Abstract
A multi‐pole gap‐coupled unidirectional dielectric radiator (UDR) is proposed for broadband applications in the millimeter‐wave band. The advantages of gap‐coupled UDR include ease of planar integration, low loss, and low cost. Design parameters of the gap‐coupled UDR, such as resonator length and gap distance, are determined using an equivalent circuit model of an evanescent nonradiative dielectric (NRD) guide. Prototypes of the gap‐coupled UDR are designed and measured at 38 GHz. The measured results show good agreement with simulated data. © 2003 Wiley Periodicals, Inc.
