Abstract
The dielectric resonator antenna (DRA) has received increasing attention in recent years. It has a number of advantages including its small size, light weight, low cost, ease of excitation, and relative wide bandwidth as compared with the patch antenna. Also, it is a volume device that offers the designer more degrees of freedom than the 2D-type antenna (e.g.microstrip antenna) or 1D-type antenna (e.g.monopole antenna).

Apart from its applications in the RF and microwave bands, the DRA is also very suitable for millimeter-wave applications because it does not have any metal portion. Its efficiency is very high even in the millimeter-wave band.
