Of course, with a bucket we are trying to "step twice into the same river". Discussion metal bucket as the horn has already been discussed on the internet. It is obvious that to draw energy from the twice same amount of space is impossible. Please note that the effectiveness of the example is superior to the dual mirror system and is comparable with them on bandwidth supports. Use galvanized buckets as the mouthpiece, which probably can be discussed in detail . And in this example, dispelled some myths. In particular, square (rectangular) patch element easier to manufacture at home, allows you to easily build wideband antenna and can be used in circular polarization. And here are the achievements of some predecessors...

A method to improve the gain of axial-mode helical antenna is proposed. This method involves a parasitical circular metal disk,which is installed on the front of general axial-mode helical antenna and is apart from the helical line. A circular current whose phase lags behind that of helical line current appears,which brings a more concentrated radiation field. Consequently,the antenna gain is improved, Based on the simulation results,an antenna array model fed independently is proposed.This model gives an excellent explanation of the radiation characteristic of helical antenna, Both the simulation and experiment results show that for obtaining the same gain,the antenna length in this new method is only 71% of that in traditional helical antenna.The reduction of antenna length favors the miniaturisation of antenna. In addition, this method has a little effect on the bandwidth of antenna, so it can be widely used in the design of helical antenna element and array.

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.

Irradiator series BOF-2xxx is designed for use with standard metal, satellite parabolic offset mirror. The utilization of mirror surface is more than 0.7. The radiator is optimized for mirror with f/d=0.5÷0.7 and the angle of irradiation 75÷90 degrees. (The vast majority of satellite dishes on the market.) The plane of polarization of the antenna is changed by changing the position of the radiator to the mounting site. (Rotation, followed by fixing in position.) Polarization direction is indicated by an arrow (the arrow) on the casing of the irradiator. The direction of polarization of the radiator and antenna are the same, because after reflection from the reflector, the vector of linear polarization is not changed. With circular polarization, upon reflection from the mirror direction of rotation is reversed! ,,, this is a MiMo simulation irradiator, the antenna can be on different frequency range

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.

Here are some quick notes about the parabolic type dish antennas you might find. The actual antenna is a normal half wave dipole with an integrated balun and is located inside the sealed plastic cover. The mesh screen is the reflector which concentrates the RF energy onto the antenna. That is how dish antennas increase the received or transmitted power level. Also, wireless cable service providers frown upon giving away their used dishes as they think you're going to steal cable service.

It would be good if the focal length(F/D) was also shown for each antenna grid...!!!

There are no differences, except that the feed must be performed differently, to ensure a good impedance match. One can even build rectangular plate Yagi-Uda"s, and make the elements slot antenna elements. Also, a different feed is required for that.
