An active mmWave antenna based on tunable zero-mode resonances

Abstract

An active millimeter wave (mmWave) antenna with tunable zero-mode [1] resonances is proposed in this paper. Based on the zero-mode theory, shorting pins are employed to the patch antenna so as to produce TM10 and the zero modes. Particularly, PIN diodes is utilized as the switch for tuning these resonances upwardly or downwardly, thereby obtaining a wide bandwidth from 24.3-28.8 GHz on the 0.508 mm thick substrate. This proposed antenna can be applied to B5G/6G scenarios wherever mmWave bands are needed.
