Jomy maybe YOU can post an animation (GIF) of the ENERGY flowing through the driven Disk surface...(to see it turn...)
-
the cable position is a NO-NO...imho
-
the materials maybe... Material: galvanized iron + powder enamel. (easy to copy and test...)

Brass might be better not so easy to oxidize...or protected from moisture PURE COPPER...(aluminum, zinc,etc) You'll have bigger losses on DIELECTRICS than metal every time

40mhz for SPEED (ideal conditions no loss of Packets or jumping signal strenghth) , 20 for stability (bad conditions , reflections , etc on 2,4ghz tho 5.8ghz is a different beast)

PS: the cPE210 with a better antenna could have worked better than the 5ghz one...imho 15 dbi at least and Free LineOfSight...
-
what are the Huawei specs...model (that's HALF the network...) walls take at least 3db (depending in lots of factor Thickness materials metal is worse) the cpe has a lot of gain and needs a perfect alignment...but the router you are accesing needs to be free of metal obstacles on the LineOfSight...if possible otherwise you end up pointing to reflections and quality degrades a lot (passing vehicles cut MY connection sometimes Line of sight obstructed)

MikroTik QRT 5 is a dual-polarization 5 GHz microstrip panel antenna with a gain specified up to 24 dBi and integrated radio at just 31×32×5 cm size The plastic case looks quite robust and UV resistant. The microstrip antenna array inside consists of 64 elements (8×8), which result in 10.5° beamwidth (-3 dB). There is also a MikroTik RB911G-5HPnD-QRT board, which features a 2×2 MIMO 802.11an radio (AR9342 SoC) with 30 dBm tx power. The antenna is connected with two short MMCX pigtails.

i'll say all Dielectric Boom tube...Polycarbonate (ABS) for sure...

Integrated LNA amp for Interference finding...All PET PC Boom tube...? Catalogo-Antenne-di-Misura-e-Monitoraggio-Monitoring-Protel-023.pdf

couldn't find it (was on a catalog) this is similar https://www.protel-antennas.com/files/22-Amplified-portable-antenna-ARK103XZ-PROTEL-HANDHELD-INTERFERENCE-FINDER-GSM-LTE-DCS-UMTS-data-sheet.pdf https://www.protel-antennas.com/protel-ark103xz-amplified-directional-measurement-antenna-band-lte-dcs-umts-1350-2200-mhz.html

Trying to make a "GOOD" Lpda , SCIFI VIVALDIs from RFSPACE have NO GAIN (under 1GHZ) , Chinese LPDAs have LOTS of LOSSES and mismatch...50 ohms FLAT ALL band , just a peak close to 1ghz unavoidable on this antennas...
-
Still testing , Imepdance needs some work still...But looks good so far) Copper tape under 40 cm long and wide...PES foam or PU foam dielectric
-
@eco32 you NEED to try CST...is very intuitive and fast...and better results... backfiring CIRCULAR PATCH should have better shape...LOBE
-
add a rim and ring...
-
PES (Styrofoam) low density...1.075-1.1 Dielectric Constant (almost NO LOSSES)
