,,, such as dual band,,,??, maybe, cross polarization...!!!

,,, that's what it would look like ... !!! ,,,by o_pylypenko...!!!

This is an article edited by the user "com666", for which, I would like to thank them....!!! The range of mobile communications covers a wide frequency band. The bands LTE800, LTE900, LTE1800, LTE2600 are already used to transmit LTE signals in Russia. 3G signals are transmitted in the ranges wcdma900, wcdma2100. To receive mobile signals in these ranges you need broadband antennas. Among industrial designs, it is difficult to find simple and repetitive designs. Most often, antenna manufacturers use separate antennas for the low-frequency and high-frequency parts of the range to cover the entire range and combine them with a frequency-dependent combiner. This approach has many disadvantages, such as: The design of the antenna is much more complicated. The hardest thing to do is a filter adder. The area occupied by the antenna is increasing. Losses from summing ranges are growing. Examples of such antennas in the photo below. SHYAM Antenna for 900 + 1800 Dual Band Repeater: However, full coverage of all ranges of mobile communications is not provided. There is a need for a simple broadband design with the overlap of the entire range of mobile communications 800-1700 MHz. Here is an example of such an antenna: The antenna is a modernized broadband Batwing, 1945 patent. "Batwing Super-Turnstile Antenna US Patent Number: 2480153 Year: 1945 Inventor: Robert W. Masters Original Document: US Patent Number 2480153 " There is a mention of this antenna at Rothamel in the book "Antennas" The antenna sheet can be cut from a flat galvanized sheet, 0.7 mm in one pass with a laser cutter. Additionally, you need to solder or rivet the cables from the same material with a size of 34x14mm. The antenna uses two flat square screens: Lower 220x220, above 95x95. Specifications:

I checked a V-shaped vibrator and it seems to give good results, the MIMO version remains to be tried...!!! This ensures uniformity of impedance over a large frequency band.

,,, you can bend the galvanized sheet like this ... ,,,or like this...

,,, it is possible, but you do not get the same gain...!!!!

,,, is a copy of Petra20...

,,,another bend shape...https://www.youtube.com/watch?v=6DqHlFrHhg0

,,,the best Batwing....

The high gain directional wideband antenna is suitable for directional radio signal transmission and reception, signal source reconnaissance and direction finding, broadband signal testing and the like. The antenna is suitable for UWB positioning module, Wifi2.4G and 5.8GHz and other common frequencies. Antenna indicators: Frequency range: 2.4GHZz-10.5GHz Dimensions: 100mm*85mm Polarization mode: linear polarization Rated gain: 7dBi Return loss: 10dB Power capacity: 8W Interface form: SMA female head (outer screw inner hole) Package included: 1 x 2.4-10.5GHz UWB Directional High Gain Wideband TEM Antenna

,,,yes...

Of course...!!!

Jossip,if I understand you want something like that....

Okay, I'll try to do that...!!!

,, not really, it is welded on the back of the double plated circuit...!!!

,,,dual band and single band WiFi-Flat Antenna...

D1=45x45mm

This high gain multiband 4G omni antenna is designed for 800MHz (2G / 4G), 900Mhz (4G), 1800MHz (3G / 4G), 2100MHz (4G) and 2600MHz (4G) frequency band and supports all established standards like GSM, 2G, 3G and 4G (800 / 900 / 1800 / 2100 / 2600). The antenna has a gain of up to 12dBi and helps you to improve your 2G, 3G or 4G connection even on long distances. This 4G antenna works perfectly with LTE / 4G devices which have external antenna port. Compatible 4G Routers with external SMA female antenna port: - Telekom Speedport LTE, Speedport LTE II - Telekom Speedbox LTE, SpeedBox LTE II, SpeedBox LTE III - Telekom Speedport Hybrid - Vodafone Easybox 904 LTE - Vodafone B1000, B2000, B3000 - Vodafone LTE-Modem - Vodafone LTE-Turbobox LG FM300 - O2 LTE Router - FritzBox LTE- Router (except FritzBox LTE 6842) - D-Link DWR-921 - Huawei B390, B593, B890 - Huawei E5186 - Teltonika RUT230, RUT240, RUT550, RUT950, RUT955 - Many more... Optionally we offer a pair of antenna cables of type LMR200 with a length of 2.5m, 5m, 10m and 15m with N male to SMA male (fits to the most common LTE routers - see list above) connectors. The enclosure of the antenna is made of solid plastic and stainless steel. The robust, light weight and UV resistant construction is weatherproof. This allows to use this 4G antenna for outdoor appliances. The antenna is designed for mast/pole or wall handle installation. A mounting kit (angle bracket and u-clamp for 30-50mm diameter handles) is included.
