Abstract: The present invention relates to a stripline arrangement (10?) comprising a number of stripline layers each comprising a laminate layer (1A, 1B) and conducting layers (2A, 2B, 3A, 3B) provided on each of said laminate layers (1A, 1B), said conducting layers (2A, 2B, 3A, 3B) each comprising a conductive pattern, RF signal (microwave) input and output ports respectively, and an interconnecting arrangement (5) for interconnecting said layers. At least two of said stripline layers are arranged such that a given overlapping zone (L?) is provided between each other facing conducting layers (2A, 2B) of said striplines layers, said interconnecting arrangement (5) comprising a bonding arrangement provided between adjacent and one another facing and overlapping conducting layers (2A, 2B).

Abstract: The invention discloses a radar system (100) for the detection of low RCS-objects (110, 140, 150, 160, 190) such as forest fires, said system comprising a first plurality of stations (120) for transmitting radar energy, said stations having mechanically fixed antennas (220), and a second plurality of receive stations (130) for receiving reflections of radar energy transmitted from the transmit stations, said stations having mechanically fixed antennas (220). The antennas (220) of said transmit and receive stations have a main beam (221) which is essentially parallel to the ground, and at least a sub-set of the receive stations is equipped with means for recording a first and a second received signal, and means for subtracting one of said signals from the other of said signals. Said transmit and receive stations are arranged to function within the frequency range of 10-100 MHz.

Abstract: The invention relates to a microwave transmission arrangement (10) comprising a carrier substrate (1), with a microstrip transmission line, on a first side of the carrier substrate (1), said carrier substrate (1) comprising at least one opening (2; 2?) forming a waveguide input/output opening to a waveguide arrangement.

Abstract: The present invention relates generally to an apparatus for interconnecting coaxial connectors with stripline circuits. A general coaxial connector housing is by glue fixed adjacent to the stripline circuit and at least one conductive element is placed in between the connector housing and the stripline ground planes.
