,,,this simple welding device can be useful for gluing antenna plates...!!!
-
,,,for this antenna... fig1a-side rhombus1 = 0.25 * lambda fig1b-side rhombus1 = 0.25 * lambda -side rhombus 2 = 0.5 * lambda fig1c-side rhombus 2 = 0.5 * lambda ,,,it would seem that a diminished form would be so.... (this is my idea...!!!!) ,,,for fig1c, it must be tried this...!!!
-
,,,,where from...!!!!
-
Yes, of course...!!!

,,,no...!!!
-
,,, the gain is the same but a better focus results...!!! But, I think the best solution is this...
-
I don't think so, let's see...!!! yah,10dBi...
-
But I think it would be better 110x120x30mm
-
", first move it down, and then resize the reflector ...!!!
-
,,,he probably refers to it, but anyway. must open another topic...!!!

-
Charlesopisp...here, it's not about the fractal loop antenna...!!!
-
Eric, let me do a simulation and then see...!!! ,,,,but you see that the patch antenna is not in the center of the pyramid trunk (reflector)...!!!

Kroks Rt-Pot sHw DS modem Huawei E3372, built-in antenna For installation in offset dish on a mast on the wall or on the window sill. Built-in WiFi antenna 2.4 GHz. 4G speed up to 70 Mbps, 3G up to 35 Mbit/s Power DC 24V twisted-pair. Kroks Rt-Pot sHw DS is a router with 4G the modem and the illuminator built into one housing. The router has several types of mounts included in the package. Private gain of the radiator is 8-9 dB. The operating frequency is in the range of 1700-2700 MHz. MIMO technology supported by the irradiator in the entire frequency range, dual channel bandwidth. The device is running OpenWRT operating system that provides bandwidth allocation (QoS), firewall, user access control and many other features. mPCI modem allows you to get the maximum possible speed 4G Internet that may not always provide a USB modem. Built-in WiFi antenna, support 2.4 GHz standards 802.11 b/g/n and provide communications range up to 50 meters in open range.

,,,read this..http://www.antenna-theory.com/definitions/sparameters.php The port-to-port isolation is defined as the ratio between the power fed into one port of the antenna to the power received at the other port. It is therefore an important parameter to consider if the antenna is to be used with a transmitter that makes use of MIMO. Ideally one would like the two ports to be completely independent (infinite isolation) because then what ever signal is transmitted from one port will not interfere with the signal transmitted from the other port. The lower the isolation, the more interference there will be between the two transmitted signals.

,,s21,s12 it"s not good,", for this antenna is not recommended...!!!
-
,,,,, who is Mike ... ???

,,, ready, that this is the end of this topic ... !!! ,,,tomorrow I will give the dimensions...!!! ,,, below are simulated 1 + 1 pepperbox antenna at a distance of 123mm... ,,, twine crosshair antenna...!!!
