays of waveguide antennas and further antennas. Coplanar waveguides may also be integrated into the PCB and coupled to the SIW and the transmission line via integral impedance matching structures. PCB feature re-use and component interleaving may provide for a desirable and manufacturable PCB structure.
