Abstract
We present a novel endfire antenna based on asymmetric spoof surface plasmon polaritons (SSPPs) and phase-reversal technique. SSPPs structure allows it to be fabricated on a single-layer printed circuit board. Asymmetric SSPPs elements were employed to fulfill the condition of endfire radiation, and meanwhile, phase-reversal technique provides a high gain for the antenna. To verify the proposed design principle, a prototype was fabricated and measured. It exhibits a peak gain of 16.2 dBi within the operational frequency band of 17–19 GHz, featuring the highest endfire gain among all single-layer designs.
