,,,where did you see this...???

This difference, increases the bandwidth and increases the distance between directors can increase the gain of the antenna.

,,,, but the dimensions are for the centre frequency f0 = 7.74 GHz...!!!! ,,,for 2,442GHz LA=WA=275mm or 545mm....so the antenna will be very large...!!!!

Clanon, you can create circular polarization by using cross dipoles. like crossed dipole or crossed bow tie antenna. moreover you can create CP by truncating stubing and sloting in a patch.You can get a circular polarisation with a planar spiral antenna which has the same circuit modelling of a dipole but with CP. For 2.4GHz sbf-antenna is very large in diameter(580mm)...!!!

,,,much better...!!! ,,, from this idea... ,,, and these are the dimensions of the antenna...

,,, be attentive to the coaxial cable portion with 75Ohm impedance...!!!

Sham, it would be nice if you read this...https://fpvlab.com/forums/showthread.php?3626-Crosshair-10-dbic-Circularly-polarized-antenna-tutorial! ,,, normally,it comes to 180 grd...!!! ,,,, and these would be the dimensions for some working frequencies... ,,, if you want an antenna on the frequency of 1280MHx,maybe I can help you

I don't remember this post anymore, but I think I also gave dimensions..!!

I think it is not an octagon with equal sides...!!!

I can not find, show me where on the forum ... !!!

Clanon, from where did you get these pictures...???

,,,вы можете взять трансформатор из Ремо...!!!

,,, why ... ??? ,,,all elements should be excited in-phase...!!! ,,,and it is best to make the adjustment with the inclined sides...

"Sorry, I took care of Remo, but it solves your problem ... !!!

Panel antenna MIMO ZETA BOX with a sealed box for USB 3G/4G modems is a ready solution for signal amplification LTE1800, UMTS2100, LTE2600, WIFI2400, GSM1800. Antenna type - common-mode grating of broadband vibrators. Recommended for use at the boundaries of the service areas, in low and unstable level of 4G/3G signal.

,,, after modifying the dimensions of those submitted by Nickol, it appears that the simulation results correspond to those of manufacture...

Panel antenna "BAS-2324 FLAT-15F MiMo" is designed for use in conjunction with the equipment of wireless data transmission systems standards 2G(GSM1800), 3G (WCDMA2100), 4G(WIMAX LTE2600). 4G LTE antenna allows to implement the MIMO technology (Multiple Input Multiple Output), significantly improving the stability and sustainability of the equipment and increase the speed of data transmission. Equipped with two F-connectors for easy and quick connection of feeder lines. The antenna is directional (beam width is 30°/30°). When installing the antenna it is important to know the right direction to the base station of your provider. The antenna is equipped with two F-connectorsthat allows to connect almost any hardware (to connect to modems require appropriate adapters and/or cables), the connectors are structurally closed DC, which provides protection of connected equipment from static electricity. FEATURES The location of the antenna:External Supported communication standards:GSM1800, WCDMA2100 (3G), IEEE802.11b/g/n (WiFi), LTE2600 (4G) Operating frequencies, MHz:1700 - 2700 Gain max dBi:15 The wave resistance, Ohm:75 Maximum input power, watts:40 Connector type:2 F-connector Assembled dimensions (without mount), mm:240x240x40 Weight, max, kg:1

,, спасибо ... !!!!

Nickol, be careful how you position the transmission lines...

These are the results after a first simulation...

With the special input of the user "nickol.belousow2017" , I will try to simulate this PANEL 3G/LTE ANTENNA "BAS-2324 FLAT-15F MIMO"

I think we should move the current topic to the topic..."Remo Street Connect 3G/4G Universal" That's about the dimensions...

Nickol, if you pick up two such antennas and give up the adaptive lines for port2 and also make the horizontal adjustment between them, you will get an antenna with a gain of 17dBi..
