,,,yes, both the central connector and the Teflon insulation can be shortened...!!! ,,,this is CST-file... N-P245 mufa.cst
-
,,,I considered it sensible to resume Aurel's idea from the beginning and to present a version of the Batwing wire antenna...

Here is another DIY antenna, this time for GSM/3G/4G usage. The design was calculated for 800-2100MHz and works well in this range. The antenna has a very broad bandwidth with a low gain and can be used for any application within the frequency range. Since the results are very good even up to 3GHz the antenna is also useful for WiFi. As well as ADS-B (flight radar) because 1090MHz is covered too. In general an excellent antenna for rtl-sdr operations. Based on this calculator.

By the addition of directors rings at a cantenna, can get better directivity...
-
V-shaped antenna in the air, without dielectric support...
-
,,,yes, it is better that way ,than putting a single antenna with two ports (MiMo)
-
,,yes,ZTE MF920VS, Frequency 2.4 GHz, Supports Bluetooth 802.11b, 2.4 GHz Radio Frequency ,,,but where does this modem have the connectors for the external antenna...???
-
gooood,,,for what frequencies were the antennas made...??? the biloop antenna needs a diameter of 40.5mm for the frequency of 2.442 GHz
-
,,,maybe you want something like this...
-
,,welcome,,,!!! ,,,so, for which frequency do I want the antenna panel..??? ,,,and MiMo to be...??? ,,,your antenna from the pdf file is not working well...!!!
-
,,,this tube diameter is not critical(20-30mm)...!! I will also give the dimensions of the Batwing antenna.
-
,,,and again I'm curious how right andrew mcneil is...???? I will try to do a simulation with this antenna
-
,,,the thickness of the material does not matter...!!! I think that in order to cover both frequencies(750 MHz;868 MHz), a single Batwing antenna should be used.
-
,,,antenna_kid, maybe you would be interested in something like this...
-
-
I don't know why but it seems similar to this...LINWLAN2,4GHz
-
I took up the idea of a single patch with a rectangular reflector with inclined wings...
-
I think it is best to make a Bester antenna for the desired frequencies....
-
antenna_kid,,,if you have any drawings, I would need more sizes...!!!
-
These are only some of my posts on other forums...!!! Last gif image is how to build an ellipse with line and compass....!!!
-
,,,but this... ,,, is different from this one... ,,,where did you get the pictures from?
-
-
I will try to resume this simulation... ,,,e.g...
-
,,,more gain>>>
-
,,,yes...!!!
