    摘要: A wideband antenna system with multiple antennas and at least one parasitic element is disclosed. In an exemplary design, an apparatus includes a first antenna, a second antenna, and a parasitic element. The first antenna has a shape of an open-ended loop with two ends that overlap and are separated by a gap. The second antenna may also have a shape of an open-ended loop with two ends that overlap and are separated by a gap. The parasitic element is located between the first and second antennas. The first and second antennas may be placed side by side on a board, located at either the top end or the bottom end of a wireless device, and/or formed on opposite sides (e.g., the front and back sides) of the board. The parasitic element may be formed on a plane that is perpendicular to the plane on which the first and second antennas are formed.

    摘要: Reconfigurable intelligent surfaces (RISs) are an emerging transmission technology to aid wireless communication. However, the potential of using RIS to mitigate directed energy weapons (DEW) is not widely recognized. Described herein are RIS (based on spiral antenna elements) to aid the mitigation of high-energy radio-frequency (RF) sources applied to a DEW. For example, integrating a broadband circularly-polarized antenna system with RIS technology can successfully mitigate DEW attacks across a wide range of frequencies regardless of how radio waves are polarized. A spiral antenna is simulated that operates between 1.3 GHz and 7 GHz with a 3-dB axial ratio bandwidth (ARBW) covering 2 GHz-7 GHz. Full-wave simulation results show the potential promising application of RIS for the mitigation of DEW attacks.

The radiator includes a feed-in part, a first radiation part straightly extended rightward from an upper section of a first right edge of the feed-in part, and a second radiation part sequentially extended rightward, then extended upward, later extended leftward, and further extended downward from a lower section of the first right edge of the feed-in part. The grounding body is arranged on a lower portion of the circuit board. The grounding body is positioned adjacent to a lower portion of a second right edge of the radiator. The grounding body is separated from the radiator.
