Abstract
In this paper, a microstrip array antenna utilized a subarray with a waveguide slot feeding is presented. This subarray can reduce the feed loss compared with a full microstrip feed network. The subarray has been designed both for a broad reflection bandwidth and a flat gain bandwidth from 40.5 GHz to 43.5 GHz. The 24${\times}$24 series-fed array antenna has been implemented with the maximum gain of 32.4 dBi.
