Triple-Band Dielectric Resonator Antenna Based on Anisotropic and Heterogeneous Ceramics

Over the last few years, the devices in general are getting more connected to different telecommunication systems and, at the same, the space available for the antenna to provide this connectivity is getting smaller. In this context, the use of a single antenna that operates at different frequency bands with different radiating characteristics is really interesting [1], [2]. In this work, a triple-band dielectric resonator antenna (DRA) is presented, which operates at the L5 (1176.45 MHz
$\pm 10.23$
MHz) and L1 (1575.42 MHz
$\pm 10.23$
MHz) bands of the GNSS as well as the 2.4-GHz ISM band. The antenna is depicted in Fig. 1(a).
