ResumenThis paper presents the design and development of a waveguide fed microstrip patch antenna for Ku band applications. A circular patch is fed by using a conventional WR-51 rectangular waveguide ended with a feeding slot capacitively coupled to the radiating patch. The design is optimized using the electromagnetic software CST Microwave Studio. The antenna is fabricated and the measured results are compared with simulations. The achieved bandwidth of the manufactured antenna is approximately 16.2 - 18.4 GHz, and a maximum gain of 5.7 dBi. The comparison of measured and simulated results shows good agreement except in the prediction of the surface wave effects propagated in the antenna substrate.
