A small-size high-gain 16 GHz tri-resonance bow-tie microstrip antenna

In this paper, a tri resonance edge-fed bow-tie patch antenna is designed, simulated, built and tested. The measured gains are 7.67 dB at 15.27 GHz and 10.42 dB at 16.15 GHz, representing the first demonstrated antenna with over 10 dB gain in less than 1cm size for a bow-tie microstrip structure operating at such frequencies. The resonance frequencies are chosen such that they could be used in many satellite communications applications in the 12–16 GHz band.
