    Abstract: The use of rectennas, or antenna-coupled rectifiers, using metal-insulator-metal tunnel diodes as rectifiers for energy conversion has been explored with more fervor recently, given the advances in nanotechnology fabrication and increased resolution of features. Some have made these devices from symmetric metals (e.g. Ni—NiO—Ni) and asymmetric metals (e.g. Al—AlOx/Pt), and have used deposited oxides as well as native oxides. One key to obtaining a highly asymmetric device with efficient current generation needed for high conversion efficiency is to instead use dissimilar metals and a thin reproducible oxide. The described method allows for a thin, reproducible native oxide of nickel be integrated with any antenna metal to overcome oxide surface roughness problems that typically hamper the practicality of these devices.

    Abstract: A mobile multiband antenna has a frequency matching circuit located in a base mount housing for mounting the antenna to a carrier. A heat sink is located on a reverse side of the frequency matching circuit. One or more resistors in the frequency matching circuit are mounted to the heat sink to dissipate heat.

    Abstract: A dipole antenna comprises a hollow dielectric whip, a coaxial center feed extending therethrough, and a pair of conductive dipole elements comprising an upper element and a lower element. The dipole antenna further comprises an upper element lead connecting the upper element to a first portion of the coaxial center feed at a feed point and a lower element lead connecting the lower element to a second portion of the coaxial center feed at the feed point. The dipole antenna further comprises a feed point strengthening means to mechanically strengthen the feed point against disconnection when the whip is impacted. Additionally, the dipole antenna may be a dual dipole antenna.

    Abstract: Nuclear quadrupole resonance substance detection at a distance is provided by crossed or overlapping high frequency beams in which the frequency of one of the beams is offset with respect to the frequency of the other beam by an amount equal to the resonant frequency of the non-linear material to be detected. The presence of energy at the offset frequency within the overlapping beams pumps any non-linear material within the overlapping beams to cause stimulated emission which is detected, in one embodiment, utilizing a network analyzer, along with correlation of the detected stimulated emission signature with a library of signatures for predetermined substances.

    Abstract: A television antenna is constructed of a flat plate antenna comprising a plurality of concentric, rectangularly shaped loops formed of conductive material and disposed on a substrate. Each loop forms an antenna for signals in a predefined frequency band within the TV frequency spectrum. An additional loop is disposed within the plurality of concentric loops and is adapted for receiving signals in the FM frequency range. Each of the loops has four sides having an electrical length equivalent to one-quarter wavelength at a center frequency within a frequency band and each side of each antenna loop is connected to a side of another antenna loop and to one of a pair of antenna output terminals. The sides of each loop are formed by conductive strips deposited on a dielectric substrate which is particularly adapted for installation adjacent a dielectric roof panel or the like.
