The west Sweden region is a leading European node for research, development and business in microwave technology.
It all started some fifty years ago when a development and production plant for radars mainly for defence was set up.
The present largest regional microwave employers are Saab and Ericsson.
The division Saab Microwave Systems is developing state of art radar systems for defence applications.
Ericsson has research and development of cellular radio base stations and microwave radio links .
Radio links produced at the Ericsson plant in Borås supply 40% of the global market.
Ruag Aerospace Sweden is the largest Swedish-based space company where microwave technology is one key part of the high-tech equipment being produced.
Several advanced test and development support institutes such as SP - Technical Research Institute of Sweden, SwereaIVF and Swedish ICT  are based in the region.

Arkivator is a large producer of antennas and telecom component.
Entrepreneurship is strong in the region and support many small enterprises and growing start-ups in the microwave business such as microwave sensor systems for space (Omnisys Instruments), microwave detection of foreign bodies in food (Foodradar Systems),  medical microwave imaging (Medfield diagnostics) and antenna test systems (Bluetest).
Chalmers University of Technology in Göteborg is internationally recognised for research on future information and communication technologies where microwave technology, antennas and communication systems constitute some of the strongest scientific and educational profiles.
