Abstract
Example embodiments relate to Open Ended Substrate Integrated Waveguide (OESIW) antenna arrays and techniques for manufacturing and using OESIW antenna arrays. An example antenna array includes a waveguide and a waveguide feed coupled to the waveguide. The waveguide feed is configured to couple electromagnetic energy between an external source and the waveguide. The antenna array also includes a printed circuit board (PCB) having a plurality of antenna elements. The PCB is coupled to the waveguide at a plurality of coupling points such that the electromagnetic energy propagates out from the waveguide and through the plurality of antenna elements. An OESIW antenna array can be used within a radar unit, communication system, or other type of signal emitter.
