Microstrip patch antenna for high temperature environments
ActiveUS7283096B2Improve performanceImprove reliabilitySimultaneous aerial operationsAntenna adaptation in movable bodiesMicrostrip patch antennaSpray coating
A patch antenna for operation within a high temperature environment. The patent antenna typically includes an antenna radiating element, a housing and a microwave transmission medium, such as a high temperature microwave cable. The antenna radiating element typically comprises a metallization (or solid metal) element in contact with a dielectric element. The antenna radiating element can include a dielectric window comprising a flame spray coating or a solid dielectric material placed in front of the radiating element. The antenna element is typically inserted into a housing that mechanically captures the antenna and provides a ground plane for the antenna. Orifices or passages can be added to the housing to improve high temperature performance and may direct cooling air for cooling the antenna. The high temperature microwave cable is typically inserted into the housing and attached to the antenna radiator to support the communication of electromagnetic signals between the radiator element and a receiver or transmitter device.

Circuit board having a peripheral antenna apparatus with selectable antenna elements
ActiveUS7193562B2Simultaneous aerial operationsPrinted electric component incorporationImpedance matchingRadio frequency
A circuit board for wireless communications includes communication circuitry for modulating and / or demodulating a radio frequency (RF) signal and an antenna apparatus for transmitting and receiving the RF signal, the antenna apparatus having selectable antenna elements located near one or more peripheries of the circuit board. A first antenna element produces a first directional radiation pattern; a second antenna element produces a second directional radiation pattern offset from the first radiation pattern. The antenna elements may include one or more reflectors configured to provide gain and broaden the frequency response of the antenna element. A switching network couples one or more of the selectable elements to the communication circuitry and provides impedance matching regardless of which or how many of the antenna elements are selected. Selecting different combinations of antenna elements results in a configurable radiation pattern; alternatively, selecting several elements may result in an omnidirectional radiation pattern.

Phased array metamaterial antenna system
ActiveUS6958729B1Reduce sidelobeIncrease amplitude performanceSimultaneous aerial operationsRadiating elements structural formsSolid substratePhased array
An efficient, low-loss, low sidelobe, high dynamic range phased-array radar antenna system is disclosed that uses metamaterials, which are manmade composite materials having a negative index of refraction, to create a biconcave lens architecture (instead of the aforementioned biconvex lens) for focusing the microwaves transmitted by the antenna. Accordingly, the sidelobes of the antenna are reduced. Attenuation across microstrip transmission lines may be reduced by using low loss transmission lines that are suspended above a ground plane a predetermined distance in a way such they are not in contact with a solid substrate. By suspending the microstrip transmission lines in this manner, dielectric signal loss is reduced significantly, thus resulting in a less-attenuated signal at its destination.

The power storage device includes an antenna for receiving an electromagnetic wave, a capacitor for storing power, and a circuit for controlling store and supply of the power. When the antenna, the capacitor, and the control circuit are integrally formed and thinned, a structural body formed of ceramics or the like is partially used.
