Hello, it would be good if you could post some dimensions for this dual band antenna...!!!!

DavidER,finally, I managed to complete this antenna,.with 75 0hm impedance(1,95---2,2 GHz)...

,,, may I try today ... !!!

,,,why solder a wire, that's where the antennas are connected...!!!

,,,as you can see, the modem has two plugs for connecting antennas...!!!

,, is this what it looks like built from PCB...???

,,,why this difference in the location of the ports...???

Recently,a new antenna configuration known as Bow Tie Antenna (BTA) or Butterfly Antenna(BFA) are proposed with broadband and high gain properties . The Butterfly Antenna is shaped from four side quadrilateral sheet feed in the vertex. This kind of antenna is defined by quadrilateral the flare angle only.

TL-WN821N is a portable Wi-Fi adapter that can connect via USB to computers and laptops to connect through it with your home router (access point) and safely surf the Internet with speeds up to 300 Mbps. In that situations will it be useful to make a modification,,,

GSM antenna "Razor" is designed to amplify, stabilize the signal and provide high-speed Internet for modems and routers. If the signal in your area is not as good as you would like, the 3G/4G "Razor" GSM antenna will improve the quality of signal reception at a distance of up to 20 km. from the base tower! The operating frequency range is 1700-2200MHz (3G-2100MHz, 4G LTE-1800MHz). The antenna can be installed outdoors, on a pipe, or just on the wall on the side of the base station. If the Internet speed does not suit you, you need to change the antenna mounting location. It attaches quickly and easily. The kit includes step-by-step instructions on how to install the antenna correctly.

,,,something to try...

,,, the frequency of 4.5 GHz is not visible...???

Panel antenna MIMO 2x2 AGATA is intended for use in complete equipment of wireless data transmission systems standards: 2G(EDGE, GPRS frequencies GSM1800) 3G (UMTS 2100) 4G (WIMAX,LTE1800, LTE2600) WI-FI (IEEE 802.11 b, g, n) in other systems the range of 1700-2700 MHz. AGATA MIMO 2x2 antenna is highly directional and ideal for use in communication systems "point to point" and "point-multipoint". Antenna is a structure of two spaced in-phase arrays with orthogonal polarizations.

,,,maybe later...!!!

,,, yes it is possible, I told you before...!!!

Petra-10 MIMO 4x4-Universal compact panel antenna for 4G / 5G modems and routers that support MIMO 4x4 technology. F=1700-5000MHz, CU=7-12dBi, connectors 4 x N-female, X-pol, decoupling between channels of more than 20dB. The PETRA-10 MIMO 4x4 panel antenna is designed for use in a set of equipment for 4G (B1, B3, B7, B38, B40) and 5G (N77, N79, N78) wireless data transmission systems at frequencies of 1700-5000 MHz. This antenna is compatible with MIMO 4x4 equipment, as it has four connectors for connecting to the equipment. You can also connect two modems with MIMO 2x2 technology to the antenna for redundancy/summation of communication channels. Advantages of the PETRA-10 MIMO 4x4 antenna : The wide band of the antenna allows you to work in all current and future fastest cellular communication bands Full support for MIMO 4x4 technology. Active emitters are reliably protected from precipitation by a housing made of UV-resistant plastic and have an extended service life The antenna inputs are short-circuited by direct current between the external and internal conductors, which reduces the probability of static electricity accumulation at the modem input and makes the use of a lightning arrester optional (with a small length of the connecting feeder between the modem and the antenna).

,,,by Harry36 user.... For manufacturing, you will need galvanized iron with a thickness of 0.5 mm (no more, this is due to the height of the patch above the reflector), two SMA connectors, an M8 bolt, an M8 nut, an aluminum pipe with a diameter of 8 mm, and foamed PVC. The design is relatively easy for home production, even a round element of this diameter will not be difficult to cut with metal scissors. Follow all the dimensions and recommendations as accurately as possible and you will have a great antenna.
