研究了2.4 GHz紧凑型短路贴片天线在有耗介质附近的阻抗和辐射特性。在这项研究中，研究了一种在2.4 GHz下介电常数和电导率接近人类躯干或手臂的有损耗介质。结果表明，当天线放置在非常靠近（仅1 mm间距）有损介质时，天线仍然可以提供可接受的工作带宽（> 84 MHz，覆盖2.4-GHz WLAN频段）和效率（> 60%）。结果表明，研究的紧凑型短路贴片天线是有希望的应用程序作为一个身体佩戴在身体上的天线。© 2005 Wiley Periodicals，Inc.

Impedance and radiation characteristics of a 2.4‐GHz compact shorted‐patch antenna in close proximity to a lossy medium are investigated. In this study, a lossy medium with permittivity and conductivity close to those of a human torso or arm at 2.4 GHz is studied. The results obtained show that the antenna can still provide acceptable operating bandwidth (> 84 MHz covering the 2.4‐GHz WLAN band) and efficiency (> 60%) when the antenna is placed very close (1‐mm spacing only) to the lossy medium. The results indicate that the compact shorted‐patch antenna studied is promising for application as a body‐worn antenna on the body. © 2005 Wiley Periodicals, Inc.
