Abstract

In this article, a low‐loss parallel‐series feed structure using substrate integrated waveguide (SIW) technology for a single‐layer microstrip antenna array is presented. In addition to reduction of feed radiation, the feed network benefits from typical advantages of planar structures such as compactness, low cost, integrability, and mass‐producibility. A 2 × 8 microstrip antenna array of size 109 mm × 34 mm fed by the proposed SIW feed system is designed and fabricated. Measurements on the fabricated array verify a minimum gain of 17.5 dBi in the frequency range of 17.4 to 18 GHz. © 2009 Wiley Periodicals, Inc.

## 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
