In the modern day, wireless communications systems are widely used for medical services and medical information security. A wireless communication device for medical services is required for a high performance and small size technique. In this article, a proposed compact size of the single‐ended mixer using small size of the Wilkinson power divider with T‐shaped transmission line is presented. The compact size of the mixer used for small size is based on Wilkinson power divider using T‐shaped transmission line which is connected to amplifier circuit part. The electrical length of the transmission line for the conventional Wilkinson power divider was 90°. However, the electrical length of the T‐shaped transmission line was 30°. Therefore, the physical length was reduced by 1/2 times. The size of a proposed mixer was 22.21 × 18.32 mm 2 at a center frequency of 2.165 GHz. It will be applied to a transceiver for wireless communication system of medical services.
