A Compact Dual Resonant Leaky Wave Rectangular Dielectric Resonator Antenna (LWRDRA) With Extended Bandwidth

A novel technique for producing enhanced band width in micro and mm wave region of spectrum is presented. A new design of compact & broadband leaky wave dielectric resonator antenna is proposed using co-axially probe feed technique. Two different LWDRA are designed and their characteristic behaviors are compared. Finally, parametric study of Second Antenna has been done. With the proper design the resonant behavior of the antenna is found, over which the leaky wave DRA produces extended bandwidth. Numerous designs for the LWRDRA are simulated and bandwidths exceeding 20% are achieved.
