The cross antenna is a medium gain and circular polarization structure made of a conductor or a strip line over the ground plane following a cross contour of four or more branches.The construction repeatability is verry easy as well the facility to obtain 14dBi gain in a small antenna.

,,,now I'm trying to reduce it a little but with the same results...

Hello everyone.Here are proven horns for offsets at 5.4 Ghz offset 60cm . horn5,4ghz.cst

Yes, if you find something like that....

Have a router with built in modem Huawei B683. Used in the country, the range is 2400 there clean. All anything, but Wi-fi gives it worse than a smartphone, the plot is not even enough, although installed in the wooden deck solder the pigtails and screw conventional pipettes from any router.Track is better to cut, as this connector is not found, and if found, it will break with the first poke. In extreme cases, all easy to restore in place

U.FL (‘U’ stands for ultra-small and ‘FL’ is just a series name assigned by Hirose) connectors are commonly used in gateways and end devices where space is of critical concern (similar: I-PEX, IPX, etc).

,,,okay,I will try....!!! Yes, so be it...???

Almost done, but not very good... ,,and with more patches...

,,,not yet, but in the future...!!!

Radiation patterns and gain measurements on 1.0, 1.5, and 2.0 lambda backfire Yagi antennas are given. The backfire antenna was tested for two dipole feed locations, and variations in the diameters of the two planar reflectors forming the backfire cavity. The optimum dimensions of the three test antennas are tabulated. The frequency bandwidth of the backfire antenna is limited to several percent due to impedance matching. The backfire antenna should find application in broadside arrays where conventional endfire antennas are presently used. 19680012807.pdf

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.

In telecommunications, a collinear antenna array is an array of dipole antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear, that is they are located along a common line or axis. Collinear arrays of dipoles are high gain omnidirectional antennas. A dipole has an omnidirectional radiation pattern when in free space and not influenced by any other conductors in that it radiates equal radio power in all azimuthal directions perpendicular to the antenna, with the signal strength dropping to zero on the antenna axis. The purpose of stacking multiple dipoles in a vertical collinear array is to increase the power radiated in horizontal directions and reduce the power radiated into the sky or down toward the earth, where it is wasted. They radiate vertically polarized radio waves. Theoretically, when stacking idealised lossless dipole antennas in such a fashion, doubling their number will produce double the gain, with an increase of 3.01 dB. In practice, the gain realized will be below this due to imperfect radiation spread and losses.

okay, I'll try.

For documentation, I think this should be studied... matecconf_icesti2018_01042.pdf ,,,dual element triangle patch microstrip antenna for WLAN 2.4 GHz....!!!!

,,,for clanon... stl.stl

Your file is completely wrong...!!!

Okay, now post the images with the results obtained...!!!

Okay, then post the results...!!!

I think it's easier to post the CST file....!!!

,,,but you need to show the positioning of the power point and the thickness of the PCB...!!!

,,,hi buddy...!!! welcome to this forum...!!! if you can give some dimensions it would be better! Gerber files are from CST-Studio...??? And why don't you write in normal letters?
