Usually a Loop antenna exhibits a higher gain than a Yagi antenna with the same number of elements

Antenna-Bank (bandanna, banctenn, eng. cantenna) — name directional antennas-waveguide, made at home from tin cans. Typically used to extend the range of wireless devices.

This cantenna, presents some changes as it would be
1) plate vibrator
2) adding a directing element
3) attaching a cone to the cylinder

You can also use the simple vibrator....

You can position two  patches-antennas at 90 degrees for the MiMo antenna

patch for 2400MHz?

2,500 — 2,690 GHz

To watch...!!!

http://cheklab.ru/archives/3101

So you like it?

No, only the frequency range increases....!!!

300x300mm

or 360x300mm

And what do you want with these images for yagi antenna?

Okay, and finally, tell me what you want?

Something like that,,,,

,,,or like that....???

It's smaller than that

But I think for the LTE antenna , needs a circular or elliptical polarization...!!!

You need an antenna like this....

Jomy, on the first message shows the antenna from Vodkaman. This antenna options is hard to move to LTE band 5 and 18?

,,, then about 800-900 MHz ... ??

And of course other fractals

Fractal’ term was first coined by Benoit Mandelbrot in 1983 to classify the structure whose dimensions were not whole numbers. One of the properties of fractals geometry is that it can have an infinite length while fitting in a finite volume. The radiation characteristic of any electromagnetic radiator depends on electrical length of the structure. Using the property of fractal geometry, we may increase the electrical length of an antenna, keeping the volume of antenna same. There are an infinite number of possible geometries that are available to try as a design of fractal antenna.

One of the important benefits of fractal antenna is that we get more than one resonant band. The fractal concept can be used to reduce antenna size, such as the Koch dipole, Koch monopole, Koch loop, and Minkowski loop. Or, it can be used to achieve multiple bandwidth and increase bandwidth of each single band due to the self-similarity in the geometry, such as the Sierpinski dipole, Cantor slot patch, and fractal tree dipole.

The Simplest example of antenna using fractal geometry is given by the Von Koch, researcher. The method of creating this shape is to repeatedly replace each line segment with the following 4 line segments. The process starts with a single line segment and continues for ever. The first few iterations of this procedure are shown in below figure. Fractal dimension contains information about the self-similarity and the space-filling properties.

I design Hilbert Curves Fractal Antenna that use the co-planar wave guide feed.The first few iterations of Hilbert curves are shown below fig. This geometry is a space-Filling curve.

Starting from HDTV fractal antenna I simulated this type of antenna for wifi domain

Is this better?

Onmi-directional UWB antennas have been developed in the last decade

Wooww
It looks good.
But for better work, try to make the angle at the extreme point 25 degrees instead of 45 degrees. And the tips at the top of the arms must be 25 degrees outward. It must also be 25 degrees outward at the ends of the arms facing downward.

I will try to do it...!!!

I like it, the movies from the drones are made by you ...?

No, my friend
This is a variable option.
First you need to set the size of the dron and its purpose.
We will then make a list of engine esc and other equipment

For fun I ordered this,on the web...

Efe, tell me,  did you have plans for the practical execution of a drones..??

Reflector dimensions = 15x190x320mm
Reflector-Patches distance = 5mm

Below I present you a video made by my friend, Julungas.
It is a simple explanation of how to simulate in CST Studio, a sector antenna.
