High Performance Dual-Band Antenna Using Rogers Magneto-Dielectric Material for GNSS Band

Here, we show a unique dual-band circularly polarized patch antenna operating in GNSS band by using the magneto-dielectric material that Rogers is developing for L-band communication applications. The improved performances like miniaturization, efficiency and bandwidth were achieved by using materials with
$\boldsymbol{\varepsilon}_{\mathbf{r}} > \mathbf{1};\boldsymbol{\mu}_{\mathbf{r}} > \mathbf{1}$
as well as low dielectric and magnetic loss tangents which help to improve the gain of an antenna over the desired lower and upper GNSS frequency band.
