    • A method and apparatus for selective shielding of fabric antennas incorporates the fabric antenna (12) into the body (10) of wearable garments (30) and provides protection for wearers of the garment while allowing wearers to displace a portion of the garment body (22,24) selectively, so as to render the antenna (12) active or inactive. To protect wearers of the garment from the RF field that may be generated when an antenna is in use, a metallic fabric shielding layer is positioned in the body of the garment between the antenna and the body of a wearer. Another layer of metallic shielding fabric mounted to a layer of protective fabric formed as a displaceable layer of the garment body. The disclosed embodiments of the invention show displaceable layers in the form of foldable cuffs on sleeves, epaulets, decorative pocket-like flaps, and faux seams. Any of these displaceable layers may be retained in either "active" or "inactive" position, or both, by known retention devices, including snap fasteners, zippers, buttons, and hook-and-loop fasteners. In one embodiment, inherent tension in the structure of the garment is relied upon to maintain the shielding layer in the "active" position with the fabric antenna surface exposed, while the tension of the garment structure is overcome by a partially separable zipper device, to retain the shielding layer in its "inactive antenna" position.
    • 用于选择性地屏蔽织物天线的方法和装置将织物天线(12)结合到可穿戴服装(30)的主体(10)中,并且为穿用者的穿着者提供保护,同时允许穿戴者使服装主体(22 ,24),以便使天线(12)有效或无效。 为了保护服装的穿用者免受使用天线时可能产生的射频场的影响,金属织物屏蔽层位于天线和佩戴者身体之间的服装体内。 另一层金属屏蔽织物安装在形成服装体的可移动层的防护织物层上。 本发明所公开的实施例示出了在袖子,肩章,装饰口袋状襟翼和人造接缝上的可折叠箍带形式的可移位层。 通过已知的保持装置,包括按扣,拉链,纽扣和钩环紧固件,可以将这些可移位层中的任何一个保持在“主动”或“非主动”位置或两者中。 在一个实施例中,服装结构中的内在张力依赖于将防护层维持在“活动”位置,织物天线表面暴露,而服装结构的张力被部分可分离的拉链装置克服, 将屏蔽层保留在其“无效天线”位置。
