ABSTRACT:
A microstrip antenna or other microstrip device has a planar electrically-conductive region on the surface of a dielectric board. The device is tuned by silk-screen printing one or more layers of a dielectric ink/paint over the surface of the device. This produces layers of a predetermined thickness which each reduce the frequency of tuning of the device by a predetermined amount until the desired frequency is achieved.
