- 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. (C) 2003 Wiley Periodicals, Inc.
