Design algorithm of multi-segment dielectric resonator antennas (MSDRA)

This paper introduces a simple design algorithm for MSDRAs. The algorithm avoids prior time consuming trial and error processes for achieving the optimum parameters of MSDRA and gives an antenna with best possible impedance bandwidth in desired feedline-MSDRA coupling. To show the efficiency of the algorithm, two examples are examined in X-band. The examples are simulated using two numerical methods. Then adjusting the position of the MSDRA with respect to the open end of the microstrip line is proposed to maximize the feedline-MSDRA coupling.
