Abstract

A
new design of the micropatch antenna for GPS applications is studied. 70
antenna iterations working around the L1 band (1575 MHz) with different sized
quarter-circular slots on the patch are designed and simulated. In parallel,
“design dimensional parameters (“r” slot radius and “h” substrate thickness)
and antenna resonant frequencies according to parameters” are applied to curve
fitting algorithm and an equation for resonance frequency is obtained based on
r and h. The resonance frequency values obtained by proposed equation are compared
with simulations.

Keywords
