“…The dielectric resonator antenna (DRA) has received increasing attention because of its attractive features such as small size, low cost, versatile and flexible excitation techniques, wider impedance bandwidth, high radiation efficiency, high temperature tolerance [1][2][3][4][5]. DRA can be excited by different feeding mechanisms such as direct microstrip line feed [6,7], co-axial probe [8], aperture coupled by microstripline or coplanar waveguide [9][10][11], conformal strip feed [12] and designed with various shapes.…”

Abstract-A novel (2 × 2) high gain circularly polarized rectangular dielectric resonator antenna array integrated with helical-like exciter is proposed. The array offers a maximum gain of 12.9 dBi at the operating frequency. The circular polarization is obtained by incorporating helical-like exciter in the array structure. A prototype of the proposed configuration integrated with helical-like exciter has been fabricated and tested, and the idea has been verified. A good agreement has been obtained between the measured and simulated results.

“…Another MOM numerical study of split cylindrical dielectric resonator antennas on a conducting ground plane excited by a coaxial probe with a bandwidth of 35% is previously presented in [12]. In addition, the other analytical simulations on the various DRAs were presented in [13,14]. In these studies, not only, the analyses on the DRA with multiband operation have been not done, but also, the majority of the used dielectrics have low permittivity which simplifies the design.…”

Abstract-A novel complex structure of Printed Dielectric Resonator Monopole Antenna (PDRMA) with multi-bands operation is presented and investigated. In the proposed structure, a printed fork-like stepped monopole antenna is used for exciting two new modified hemicylindrical dielectric resonators with a great relative permittivity of 80. A narrow medium substrate with a low permittivity is also applied between two mentioned dielectric resonators and the monopole antenna, to improve the matching, especially at the lower frequencies. By using this novel designed antenna applying two dielectric resonators with very high permittivity, many frequency wide bands for VSWR < 2 are practically measured and supported which are as follows: 1

“…Dielectric Resonator Antennas (DRAs) are good candidates for many communication applications, because of their favorable characteristics, such as light weight, compact structure, wideband response, control of antenna dimensions with the value of dielectric constant, low metallic loss and prevention of surface wave propagation [1][2][3][4][5]. They are suitable substitutions for compact antennas, such as microstrip antennas.…”

Abstract-A dielectric resonator loaded patch antenna excited by a coaxial cable is proposed in this paper. The results from measurement show a wide impedance bandwidth of 57.1% from 3.75 GHz to 6.75 GHz and a peak gain of 11.5 dB at the center of frequency band with an average gain improvement of 3 dB over the frequency band in comparison with the common dielectric resonator antennas. These results are in good agreement with those obtained by the computer simulations. A simple study of the antenna shows that the aperture size increase is the cause of gain enhancement. A theoretical model based on the simulated gain results of reference antenna and its equivalent aperture is presented for the proposed antenna structure with good agreement with simulation and measurement results. The advantages of the proposed antenna are high gain with broad bandwidth, and low fabrication cost in comparison to other types of high gain DRAs having narrow bandwidths and complex structures.
