Abstract :
A steerable 4times1 array of quasi-Yagi endfire radiators is developed for use at 5.8 GHz. The antenna utilizes a novel dielectric phase shifting technique, previously presented by Y. Kuga and J. Cha (2004). The electrical characteristics and far field patterns are numerically approximated using Ansoft HFSS and Designer. The 4times1 array is fabricated and tested on low-cost IS620 substrate.
