Abstract :
This article shows a printed circuit lens fed multiple beam antenna array designed for millimeter wave indoor personal communication systems, which is formed by using of a linear array of equally spaced elements, fed with an improved printed circuit Rotman lens. Both the lens and the array are designed and built on the same dielectric substrate. The antenna operates in frequency range of 27-30 GHz and covers an angular sector near 120 degrees with 11 beams. A full azimuth coverage can be obtained through a set of three antenna arrays. Simulation results of phase and amplitude distributions, radiation pattern prediction as well as application considerations are given.
