Abstract :
This paper presents an overview of the multi-path phenomena and the performance of the shorted annular patch (SAP) in suppressing unwanted multi-path signals caused by ground reflections. It is shown that the SAP´s previously derived multi-path suppressing optimum is in fact sub-optimal. An improved design rule based on the multi-path ratio (MPR) is proposed.
