摘要：

The modeling and design of a new substrate integrated waveguide (SIW) series-fed dielectric resonator antenna (DRA) parasitic array are presented. Parasitic DRAs are added on both sides of each active element of a DRA fed by longitudinal slot on SIW. The E-coupling mechanism between a driven DRA and two parasitic DRA elements with low dielectric constant is discussed. Also, the impact of the coupling gap on reflection coefficient, impedance bandwidth, and gain and radiation pattern is presented. A four-element antenna array operating at the millimeter-wave band (36-39 GHz) is designed and fabricated. The measured radiation pattern demonstrates a broadside beam with a maximum gain of 12 dBi over an impedance bandwidth (with vertical bar S-11 vertical bar < -10 dB) of 3.3 GHz.
