Abstract:
Low-profile, compact embedded multi-mode antenna designs are provided for use with computing devices, such as laptop computers, which enable ease of integration within computing devices with limited space, while providing suitable antenna characteristics (e.g., impedance matching and radiation efficiency) over an operating bandwidth of about.8 GHz to about 11 GHz.
Abstract:
PROBLEM TO BE SOLVED: To provide a display, a computer terminal and an antenna which enables an antenna to be installed without enlarging its frame or downsizing a display panel, and can receive radio waves sufficiently well, if the frame is made of a conductive material. SOLUTION: A notebook type computer terminal has a thin sheet-like slot antenna 20, installed in a gap between a display panel 13 and a sidewall 16 of a display panel frame 14, with its a transmitter-receiver 20a being projected over a prescribed length from a conductive material-made casing 13A of the display panel 13 and a stay 21. The antenna 20 has a ground part 20b connected to the ground of a radio wave-signal converter circuit and also to the conductive material-made frame 14 via the stay 21.
Abstract:
Apparatus and methods are provided for integrally packaging semiconductor IC (integrated circuit) chips and antenna devices which are integrally constructed from package frame structures (e.g., lead frame, package carrier, package core, etc.), to thereby form compact integrated radio/wireless communications systems for millimeter wave applications. For example, an electronic apparatus (30) includes a package frame (11) having an antenna (12) that is integrally formed as part of the package frame (11), an IC (integrated circuit) chip (13) mounted to the package frame (11), interconnects (19) that provide electrical connections to the IC chip (13) and the antenna (12), and a package cover (15).
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna which is constituted by using one or a plurality of conductive via stubs formed as radiating elements in a substrate. SOLUTION: A method which constitutes the antenna contains a step for preparing the substrate having a first and a second surfaces which are almost parallel to each other, and a step wherein via holes are formed between the first and the second surfaces penetrating the substrate and filled with a conductive material, the conductive via stubs are formed and the radiating elements are formed in the substrate. The antenna and an IC chip (e.g. a transceiver of an IC type, a receiver, a transmitter, etc.) are collectively packaged, and an integrally formed communication system for radio or RF (high frequency) can be formed.
