ANTENNA DESIGNS AND SYSTEM FOR REDUCING ENERGY EMISSIONS FROM WEARABLE MOBILE DEVICE

摘要

The present invention relates to design of antennas for efficient communication over the radio-frequency airwaves in applications such as cellular phones and more particularly, wearable wireless devices, and to a system for reducing the overall electromagnetic energy radiated from a cellular phone designed to be worn on the body. The invention includes a series of antenna designs with a configuration of materials that can transmit wireless signals efficiently without excess power being emitted, enabling regulatory approval of a wearable wireless communications device, enhancing consumer safety, and increasing battery life. The design further enables a single antenna, with extraordinarily small physical dimensions, to be used across many of the most popular wireless communication spectra in the United State and worldwide. The accompanying system further reduces the electromagnetic emissions from a cellular or mobile communications device designed to be worn on the body, further enabling such devices to meet relevant regulatory approval standards in the United States and elsewhere.

主权项

1. A radio frequency (RF) antenna, comprising:
a flexible substrate layer or layers made of one of the many materials typically used for flexible printed circuit manufacture; a flexible conductive layer or layers made of one of the many materials typically used for flexible printed circuit manufacture; a series of negative traces (areas where the conductive layer or layers has been removed from or not applied to the substrate layer or layers) in the conductive layer or layers, forming antenna arms, arranged in a pattern that includes a first horizontal arm, one end of which first horizontal arm intersects with one end of a vertical arm, so that the vertical arm is positioned at an angle of less than 90 degrees but more than 45 degrees relative to the first horizontal arm, and also includes a second horizontal arm intersecting the vertical arm, the second horizontal arm running parallel to the first horizontal arm for a distance until the second arm is angled away from the first horizontal arm at an angle between 5 degrees and 35 degrees
