Abstract:
In analogy to dielectric superstrate structures, a periodic array of patches printed on a single substrate is used to achieve the necessary resonance condition to considerably improve the gain of a small radiating element. An antenna of this kind was designed for the 38 GHz frequency range, built and tested. The substrate has a diameter of 100 mm and is placed 4 mm or 8 mm in front of a simple waveguide feed, resulting in a beamwidth of 7.5°, i.e. an effective aperture of about 65 mm, a bandwidth of 300 MHz and a gain of 26.3 dB.
