✦ Synopsis

Abstract

A broad frequency‐band millimeter‐wave antenna working over 18–40 GHz has been designed and developed to realize low‐sidelobe fan‐beam radiation patterns. The antenna system consists of a cylindrical parabolic reflector fed by an offset double‐ridged horn antenna feed. This type of antenna finds extensive use as a rotary direction‐finding (RDF) system in electronic warfare applications. The design approach and measured results for the antenna over 18–40 GHz have been presented. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 245–248, 2001.

## Abstract A compact planar broadband millimeter‐wave antenna is presented in this article. The proposed millimeter‐wave (MM‐W) antenna is realized by connecting two pairs of open loop ring resonators (OLRRs). A tapered transmission line is adopted to improve the return loss performance in the req

## Abstract In this paper, we describe a fixed‐beam broadband planar antenna array at millimeter‐wave frequencies. The antenna is fed by waveguide‐feed and microstrip‐feed networks. In order to ensure fixed beams and a broad bandwidth, a subarray concept is introduced. For efficient coupling, a nov
