A low profile compact vehicle-based antenna for dual-band wireless network communication systems

In this paper, a compact integrated dual-band dielectric resonator antenna (DRA) is proposed. This structure uses the combination of a thin rectangular DR and a L-shaped microstrip line, and the L-shaped microstrip line performs as a radiator and a feed to the DR. With the optimized structure parameters, the DRA resonates at a lower band and the L-shaped works a higher band, and the antenna radiates in conical like patterns at the two bands. The proposed design can find its applications in wireless communication systems, especially for vehicle-based antennas, where null radiation is in the broadside direction
