摘要： A base station antenna includes a panel that has a ground plane, first and second arrays that have respective first and second sets of linearly arranged radiating elements mounted on the panel, and a decoupling unit positioned between a first radiating element of the first array and a first radiating element of the second array. The decoupling unit includes at least a first sidewall that faces the first radiating element of the first array, a second sidewall that faces the first radiating element of the second array and an internal cavity that is defined in the region between the sidewalls. The first and second sidewalls are electrically conductive and electrically connected to the ground plane.

摘要： A volumetrically compact and efficient antenna, with a high radiation resistance and low losses, that can be designed for any frequency, and which has a gain within 1 dB of that of a full-sized vertical monopole radiator or, in its horizontally polarized form, within 2 dB of that of a horizontally polarized half-wave dipole. One embodiment is a rectangle, with short radiators and long interconnecting wires, which has been folded back on itself in a manner that results in a square configuration (when viewed from the top) and brings the two radiating wires into close proximity. Only a single port need be fed. Linear loading sections, such as stubs, serrations and helically wound interconnecting wires can be used to electrically lengthen the antenna, while keeping physical dimensions small. Capacitive loading sections are also used. Two unequal-sized rectangular loops may be joined onto each other, to provide an additional radiating element.

摘要： Polarization current antennas include an arc-shaped dielectric radiator, electrodes, and a feed network. The electrodes and feed network are configured to generate an electric field within the dielectric radiator. The electrodes are positioned on the top and bottom of the dielectric radiator and the electromagnetic radiation is emitted through the outer surface thereof. Phase differences between excitation signals supplied to the electrodes may be selected so that a speed of a volume polarization distribution current pattern that is generated in the dielectric radiator will be substantially equal to the speed of light within the dielectric radiator. The antenna emits both conventional spherically decaying electromagnetic radiation and as non-spherically decaying electromagnetic radiation that decays as a function of distance d at a rate that is less than 1/d2. The non-spherically decaying radiation includes a highly focused beam that has an angular beamwidth that narrows as the distance d increases.

摘要： An endfire antenna structure is disclosed that is for use on aerodynamic systems. The antenna structure includes a first layer of patterned metal, a second layer of patterned metal, and a stack of material layers that includes the first layer of patterned metal and the second layer of patterned metal. The first layer of patterned metal includes a plurality of parallel slots etched through the metal. The second layer of patterned metal includes a tapered radio frequency (RF) feedline having a narrow end coupled to an input/output (I/O) antenna connection. The second layer of patterned metal is aligned over the first layer of patterned metal such that the tapered RF feedline has a length that extends across the plurality of parallel slots. The stack of material layers is flexible such that the stack of material layers is configured to wrap at least partially around the fuselage of an aerodynamic system.

摘要： This invention relates to dynamically controlled, electronic article surveillance (EAS) systems whereby an array of antenna elements is digitally phased and actively driven for concurrent transmission, and digitally phased and combined in the receiver unit to improve security tag detection. In particular, the individual frequency and phase of the plurality of the transmit/receive signals are rapidly varied to allow for automated manipulation (steering) of the transmit field pattern and receive field sensitivity. It is the object of this invention to achieve the following features via means of digital phasing and dynamic computer control: sufficient far-field cancellation, null-free detection and uncompromised detection performance regardless of tag's orientation.
