A Coplanar Waveguide Rectangular Dielectric Resonator Antenna (RDRA) for 4G Applications

This paper presents the design of coplanar waveguide (cpw) rectangular dielectric resonator antenna (rdra) with and without metallic strip, operating at 2.6 ghz for long term evolution (lte) applications. the cpw rdra without metallic strip produces impedance bandwidth of 51 %. then, a metallic strip was added on top of the dielectric resonator (dr) in order to enhance the impedance bandwidth; thus give more flexibility for the system to cover more applications. a good agreement between simulation and measurement results, in terms of reflection coefficient magnitude and radiation pattern is presented. the simulated and measured impedance bws for s11 < -6db are 67 % (1.74-3.47 ghz) and 66 % (1.83-3.54 ghz) respectively, with the gain of 3.12 dbi is obtained at 2.6 ghz. the mode excited for this antenna is tey1δ1 mode.
