Dual mode and miniaturized rectangular dielectric resonator antenna with a simple feeding scheme
The objective of this article is to propose a miniaturized rectangular dielectric resonator antenna (RDRA) configuration and dual mode operation using a simple feeding scheme. It demonstrates the potential advantages achieved by choosing a microstrip line feeding mechanism at the edge of the RDRA. Measurement and simulation results are both in good agreement. The fabricated antenna possesses wide impedance bandwidth (BW) of 800 MHz (5.65 to 6.48 GHz) and dimensions of RDRA are 17  7  3 mm3. Measured radiation patterns have linear polarization over the frequency range. By the proposed design, the BW is enhanced more than four times as compared to the conventional way to excite the RDRA by microstrip line. To validate the design, the comparison of published design is discussed.  2014 Wiley Periodicals, Inc. Int J RF and Microwave CAE 25:229235, 2015.
