摘要:
In accordance with embodiments of the present disclosure, an information handling system may include an enclosure for housing information handling resources of the information handling system, the enclosure having an antenna slot formed therein and formed from a material substantially different from that in which the remainder of the enclosure is formed and a circuit board mechanically coupled to the enclosure and proximate to the antenna slot, the circuit board comprising an antenna electrically coupled at two or more locations to the enclosure so as to form a loop antenna and the antenna positioned such that the antenna at least partially overlaps the antenna slot.

Provided is a single-polarized antenna. This single-polarized antenna includes a power divider and a Vivaldi oscillator array. The Vivaldi oscillator array includes multiple Vivaldi oscillator units uniformly distributed in a circumferential direction of the Vivaldi oscillator array. The power divider includes multiple output ports in one-to-one correspondence with the multiple Vivaldi oscillator units. The multiple output ports of the power divider are coupled to the multiple Vivaldi oscillator units in a one-to-one correspondence.

An electromagnetic screen (1) comprises a plurality of antennas (4) each of which reflects an electromagnetic wave having a specific frequency. The plurality of antennas (4) are arranged so as to constitute a pattern. Each of the antennas (4) has three segment-shaped first element parts (4a) and three segment-shaped second element parts (4b). The three first element parts (4a) radially extend from the center of the antenna (4) by substantially the same length such that any two of the three first element parts (4a) form an angle of 120° with each other. Each of the second element parts (4b) are connected to an outer edge of a corresponding one of the first element parts (4a).

A radio frequency identification (RFID) inlay includes an electrical connection between a chip and an antenna. The electrical connection includes conductive interposer leads and a capacitive connection. The capacitive connection may involve putting the antenna and the interposer leads into close proximity, with dielectric pads therebetween, to allow capacitive coupling between the antenna and the interposer leads. The dielectric pads may include a non-conductive adhesive and a high dielectric material, such as a titanium oxide. The connections provide a convenient, fast, and effective way to operatively couple antennas and interposers. The RFID inlay may be part of an RFID lable or RFID tag.
