Embodiment Construction

[0021] An antenna according to the invention comprises, for example, according to figure 1 A conductive motherboard formed by a conventional board 1 (carrier) with a metal layer 11 and a protective ceramic substrate 2 with a plurality of resonant printed wiring structures 3, 4, 5 and lead-ins 6. The metal layer 11 on the surface of the uppermost board 1 shown preferably covers the entire surface, leaving openings only where the printed wiring 12 is placed to feed the lead-in 6 . The substrate 2 is mounted on the board 1 or metal layer 11 by, for example, spot welding (not shown). The substrate 2 is shown in a transparent manner to clearly show the layout of the conductor strips.

[0022] The ceramic substrate 2 basically has the shape of an upright cube with first to fourth side faces 21 , 22 , 23 , 24 in a perpendicular relationship to the plane of the board 1 , and a top face 25 and a bottom face 26 . However, instead of such a cuboid-shaped substrate, other geometries can...

Abstract

The antenna has a ceramic substrate with at least one resonant conducting track structure and an electrically conducting base plate (1,11) on which the substrate (2) is arranged, whereby the conducting track structure (3-5) extends to the base plate at one end. The substrate is essentially square and the conducting track structure has a track on the upper side connected to the base plate via a second track along the side of the substrate. <??>AN Independent claim is also included for the following: <??>(1) a printed circuit board, especially for a mobile telecommunications device for the high frequency and microwave ranges; and <??>(2) a telecommunications device for the high frequency and microwave ranges.

Description

technical field [0001] The present invention relates to miniaturized directional antennas of ceramic substrates having at least one resonant printed wiring structure, more particularly for use in the high frequency and microwave ranges. The invention also relates to a surface-mounted (SMD—Surface Mount Device) printed circuit board (PCB) of the electrical and / or electronic components of such an antenna. Background technique [0002] Radio networks are steadily growing in importance in modern telecommunications and, more broadly, in entertainment electronics. High-frequency electromagnetic waves and the microwave range are used for the transmission of information. Examples are mobile radio bands in Europe between approximately 880MHz and 960MHz (GSM 900), between approximately 1710MHz and 1880MHz (DCS 1800), between approximately 1850MHz and 1990MHz (PCS 1900), GPS transmitting in the frequency band approximately 1573MHz Navigation signals and the Bluetooth band for data ex...
