For example, between the horizontal polarization antenna feed lines 200b and the vertical polarization antenna feed lines 200a. The conductor trace width and substrate height can be determined by laminating several pairs of layers while providing a minimum feed line loss.

The structure and feed lines of the dual-type devices can be achieved by stacking arrangement so that the dual-polarized array, according to various embodiments, can include antenna elements assigned at a high density.

Figures 8 and 9 illustrate some stacked structures of the dual-type antenna elements 200 of Figure 3, in accordance with various embodiments.

According to one embodiment, the conductive layers may be electrically connected to any one of a plurality of signal lines and a plurality of ground lines 200c. The conductive vias 200e, which electrically connect the conductive layers to one another, may include conductive vias capable of conducting all layers together and conductive vias conducting between adjacent layers.

In accordance with various embodiments, some of the conductive layers 300a for the underlying RFIC data and feed lines for power lines may include a contact layer 200d. The feed lines from the contact layer 200d may be electrically transmitted to the respective signal layers through the conductive vias 200c described above. For example, the signal layers may form strip lines (first feed port 213) feeding the first antenna 211 of the aperture radiation type structure 210 of the horn antenna shape. As another example, the signal layers may form a slot-coupler stripline (second feed port 233) that feeds the second antenna 231 of the progressive wave radiating structure 230. The mutual isolation of the adjacent signal layers can be made by the ground layer 200c.

10 and 11 illustrate exemplary layouts of an antenna array module 20 including an RFIC 300, in accordance with various embodiments.

As shown in Figs. 10A and 10B, a millimeter-wave monolithic integrated antenna module 20 may be disposed in the vicinity of the edge of the electronic device 10. For example, the structure of the antenna element 200 (the aperture radiation type structure 210 and the traveling wave radiation type structure 230) extended in the radial direction of the sector in the vicinity of the upper left side can be identified.

According to various embodiments, the antenna element 200 (s) of the antenna module 20 may be comprised of waveguide (s) disposed on at least one side of the circuit board 104. Alternatively, if the circuit board 104 is a multilayer circuit board, it may be a grid layer formed of a part of a waveguide formed on at least one layer of the circuit board 104, or a combination of conductive patterns and / or via holes formed in the multilayer circuit board . ≪ / RTI >

According to various embodiments, the antenna module 20 may include a plurality of slots forming a progressive wave radiation type structure 230 as viewed from above. A traveling radiation structure 230 may be provided by slot lines provided in the longitudinal face of the waveguide shaped aperture structure 210.

As shown in FIG. 10C, the RFIC 300 may be disposed inside the center of the antenna module 20. The RFIC 300 may be disposed adjacent to and electrically connected to the antenna elements 200, and the area occupied by the RFIC 300 and the antenna array may be 2.4? X 3 ?.

As shown in FIGS. 11A and 11B, the strip lines for electrically connecting the millimeter-wave monolithic integrated antenna module 20 may be arranged in an organic manner.

The first feed ports 211 in the form of feed strip lines and the second feed ports 233 in the form of the slot-coupler stripline form the horn antenna shape (s) from the outputs 310 of the RFIC 300, The first antenna 211 of the first antenna 211 and the second antenna 231 of the tapered slot shape (see FIG. 10).

These structures can all be fabricated in a millimeter-wave monolithic integrated antenna module 20.

According to various embodiments, the RFIC 310 and strip lines may be disposed at a distance proximate to each other. For example, feed line loss at the slot-coupler stripline needs to be minimized during feeding of the second antenna 231 from the output 310 of the RFIC 310. [ Also, for example, it is necessary to minimize the feed line loss in the strip line when feeding from the output 310 of the RFIC 310 to the first antenna 211. Thus, in order to reduce the loss of the feed lines, the RFIC 310 may be positioned to be at a minimum distance from the first antenna 211 and / or the second antenna 231 (FIG. 6C).

According to various embodiments, each structure according to the millimeter-wave monolithic integrated antenna module 20 can provide maximum full radiated power with minimized power loss at feed lines and junctions. have. All components of the millimeter-wave monolithic integrated antenna module 20 are fabricated in a general monolithic module process sequence. Thus, manufacturing tolerances and production yields can be maximized.

12 illustrates an exemplary graph of isolation and impedance matching of the radiation-type structures of the antenna array module 20, according to various embodiments.

As shown in FIG. 12A, the relationship between adjacent two adjacent coplanar elements 601 is shown through the two lines shown at the top, The relationship of the coupling between adjacent crosspolar elements 602 is shown.

Considering the coupling between the adjacent crossed polarized elements 601 emitting vertically polarized waves by the aperture radiation structure according to one embodiment, a value as low as about -20 dB is confirmed on the basis of 60.00 [GHz] . It can be seen that the numerical values above are such that the cross-polarization coupling 602 is negligible with a very low value and does not affect the beamforming of the antenna array.

The coupling between adjacent identical polarized elements 602 emitting a horizontal polarized wave by the progressive wave radiating structure according to an embodiment shows that a value as low as about -12 dB is confirmed on the basis of 60.00 [GHz] have. Because the antenna has the same polarization, the coupling value is relatively high compared to the coupling value of the same polarized elements, but as a whole is very low, the same polarized coupling 602 is negligible, It can be seen that the beamforming of the array is not affected.

Referring to FIG. 12B, there is shown impedance matching for the vertical polarization 604 according to the aperture radiation structure and impedance matching for the horizontal polarization 603 according to the progressive wave type radiation structure.

The graph is an impedance chart showing 50 ohm matching on a Smith chart, and the portion denoted by Center 1.0 is a 50 ohm area. Each value is a value obtained by normalizing the complex number indicated by = R + jX.

The antenna cross-polarized coupling according to the present invention is negligible and does not affect the beamforming of the antenna array since it can be analyzed that the impedance matching is good when the lines shown in the graph are near 1.0. Can be confirmed. The impedance matching according to the present invention can provide maximization of power transmission and minimization of parasitic signal reflections.

The dual-polarized ports 702 may be coupled to a polarizer 706. The feed dual-polarized ports 702 may be implemented by a monolithic integration technique.

As shown in FIG. 16B, the polarizer 706 may include a polarization filter 704 that varies the direction of electromagnetic waves passing through the interior of the electronic device. Therefore, the vertically polarized electromagnetic wave and / or the horizontally polarized electromagnetic wave can be independently radiated through the polarizing filter 704 of the polarizer 706.
