Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a reflector antenna. Moreover, it is determined that it has improved electrical properties. [Prior Art] Dual-polarized microwave communication links _-the money for different polarizations, so the same single-signal/bipolar communication link can enable the link. Increased capacity. However, due to the requirements of signal separation and/or the value of each money, the electrical performance is degraded for each number. With the use of ground-based communication systems, especially in limited spectrum environment towels, the use of age-old links is increasing for filaments with a slightly increased chain amount. The conventional terrestrial communication reflector antenna used with the single signal/bipolar communication link can be placed in a compact assembly in which the transceiver is mounted next to the back of the reflective disk. Thus, the requirement for antenna return loss can be relaxed, and the insertion budget and link budget are improved. Since additional channel and functional duplication enable dual signal processing, a typical dual-polarized communication link uses a reflector antenna with a remote transceiver mount, requiring additional waveguide and/or transceiver mount requirements . The dual polarized electrical signal received by the reflector antenna is separated by 0MT inserted into the channel. The separated signals are then each transported to a dedicated transceiver. The electrical properties to be considered for a dual polarized reflector antenna element include the inter-turn isolation (ΙΡΙ) between the antenna feed and the two orthogonal polarizations on the transceiver. The IPI performance of the OMT contributes to the cross-polarization discrimination characteristics of the entire antenna element of 4 201222969. If the XPD of the dual-polarized antenna element is reduced, the cross-polarization string_XPIC will be (4), which means that the positive traffic lanes will interfere with each other and the whole copper link will be reduced. However, if the OMT/channel is physically large, depolarization becomes an additional factor because the signal energy has to increase the distance traveled between the radio 璋 and the feed 埠. The international patent application publication and the disclosure of the OMT and the interconnected waveguide element respectively can be used together in a dual polarized reflector antenna element having a transceiver mounted immediately behind the reflector. The internal signal surface of the OMT in the w〇2〇〇7/〇88i83 includes a complex boss spacer polarizer feature. Due to the OMT component divergence orthogonal material, the eyeliner (4) is cost-effectively and accurately machined. The target is OMT or anti-(four) antenna feed, coordinating the parts between different inverter antenna configurations and / or applying the optional 〇MT configuration to existing facilities 'eg in existing reflective limb components from single Facilities that are polarized to field conversion/upgrade in dual-polarized operation can be difficult. SUMMARY OF THE INVENTION A 90 degree channel variation within the OMT is required to align the OMT output on the 〇MT/feed hub transceiver side with the longitudinal axis of the reflector antenna. The interconnected waveguide element between the OMT and the input port of the transceiver in w〇2〇〇7/〇88184 must therefore have an additional 90 degree bend to be orthogonal to the longitudinal axis of the same || The configuration works with the transceiver. The variation of each additional 9-turn channel complicates manufacturing, extends the total channel' and introduces an additional opportunity for depolarization attenuation of the IPI and/or signal. The microwave operating frequency extends over a wide frequency range, usually in the S; 5 201222969. The existing solution for reflex antennas is typically only designed for narrowbands in this band, so it needs to be completely redesigned, reinforced, manufactured and The inventory of the antenna elements is not at all responsive to market demand. The competition in the reflector antenna market is aimed at improving electrical performance and minimizing total manufacturing, inventory, distribution, wire and maintenance costs. Accordingly, it is an object of the present invention to provide a dual polarized reflector antenna configuration that overcomes the deficiencies of the prior art. [Embodiment] The inventors have invented a dual polarized reflector antenna element in which a 0 ΜΤ/interconnected waveguide element mountable on the back side of a reflector/reflecting n-feed hub enables the transceiver mount to be placed next to the reflector The back side and improved electrical performance. In addition, the modular features of the ΟΜτ/waveguide components can also be easily interchanged/configured for operation at different operating frequencies and/or required electrical performance tradeoffs. In a first embodiment of the dual polarized reflector antenna element 2, as shown in Figures 1 and 2, the transceiver (optionally a separate receiver and/or transmitter) is removed for clarity, transceiving The machine bracket 4 is coupled to the back surface of the reflector disk 6 and is fixed to the feed hub 8 of the reflector antenna 10. For example, the weir/feed element 12 can be coupled at the proximal end 16 to the feed cassette 14' of the feed hub 8 and at the distal end 18 by the transceiver tray 4. Those skilled in the art will recognize that the proximal end 16 and the distal end 18 are end names that are introduced to facilitate interpretation of component orientation and/or interconnection relationships. Each of the elements also has a proximal 16 and a distal end 18, i.e., the ends of the elements face the proximal end 16 or distal end 18 of the associated element, respectively. 6 201222969 As best shown in Figure 3, the 0MT/feed component! 2 includes a circular square waveguide age 22, a square waveguide 24, a 〇MT26, and a pair of polarization adapters π which are connected in series to form a waveguide channel from the feed port 14 of the feed hub 8 to the transceiver input port. The circular-square waveguide converter 22 can be formed as a one-piece component that eliminates the gaps along the sidewalls of the channel to introduce signal attenuation. The square waveguide module 24, which is lightly coupled at the proximal end to the circular-square waveguide converter 22 and to the bore (10) at the distal end 18, has a square waveguide % extending between the proximal end 16 and the distal end 18. As best shown in Figures 4 and 5, the three side walls of the square waveguide 3 are formed in the recessed portion 32 of the square waveguide module 24, and the fourth side wall of the square waveguide 30 is formed in the branch. The pilot 24 is shouting 36. The feeding portion % and the cap portion % ^ are fitted together by a key member 38 such as a plug-in _ _ _ _ _ _ _ _ _ _ _ _ _ Since the three sides of the square waveguide 30 are formed between the groove portion 32 and the cover portion 36 along the slit of the square scale 3G, the square waveguide knife is located away from the center of the lining wall 34' during the propagation of the square waveguide signal. Lower L _. In addition, in the process of manufacturing a person skilled in the art, the high tolerance square of the square waveguide 3〇 is non-difference "the cost has a square money, and the alignment of the center of the inverted wall 读 is not a problem. . In order to allow the feed 42 of the reticle 26 (Fig. 3) to be symmetrical with the longitudinal axis of the 〇ΜΤ/feed element 12, the _final _ length of (10) τ % is minimized to 201222969. The distal end 18 of the square waveguide 30 can be laterally offset. The 〇Μτ/feed assembly 12 is streamlined and does not require a pair of 9-turn bends and a transition portion on the rectangular waveguide 3 〇 path. The longitudinal length of the square waveguide 30 is selected to set the output port 42 to the desired furnace position 3 relative to the transceiver bay 4; 1 'for alignment with the input port of the transceiver. As shown in Figures 6 and 7, the migratory 26 can be formed by two half-shadows, the two half-pieces being mated by key members such as pins and sockets and/or a plurality of fasteners such as screws. 〇ΜΤ 26 separates and converts each of the polarities of the rectangular waveguides 44 that are oriented at 90 degrees from each other, i.e., at the intersection 49 of 〇μτ, into a vertical and water-based signal. The design and dimensions of the Μ 交叉 intersection 49 are dependent on the size and operating frequency of the input and output waveguides, and thus will not be described in further detail herein, in accordance with the microwave propagation theory well known in the art. Although the gap between the two half-half sheets 46 is located at the center of the respective rectangular waveguide side walls 34, it can be present on the center side wall only by placing the small-sized portion of the square waveguide 30 in the square waveguide of the GMT 26. The channel portion of the gap is minimized. In addition, the two 0MT half-piece structures of = 26 greatly simplify the addition of X to the transition surface between the square waveguide % and each rectangular waveguide 44, such as any precision boss feature. The waveguide channel between the feed raft 14 and the feed material, as best shown in Fig. 3, includes only three 90 degree bends, each bend being located within the 〇MT26. A reduction in the number of 9 turns can shorten the total channel length and improve electrical performance. The polarization adapter 28 can be lightly coupled to each of the output ports 42 to direct the respective channels to the input of each of the 201222969 transceivers. Each practice is oriented to maintain the preferred/required orientation of any heat sink, service and/or environmental seal of the transceiver at a location mirrored to the other transceiver. In the 13Ghz band evaluation, the dual polarized reflector antenna element 2 according to the first embodiment has a significant improvement in m compared to conventional remotely mounted transceiver devices. In a second embodiment of the dual polarized reflection & antenna element 2, as shown in Figures S and 9, the transceiver (optionally a separate receiver and/or transmitter) may be removed for clarity, The transceiver carrier 4 is coupled to the back side of the reflector disk 6 and is fixed to the feed hub 8 of the reflector antenna 10. The OMT/feed assembly 12 is coupled at the proximal end 16 to the feed cassette 14 of the feed hub 8 and at the distal end 18 by the transceiver carriage 4. As best seen in Figure 10, the 'OMT/feed assembly 12 includes a circular-square waveguide converter 22, an OMT 26, and a polarization adapter 28 that are coupled in series to form a feed port 14 from the feed hub 8 to the transceiver. The input channel of the machine. As shown in Figures 11 and 12, the OMT 26 can be formed from two OMT half sheets 46 that are also mated together by key members 38 such as pins and sockets and/or a plurality of fasteners 40 such as screws or the like. The OMT 26 separates and converts each polarity of the rectangular waveguide 44 that is oriented 90 degrees from each other from the square waveguide input 埠 48, i.e., to the vertical and level polarization signals at the intersection 49 of the OMT.

The two clear halves of the 26 structure greatly simplify the processing of the transition surface between the square waveguide % and each rectangular waveguide 44, for example eliminating any precision boss features. As best shown in Figure 1A, the passage between the feed 14 and the output weir includes only five 90 degree f-curves, each bend being located within 〇Μτ %. The reduction in the number of 9-turn bends can depend on the total channel length and improve electrical performance. Polarization adapter 28 (Fig. 10) can be tapped with each output port 42 to align the respective channels with the input of each transceiver. From the riding chain, the machine can be oriented in the same way as the other - transceivers, such as the inspection, to ensure that the heat dissipation, drainage and/or environmental sealing is preferred/required orientation. Those skilled in the art will appreciate that as the word increases, high performance dual mode waveguide signal propagation is more dependent on the high dimensional tolerance characteristics of the waveguide. Therefore, the second embodiment rides as close as possible to the feed correction setting 〇MT to minimize the length of the square waveguide, instead of using the unipolar rectangular waveguide 44 to obtain the requirement to offset the channel of the transceiver mounted near the back of the reflective disk 6. In a third embodiment of the dual polarized reflector antenna element 2, as shown in Figures 13 and 14, the transceiver (optionally a separate receiver and/or transmitter) may be removed for clarity, The transceiver carrier 4 is coupled to the back side of the reflector disk 6 and is fixed to the feed hub 8 of the reflector antenna 10. The cassette/feed assembly 12 is coupled at the proximal end 16 to the feed cassette 14 of the feed hub 8 and at the distal end 18 by the transceiver tray 4. As best shown in Figure 15, the ΟΜΤ/feed assembly 12 includes a feed 埠 adapter 5 〇, a circular waveguide 52, a circular-square waveguide converter 22, a ΟΜΤ 26 and a polarization adapter 28, 201222969 which are coupled in series to form From the feed port 14 of the feed hub 8 to the channel 0 of the transceiver input port, as shown in Figures 16 and 17, the OMT 26 can be formed from two OMT half sheets 46 that also pass through key members 38 such as pins and sockets. And/or a plurality of fasteners 40 such as screws or the like are fitted together. The 〇 MT 26 separates and converts each polarity of the rectangular waveguide 44 that is oriented 90 degrees from each other from the square waveguide input 埠 48, i.e., to the vertical and level polarization signals at the intersection 49 of the OMT. According to the microwave propagation theory well known in the art, the design and size of the OMT intersection 49 depends on the size and operation of the input and output waveguides, and will not be described in detail herein. The longitudinal length of the circular waveguide 52 is selected to position the output port 42 at a desired coupling position 31 relative to the transceiver carrier 4 for alignment with the input port of the transceiver. Therefore, the length of the rectangular waveguide 44 can be significantly shortened. The two OMT half-piece structures of the OMT 26 greatly gravate the processing of the square waveguide 3〇 and the surface of each gamma waveguide, for example, eliminating any precision boss features. As best shown in Figure 15, the passage between the feed weir 14 and the output weir includes only a 9 degree bend, each bend being located within (10) T26. The number of bends in the 9th turn (4) reduces the total length of the channel and improves the electrical performance. " Polarization Adapter 28 (Fig. 15) can be aligned with each output 埠42_ to input the input 每个 of each transceiver of the respective channel. Thus each transceiver can be oriented at the same time as the mirror, any heat sink, service and preferred/required orientation of the tilting machine. Brother~ The technicians in the field can understand that as the frequency increases, the dual-mode waveguide signal propagation in the circular waveguide 2 in the middle of 201222969 becomes more dependent on the ellipticity of the circular waveguide. Since the cylindrical circular waveguide 52 extends from the sub-reflector (not shown) through the feeding hub 8 to the circular-square waveguide converter 22, there is no dimensional change or longitudinal sidewall slit, and therefore, in terms of ellipticity, the extended circle The high tolerance of the waveguide channel can be cost effectively maintained. Moreover, because the unipolar rectangular waveguide 44 portion of the OMT 26 is minimized by the OMT 26 tight receiver setting, the number of 90 degree bends in the OMT 26 and the overall length of the interconnected rectangular waveguide 44 are minimized. Using a common reflector disk 6, feed hub 8 and transceiver carrier 4, the embodiments of each OMT/feed element 12 can be interchanged with one another, thus providing easy operation for optimal operation over a wide frequency range of typical microwave frequencies. Configuration without having to separately design, manufacture, and stock multiple frequency-specific reflector antenna configurations. Furthermore, the existing unipolar antenna element arrangement can be simply upgraded in situ to a dual polarization configuration, since the feed hub 8 and associated sub-reflector/feed elements need not be disturbed, including sub-reflectors/feeds, feeds Alignment and/or sealing between the hub 8 and/or the reflective disk 6.
