Definitions
- the invention is based on a multibeam phase array antenna device with radiator elements arranged in a matrix, each of which can be controlled via beam shaping devices are.
- EP 0 651 461 B1 is a phase carry receiving antenna known, arranged in the radiator elements in rows and columns are.
- the reception signals of the radiator elements are summarized in rows and columns using signal combiners and then a non-linear logic circuit fed to a desired preferred direction of this receiving antenna to obtain.
- EP 0 368 121 B1 shows an antenna device for the Reception with radiator elements arranged in a matrix, each radiator element having an amplifier and a filter device having. Those received on the radiator elements Signals are grouped using signal dividers divided and each to a beam shaping device guided. The output signals are via signal combiners the beam shaping devices to form several antenna signals summarized.
- the measures of the main claim and the configurations according to the subclaims can be a very compact Structure of the antenna device achieve that flexibly the number of feedable antenna signals for transmission or removable antenna signals for reception and be adapted to the number of radiator elements can.
- By accommodating the jet shaping devices in a defined line behind a radiator element is the area requirement of the jet shaping devices in the Profile (cross section) identical to the area of the radiator elements.
- the depth of a strand depends on the Complexity of the overall system, that means especially the antenna signals to be fed or taken, and is variably adjustable.
- Another advantage is the combination of several strands each in a tub-like module.
- beam shaping devices is in particular only one circuit carrier substrate necessary, the back of it beyond still for accommodating signal dividing devices can be used so that no additional space is required arises.
- the antenna device according to the invention is distinguished due to a high integration density and compactness out.
- the antenna device according to the invention can be advantageous use as a microwave antenna in the Ku / Ka band, what but does not exclude the use in other frequency ranges.
- Figure 1 shows a schematic overview of the signal paths within the multibeam phase array antenna. Below is described the antenna for use as a transmitting antenna. The signal curves are for use as a receiving antenna to look in the opposite direction.
- n feedable antenna signals - so-called beams - which are each led to a signal dividing device V1 to Vn.
- These signal dividing devices V1 to Vn are combined in block V and divide the power of the beams into m-part signals in each case, in order to control one line of n-beam shaping devices.
- the respective m outputs of the signal distribution device V1 to Vn are routed to a beam shaping device BFN via a connection multiple KF.
- a total of m ⁇ n beam-shaping devices BFN are accordingly provided, which generally consist of active amplitude adjusters A and phase adjusters P and possibly an intermediate amplifier (not shown). This repeater can also be used as amplitude adjuster A at the same time.
- the control elements are usually designed as MMIC circuits (Monolithic Microwave Integrated Circuit). Several phase adjusters and / or amplitude adjusters can be accommodated in one MMIC, for example.
- each Radiator element SE1 ... SEm from each of the n feedable antenna signals (Beams) can be fed.
- Figure 2 shows the cross-sectional area of the beamform networks BFN the size of the radiation elements in the front surface adapted to the antenna.
- the depth of a strand of beamform networks BFN is variable and the number of each n BFN beam shaping devices dependent.
- Behind everyone Steel element SE1 ... SEm become the front surface in one vertical strand (channel) the active blocks A and P for beam shaping and amplification VS1 ... VSm as well as filter devices FI1 ... FIm housed.
- the number of strands (channels) is identical to the number m of radiator elements SE1 ... SEm.
- the number of active beam shape components per line (channel) is identical to the number n of antenna signals (beams). In total there m.times.n active beam shape components necessary.
- the strands of beam shaping devices, which lie in one plane (row) are mechanically combined in each case in a trough-like module WM, which through mechanical intermediate walls ZW brings about both mechanical separation, electrical separation (screen wall function) and heat dissipation.
- the strands (channels) are also mechanically and electrically protected by the outer walls AW.
- the reinforcement and Filter devices VS1 ... VSm or FI1 ... FIm in the trough-like Modules WM housed.
- the electrical and mechanical Separation and also the heat decoupling from the Beam shaping devices BFN is carried out by the others Screen walls SW.
- FIG. 3 shows, the trough-like stacked one on top of the other Module WM a symmetrical stable Antenna block that is shielded on all sides.
- the tub-like Modules WM take circuit carrier substrates SU according to Figure 2, the back of at least part of the n signal sharing devices / power sharing networks V1 ... V4 wear. In Figure 2 and Figure 4, these are designated VR1 ... VR4.
- the tops of the circuit carrier substrates SU carry the line structures for the active beam shaping devices BFN.
- the circuit carrier substrates SU are opposite the tub bottoms of the WM tub-like modules with spacers fixed.
- the signal routing orthogonal to the strand direction of the line structures on the back of the Circuit carrier substrates SU is very essential for that compact structure of the antenna device, since the implementation of the connection multiple KF shown in Figure 1 simple in the form of signal bushings DK ( Figure 4) in the Circuit carrier substrates SU between the line structures for the beam shaping devices BFN on the one hand and the Line structures for the signal dividing devices VR1 ... VR4 on the other hand can be realized.
- the exemplary embodiment according to FIG. 2 in FIG Signal dividing devices VR1 ... VR4 for m 16 lines designed.
- a possible realization of the signal dividing devices VR1 to VR4 is the cascading of seven 3 dB power dividers in stripline technology, e.g. cascaded Wilkinson divider as shown in Figure 2.
- the 4x8 inputs of the eight stacked tub-like Modules WM are shown on a lateral as Figure 3 shows Side of the block of the antenna device on the connectors E1 ... E32 and four other 1-to-8 power sharing networks VT1 ... VT4, which are also a component of the signal dividing devices V1 to 1 shown in FIG V4 are connected to the four beam inputs B1 to B4.
- Figure 3 shows the antenna device for eight stacked WM modules and four beams.
- the execution and dimensions of the power sharing networks VT1 ... VT4 can preferably be identical to the signal dividing devices VR1 ... VRn on the back of the circuit substrate SU.
- the strands of the beam shaping devices are BFN shown in longitudinal section.
- m 16 strands per tub-like module WM provided.
- the Outputs of the active components of the beam shaping devices BFN are each via one of the m signal combiners SK, that means summarized in each case over a power adding network.
- n 4 output signals per line (channel) summarized.
- a possible realization are here too cascaded 3-dB Wilkinson divider / combiner SK1 ... SKn.
- the clever arrangement of the active components of the Beam shaping devices and the power adding networks can the strand (channel) and thus the space required for keep the beam shaping devices BFN small.
- the principle arrangement shows Figure 5.
