The posterolateral region of the knee has a complex and diverse anatomy. Hydrarthrosis of the knee can potentially communicate with other parts of the joint space. The joint fluid distribution reflects anatomical communications between synovial spaces. To observe the continuity between the knee joint cavity and the surrounding bursa, we devised a dissection method with a new injection agent, an eosin‐containing...
Authors have proposed a printed inverted-F antenna (PIFA) for circular polarization. In this paper, an approach to improve the bandwidth is investigated. It is shown that the bandwidth can be widened by designing the rectangular element loaded at the feeding line as short as possible. The redesigned PIFA in this paper has approximately twice (210MHz) the bandwidth of the 3dB-axial ratio with a 10dB-return...
