A 38 GHz MICROSTRIP ARRAY WITH AN E-PLANE WAVEGUIDE FEEDING NETWORK
A 38 GHz MICROSTRIP ARRAY WITH AN E-PLANE WAVEGUIDE FEEDING NETWORK Wolfgang Menzel, Marc Schreiner Microwave Techniques, University of Ulm, PO Box, D-89069 Ulm, Germany Abstract A major restriction of high gain microstrip antenna arrays is found in their high losses, mainly due to the feeding network. In this contribution, design and results of a 38 GHz microstrip array antenna with a low-los
