Abstract

In this study, a novel Dual-band multiple-feed microstrip antenna is introduced for GNSS applications. The proposed antenna has a compact size of 1548
and counts as a low-cost, low-profile antenna. The mathematical equations of Multiple-Feed configuration are driven to analyze Circular Polarization (
) generation and find the effective parameters on
value. It is shown that for an n-feed symmetric antenna, the phase shift of

between ports leads to pure
, regardless of the electrical field pattern. However, if the first feed electric field has equal value in the x and y direction and also 90
phase shift, the
value is increased. A symmetric four-feed configuration is employed on the antenna to generate
. Also, fractal Circular rings and perturbing sectors are applied to miniaturize the antenna and improve the
value. Numerical simulation shows that all feeding network requirements are met and the phase shift is satisfied at both frequencies by using the coupler technique. Furthermore, results show desirable band width of 48
and 60
and high front to back ratio of 16.1 and 14 at
=1.227
and
=1.575
, respectively. The Axial Ratio (
) beam-width at both frequencies is more than 66
.
