,,, it seems that still matters that shortcut, for low frequencies...

-
,,, it might be better that way ...

I did that many years ago.,,,!!! Batwing antenna,it"s the best...

Clanon, no longer shows to the kid, nonsense with biquad antenna,,,,!!!

A compact wideband high gain directional antenna is proposed in this paper for wireless communications. The antenna consists of a back plane (reflector), a slot-loop antenna (driven element), and a director of rod. Based on the current distribution, the slot-loop antenna is equivalent to an array of three linear current dipoles. The dipole acts as an element of the director, which provides a high efficient director for slot-loop antenna according to theoretical analysis.,, Source here...https://www.semanticscholar.org/paper/A-Compact-Wideband-Slot-Loop-Directional-Antenna-Chi-Qi/8b49e8ca70eac53c89963a7838de611bf2600af0?tab=abstract&citingPapersSort=is-influential&citingPapersLimit=10&citingPapersOffset=0&year[0]=&year[1]=&citedPapersSort=is-influential&citedPapersLimit=10&citedPapersOffset=10

DESCRIPTION Room of highly focused wifi antenna "WiFi AGENT" allows you to increase the reception range of a Wi-Fi signal in the desired direction, thanks to a powerful built-in antenna and built-in Wi-Fi adapter. Gives you the ability to access remote Wi-Fi household or public network at speeds up to 150 Mbps. FEATURES The location of the antenna:Room Support communications standards:Wi-Fi (IEEE 802.11 b/g/n/) Operating frequencies, MHz:2400 Gain max dBi:15 Cable length, m:1.8 Connector type:USB 2.0 type B Built-in Wi-Fi adapter :Yes Assembled dimensions (without mount), mm:234х190х25 Weight, max, kg:0.45 Package dimensions, mm:270х295х35 Gross weight, kg:0.6 Transfer rate, UL/DL, Mbit/s:150 Easy to install. The connection is via the supplied USB cable. If you experience problems with automatic detection of connection and "WiFi AGENT" to your PC use the supplied driver disk.

,,,later...!!!

,,,, and what you want for me...???
-
,,, and why are you telling me this ... ?? ,,, because this antenna is a fake ... ???

,,,no, the isolation is a measure of how well the two ports are separated from each other in terms of unwanted signal coupling. 30dB isolation is in most cases considered 'high isolation'(s21. s12 =aprox.30dB) The port-to-port isolation is defined as the ratio between the power fed into one port of the antenna and received at the other port. Ideally one would like the two ports to be completely independent (infinite isolation) because the signal 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. ,,,for satellite dish, I think the best is the Batwing antenna(it"s broadband)...!!!
-
AUREL, you're right buddy....!!! I will post a simulation of this fake antenna a little later ... !!!
-
,,, it's a bullshit ,,,!!! I simulated something like that many years ago...!!!
-
,,, maybe only so, for circular polarization... ,,,but with other dimensions...!!!!
-
That would be the geometry of the antenna....
-
... I can't ,,,, with 4 gb of ram your pc has to work...!!!
-
Clanon, try to install cst2020(or 2019)...!!!
