Abstract :
The design and development of a Rotman lens for operation at 94 GHz which feeds an antenna array for beamsteering applications is presented. The construction is completely realised in waveguide technology. The lens consists of 15 beam ports covering a scan range of ±23.3° in steps of 3.3° and 10 array ports connected via phase compensating transmission lines to a linear antenna array. Experimental results are compared with theoretical calculations.
