We present a miniaturized antenna applied for biomedical applications. The key to communicate with the external devices is the antenna design. Meanwhile, a multilayered PIFA antenna operating at 433MHz industrial, scientific and medical (ISM) band with the gain of −28dBi is proposed. In antenna simulation, we simulate the antenna inside capsule system composed of capsule shell, and circuit equivalent...
A communication well is a well digged underground for data communication with base station using a specific antenna. To use communication wells, there is a need to design the specific antenna working at 836 MHz and 881 MHz frequency with each bandwidth of 50 MHz. The antenna should be embedded on the side of the well so that it does not take much room and the antenna should have a certain radiation...
A novel planar Coaxial Collinear (COCO) antenna with rectangular coaxial strip is presented. The planar COCO antenna is fed by microstrip and comprises several radiation sections of rectangular coaxial strips which are cross-linked one by one. A prototype has been designed and fabricated to cover the band of 2.4–2.48 GHz. The simulated and measured results show that the fractional −10 dB bandwidth...
