Abstract

In this paper we fabricated QMSAs for 850MHz band on the teflon substrate with $\varepsilon_1-2.6, $ $t=1.6mm(\pm0.08)(CGP-500).$ We measured the resonant frequency and the return loss with cutting the gap region between radiation patch and ground plate by a 5mm length step by step. As a result we found that the measured data was not so bad unlike other papers when the gap region was closer to zero, especially under 10mm.
