Abstract
This work investigates the use of substrate integrated waveguide fed open slot antenna (WOSA) in an array for the first time to provide a new SIW slot antenna array with wide bandwidth and single-layer structure. The antenna array consists of 4 × 2 substrate integrated WOSA elements as a radiating part and two 1-to-4 SIW power dividers as the feeding network. The whole array is differentially fed and built on a single-layered laminate. To demonstrate the wideband performance of the substrate integrated WOSA elements, two sets of feeding networks designed at different frequencies are used to feed the same radiating part. In this way, a V-band and a W-band array were built. Both the antenna arrays were fabricated and measured. Benefiting from the excellent performance of the substrate integrated WOSA elements, the antenna array achieves a wide bandwidth of 32.3% (54.0 to 74.8 GHz) with a peak gain varies from 11.3 to 15.6 dBi. It has been demonstrated that the substrate integrated WOSA array can achieve a wide bandwidth with a single-layer structure, which is attractive for millimeter-wave applications.
