摘要：
This paper presents a compact antenna in a circular shape with a U-shaped open-ended slot on the ground for brain-computer interface (BCI) systems. The designed antenna operates over a large frequency range of 800-4260 MHz, which encompasses Industrial, Scientific, and Medical (ISM) bands (868-868.6 MHz, 902 - 928 MHz, and 2400 - 2480 MHz) and Wireless Medical Telemetry Service (WMTS) bands (1395 MHz-1400 MHz and 1427 MHz-1432 MHz). The overall size of the recommended antenna is only 56.55 mm(3) with a thin profile of 0.5mm. A significant size miniaturization of the antenna is achieved by introducing a shoring pin and properly cutting rectangular slots on the ground. To validate the proposed antenna's performance in a real scenario, it is immersed in minced pork and the measured -10 dB bandwidth is 3465 MHz. Additionally, the radiation pattern of the antenna is characterized, which illustrates that our proposed antenna is a potential candidate for BCI systems.
