Abstract
Simulation and experimental results of substrate integrated waveguide (SIW)-integrated 2-D dielectric resonator antenna (DRA) array operating at millimeter-wave frequency band are presented. The antenna array consists of 64 elements arranged in 8 ×8. Hybrid feeding network combining series-fed and corporate-fed is used to provide a uniform power distribution over the entire aperture of the array. The antenna array is fabricated and tested. The measured reflection coefficient shows an impedance bandwidth ( S11 ≤ - 10 dB) of 2 GHz and a measured gain of 21.60 dB over the operating frequency band 35-37 GHz. A very good correlation between the measured results and simulated results is observed.
