Abstract: Antennas for electronic devices such as portable computers are provided. An antenna may be formed from a conductive cavity and an antenna probe that serves as an antenna feed. The conductive cavity may have the shape of a quartered rectangular cavity and may have first and second side walls, top and bottom walls, and first and second openings. The first and second openings may be planar in shape and may meet at a right angle along an axis. The antenna probe may be disposed along the axis. The axis at which the first and second openings of the cavity meet may be located at the corner of an electronic device housing. The portable computer may have upper and lower housing portions that meet at a gasket. The gasket may be placed adjacent to the cavity face openings so that radio-frequency signals may enter and exit the cavity through the gasket.

Abstract: A microwave antenna and light tracking system includes a microwave antenna, a microwave source, a light sensor, and a beam-guide system. The beam-guide system has a mirror set with at least one guide microwave mirror operable to guide a microwave beam along a first portion of a microwave path toward the antenna. Each microwave mirror has embedded therein a light mirror positioned to direct a light beam along a first portion of a light path substantially coincident with the first portion of the microwave path but in a reverse direction from the antenna. The beam-guide system further includes a dichroic beam splitter including a dichroic beam splitter microwave mirror having a light-transparent window therethrough. The dichroic beam splitter is disposed in a second portion of the microwave path between the mirror set and the microwave transmit/receive device and in a second portion of the light path between the mirror set and the light sensor. The microwave source is positioned to direct a microwave signal to the dichroic beam splitter, whereupon the microwave signal is reflected along the second portion of the microwave path to the mirror set and thence to the antenna. The light sensor is positioned to receive light transmitted along the second portion of the light path through the light-transparent window of the dichroic beam splitter.

Abstract: The teachings of the present application generally for an ultra-high frequency (UHF) antenna assembly which provides for a smaller package size with the same or better efficiency as a much larger antenna, particularly between 100 MHz to 500 MHZ. Particularly, through the combination of components and structures for implementing frequency selective surfaces (FSS) and high impedance structures (HIS) in combination with an anisotropic magneto-dielectric material, the present teachings provide for the use of both lower and higher frequency techniques through the operational frequency band and miniaturization, accurately improving the performance of UHF satellite communication antennas. Specifically improving performance in narrowband, with increases in efficiency, bandwidth, and lowered elevation angle radiation characteristics.

Abstract: Provided is a frequency selective surface including a conductor plane (101), nine loop slots (102) each formed to be surrounded by the conductor plane (101), and a capacitance component (103) disposed to straddle the loop slots (102) in a width direction, both ends of the capacitance component being connected to the conductor plane (101) at a position near the loop slots (102). The conductor plane (101) and the loop slots (102) each formed to be surrounded by the conductor plane (101) constitute a unit cell (110). The unit cells (110) are two-dimensionally periodically arranged. One or more (four in the case of FIG. 1) capacitance components (103) disposed to straddle the loop slots (102) in the width direction are provided for each loop slot (102). Operating frequencies can be easily changed by adjusting only a component connected to the unit cell, or a part of metallic patterns.
