    摘要: Disclosed are various systems and methods for remote surface sensing using guided surface wave modes on lossy media. One system, among others, includes a guided surface waveguide probe configured to launch a guided surface wave along a surface of a lossy conducting medium, and a receiver configured to receive backscatter reflected by a remotely located object illuminated by the guided surface wave. One method, among others, includes launching a guided surface wave along a surface of a lossy conducting medium by exciting a charge terminal of a guided surface waveguide probe, and receiving backscatter reflected by a remotely located object illuminated by the guided surface wave.

    摘要: A multi-band antenna including a ground portion, a first radiation portion, a second radiation portion, a feeding portion and a matching portion is provided. The first radiation portion is disposed beside the ground portion, a first gap is existed between the ground portion and the first radiation portion so as to form a first slot, and the first slot has a first open terminal located at the first gap. The second radiation portion is connected to the first radiation portion. The feeding portion is located between the first radiation portion and the second radiation portion. The matching portion is located in the first slot and connected to the first radiation portion and the ground portion. The feeding portion excites the first slot to generate a first resonant mode. The second radiation portion generates a second resonant mode.

    摘要: Reconfigurable antenna systems with ground tuning pads are provided herein. In certain configurations, an antenna system includes a module substrate including a ground plane and a ground tuning pad configured to receive a ground voltage from the ground plane. The antenna system further includes an antenna element and a tuning conductor that is spaced apart from the antenna element and operable to load the antenna element. Furthermore, a switch is electrically connected between the tuning conductor and the ground tuning pad, and operates to selectively connect the tuning conductor to the ground plane by way of the ground tuning pad to provide tuning to the antenna element.

    摘要: An antenna device is designed to be connected to a printed-circuit board having a feeding part and a board ground. The antenna device includes a feed antenna, an antenna ground having a plate shape, an artificial magnetic conductor having a plate shape and being formed between the feed antenna and the antenna ground, a first connection connecting the feed antenna with the feeding part by passing through the antenna ground and the artificial magnetic conductor, and a second connection connecting the antenna ground with the board ground. The artificial magnetic conductor is not connected to the first connection and the second connection.

    摘要: A pattern antenna, with excellent broadband antenna characteristics, that is formed in a small area is provided. The pattern antenna includes a substrate, a first ground portion formed on a first surface of the substrate, an antenna element portion, a protruding and short-circuiting portion, and a second ground portion. The antenna element portion includes a conductor pattern in which a plurality of bent portions are formed. The conductor pattern is formed on the first surface of the substrate and is electrically connected to the first ground portion. The protruding and short-circuiting portion includes a taper portion with a tapered shape, a protruding portion, and an extended portion extended toward a side opposite to a feed point as viewed in planar view. The second ground portion, with no contact with the taper portion, with such a shape that sandwiches at least a part of a tapered section of the taper portion as viewed in planar view.
