Do you want something like that...???

,,,good, but you have to know that for these frequencies the antenna will be quite big...!!!

,,,for 824-894 MHz....???

,,,no,PCB has poor results...!!!

Forget about PCB, it's not good...!!!

,,,no...!!!

I think it's understandable, this...

PETRA BB MIMO 2x2 UniBox is an antenna combined with a large sealed box (UniBox) which you can put any 3G/4G modem and even router. The antenna is provided with connectors - SMA-male. Included are two adapters to connect 3G/4G modems (the type of adapters to choose). The connection of modem to PC or router located in the room is via a USB extension cable. System UniBox - protects the modem from adverse weather conditions! Advantages: Universal antenna with excellent gain and operating in all high-speed standards Reliable fastening of the modem in the box Quality connectors for connection of modem and antenna Quality adapters with minimal losses Hermetically sealed Hardy and ultrafiol case material The possibility of repeated Assembly and disassembly of the box All set to launch the modem

,,,the antenna in the first figure has a wider frequency band...!!!

I'm still trying to make some optimizations for this kind of antenna. ,,,and yet it can be done better by doubling the distance "w"...

"I don't know exactly, it might exist on this site, but anyway I'll resume simulating this antenna...!!! Anyway, look here...

,,, is this true..??? https://www.amazon.com/dp/B0D75SNV2F/ref=sspa_dk_detail_0?pd_rd_i=B0D75SNV2F&pd_rd_w=O6n8b&content-id=amzn1.sym.953c7d66-4120-4d22-a777-f19dbfa69309&pf_rd_p=953c7d66-4120-4d22-a777-f19dbfa69309&pf_rd_r=972BGKJK8NP2YPEHWHCE&pd_rd_wg=hdh1C&pd_rd_r=1ceb8afb-1147-4e5d-8180-f7dc66314696&s=electronics&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWwy&th=1 ,,,with 16dBi gain SWR less than 1.8 and efficiency more than 75%....I don't really think so....!!!!!

,,,read this...https://www.quora.com/How-do-I-make-my-WiFi-router-accept-all-kinds-of-SIM-cards-The-router-is-not-locked-to-any-carrier-but-it-only-accepts-only-data-SIMs-and-the-SIM-card-I-want-to-use-has-phoning-abilities-as-well-so-it-doesnt-accept

,,,you must not have any obstacles in front of the antenna...!!!!

,,,for what 100 meter distance,to create a wifi bridge= Direct visibility, Distance 2.5 km.

Here's the problem, you have to keep this in mind....!!!

5.8 GHz 17dB High Gain AAT Automatic Antenna Tracker for HD FPV RC Racing Drone Product Description: Model: 5.8 GHz 17dB AAT Automatic Antenna Tracker Frequency Range: 5150-5950mhz Input impedance: 50Ω VSWR at surface level: <1.5 Antenna Gain: 17dBi HPBW (3dB): 16 ° H-plane 38 ° E-plane F/B:> 20 (dB) Max Power: 50W Polarization: Vertical polarization Connector Type: RP-SMA Static protection: DC ground Antenna Length (AAT): 30 cm Size: 136*68*10 mm Weight: 57g (Manual)/47g (AAT) Package included 1x5. 8 GHz 17 dB high gain

,,,and an improved version with elliptical patches... ,,,with wings...

Yes, there are two versions of the cantena, a simple one and a combined one.

Two long arms are connected in the shape of V to make a V-antenna. The two long arms are excited with 180˚ out of phase. As the length of these arms increases, the gain and directivity also increases. The following figure shows a V-antenna with the transmission line impedance z=200 Ohm and the lengh of the arm 0,8*lambda, making an angle Φm with the axis, which is called as apex angle.material-FR4 #1.5mm. The main advantage of a V-shaped antenna is its relatively small vertical radiation angle, which is especially important for establishing long-distance communications.

,,,it's also possible...with cantenna...

Yes, that's about it...still needs work...!11

Try this too ... 3.52-1ghz.cst

,,,see it...!!!

,,,you know how to work with cst-studio...???
