Abstract

This Letter deals with millimeter microstrip/thick‐slot/microstrip transitions. This kind of transition permits multilayer microstrip antenna arrays to feed. The objectives were to develop and to optimize this transition at 60 GHz, with the use of a low‐loss, low‐cost substrate. A thick ground plane with a slot is introduced between the two substrate layers to rigidify the final structure. Then several transitions were realized and measured in the 60‐GHz band to validate the calculation. © 2002 Wiley Periodicals, Inc.

## Abstract The purpose of this paper is to report on a microstrip reconfigurable antenna in the millimeter‐wave range. This antenna has directivity diversity and is based on a four‐element array. An original method is outlined to guarantee matching for each configuration without changing circuit.
