I still have question why E and H planes are messed up in many places (just googled for E-plane H-plane patch antenna arrays):
1)

In this paper we can see 14 x 6 patch array. Feeding lines goes to patches from bottom side, so i E-plane must be vertical. It is 6 patches direction, and beam is wider than in horizontal direction. But from fig.8 we can see, that E-field pattern is narrower than H-field pattern!

Here is 1x4 element patch array. Feeding lines from the bottom side of patches. Again guessing E-plane is vertical. There is 4 patches in vertical direction and only one in horizontal, so guessing that horizontal (H-plane) beam is wider than vertical (E-plane) beam. It is true if we look at fig.2. But in characteristics on page 3 it is written that E-plane is horizontal! Again messed up.

Here and many other x-band doppler modules like HB100. In datasheet we can see that E-plane is narrower than H-plane. But when we look at patch array, it have 1x2 elements, and 2 elements in H-plane direction. So H-plane must be narrower. If i google for "HB100 module h plane" then i found many pages stating similar thing:
**broken link removed** E-plane=36deg H-plane=72deg. This sensor have two separate antenna arrays. One for transmit, one for receive. One array is 1x2 pathes (2-patches in H-plane). So H-plane must be narrower! But from datasheet we can see that E-plane is narrower.
4) This one seems right:
**broken link removed** (microwave-solutions.com). This sensor have two similar antennas, one for transmitting, on for receiving. One patch array size is 2x4 elements. Patch feeding line is from right side of patches, so guessing that E-plane is horisontal. Also E-plane have only two patches, so it must be wider radiation pattern than H-plane (4 patches). From electrical characteristics table on page 2 we can see E-plane 36deg, H-plane 18deg. So here things are not messed up.

On the page 2 there is microstrip patch array of 2x1 elements. E-plane 50deg, H-plane 80deg. But there is two patches in H-plane direction, so H-plane must be narrower.

This one seems right, and also it have E-plane orientation on the page 84. E-plane is vertical with feeding line at patch bottom.

This one seems right. H-plane is narrow, and fieeding line from the bottom. Many elements in H-plane direction.
Maybe it is messed up because of misinterpreting E,H,V, etc. in plane marking?
E-plane (electrical field), can be misinterpreted as Elevation-plane.
H-plane (magnetic vield), can be misinterpreted as Horisontal-plane.
