In this letter, a patch antenna on a photonic bandgap substrate is presented. A reduction in the le¨el of surface-wa¨e mode excitation has been obtained. This leads to impro¨ed efficiency, gain, and far-field radiation pattern. Furthermore, impro¨ements in the input return loss ha¨e been reported.

## Abstract In this paper, a Van Koch printed antenna on a photonic‐bandgap fractal substrate is presented. The substrate is designed with grounded Van Koch printed elements. The structure is a multifrequency radiator as a common fractal antenna, but the special synthesis of the substrate enhances
