Abstract:
The improved version of a broadband microstrip‐to‐slotline transition is presented. The transition consists of a microstrip radial stub, a slot radial stub, and a multisection matching transformer. An extremely large angle slot radial stub is introduced into the design to reduce radiation loss and maximize the field converting around the microstrip‐slotline tee junction. From experimental results, the improved transition has greater bandwidth and lower loss than the earlier designs. With the return loss of better than 15 dB, the 1‐ and 3‐dB back‐to‐back insertion loss bandwidth can cover from 1.04 to 5.13 GHz (1 : 4.9) and from 1.02 to 13.90 GHz (1:13.6), respectively. The proposed planar transition has the advantages of compact size, wide bandwidth, simple structure, and straightforward design procedure. © 2009 Wiley Periodicals, Inc.
