This paper presents a review of the Computer-Aided Microwave Design System (CAMDS) as originally developed by Divya Bais. Its goal was to deal with microwave design and analysis problems presented in standard textbooks such as David Pozar’s Microwave Engineering. This work presents improvements to CAMDS and verifies its performance. The paper focusses on passive devices using microstrip transmission lines such as filters or stub tuners. Designs developed with CAMDS are compared with those reported by Pozar, simulated using the Agilent Advanced Design System (ADS), and then fabricated using an ADS layout. In appropriate cases, device performance is checked using independent computer analysis or measurement of the device response using a microwave network analyzer. The main results are an improved version of CAMDS and rigorous verification of its capabilities to produce useful designs for practical passive microwave devices.
