LOW PROFILE DIELECTRIC RESONATOR ANTENNA BACKED BY SUBSTRATE INTEGRATED WAVEGUIDE CAVITY
View through CrossRef
A low-profile dielectric resonator antenna backed by substrate integrated waveguide cavity is proposed in this paper. A novel feeding mechanism is used to excite a low-profile dielectric resonator antenna backed by substrate integrated waveguide cavity. Instead of a single slot, a 2x2 array of 2mm x 2mm slots is used to excite the dielectric resonator antenna. With this feeding technique, an antenna working in X band frequencies is designed by combining substrate integrated waveguide cavity and dielectric resonator antenna resonant modes. The paper compares the conventional single slot excited dielectric resonator antenna and the proposed 2x2 slot array excited dielectric resonator antenna. The proposed antenna is linearly polarized with a 2:1 VSWR bandwidth of 5.3% and a peak gain of 6.5dBi. Overall dimension of the antenna is 30mm x 30mm x 0.78mm.
