I took over the redesign of this antenna and I came up with this version...

,,,the antenna looks very good but it would be interesting to see its feed points (inside)...!!!

,,, type of antenna,not very easy to produce , but with good results in circular polarization. Between the patch and irradiated put plate of polystyrene or polyurethane...

This panel rectangular 4+4 patch antenna can also give you better performance because of its high peak gain of 19dBi. {recommended for drone tracking antennas} overall dimensions=120x200x10mm The antenna patches are suspended on a polystyrene dielectric...

The high quality Patch antenna for 5.8GHz receiver. Can increase the range of 5.8GHz transmitter This 5.8GHz Right-Hand (RHCP) Circular Polarized patch antenna was custom-designed for the FPV market. Light enough to be mounted directly onto an FPV headset including the FatShark Goggle system or Uno and Duo FPV receivers. With a much wider beam than it's 13dBi cousin, it easily has double the range of a standard SpiroNET Omni antenna. Specs: Circular Polarization: Right-Hand Band: 5.8GHz ISM Gain: 8dBi Beam width: -3dB at +/- 45 degrees (H + V) (90 degree total) F/B Ratio: >356dB VSWR: < 1:1.35 at 5800MHz Impedance: 50 ohms Weight: 7g

,,,it is easier to solder a coaxial cable to the feed point...!!!

Technical specification for manufacture of powerful antennas and high gain exclusively for FPV needs was consistent with the known Scientific-Production Center. The centre has a serious scientific potential, SOOOOO expensive equipment, modern production base and its patented production technology. The guys have been designing and manufacturing aerials for over 15 years and know about antennas just about anything, have experience of working with domestic manufacturers of UAV, FPV, therefore, subject them in part familiar and in this respect they have certain practices. Just what we needed: 1) Create an antenna that would have a large gain, comparable with the antenna "Yagi" in the popular FPV range 1160-1280Mhz. 2) To the antenna form factor was close to a patch antenna (for ease of placement on a tripod) 3) had an adequate angle of orientation, eliminating the need to use the rotary system for tracking the model at long distances Antenna gain from a 14.7 dB at the extreme frequencies of the range 1160Mhz 1280Mhz. Not difficult to guess that the gain in the middle of this range is significantly higher (the guys understand the task "literally"). This reinforcement is "not theoretical" and measured on real devices, on average, it in two times better than any patch. 2) the Antenna has dimensions of 400х400х25мм (including the case) 3) the Angle of orientation of the antenna about 40 degrees, which is not bad. Specifications : The most effective frequency range: 1160-1280Mhz The gain in the effective frequency range: 14,7 dB VSWR: less than 1.5 Polarization: linear vertical The radiation pattern Vert/Horiz: 40/40 degrees Input impedance: 50 Ohm Connector: N-type "mother" Weight: 2kg As we can see, the antenna is a... rather strange design four groups oval active elements. Between them the special material. The reflector is a metal substrate, the active elements in each group, TWO(!!!) (instead of one in the classic patch).

,,,take this... sputnik1400.cst

,,,but this antenna does not have the 1200-1600 MHz band..!!! ,,,this is what the antenna you want should look like...!!!

,,,for this frequency range it still seems like a big antenna to me...!!!!

,,,for which frequency band do you want the antenna to be...???

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.

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.

The original design of the balun device, protected by patent, contains a bandpass filter, which is well agree on the antenna cable in the operating frequency range, reduces noise at its output and provides reliable lightning protection TV. This design of antenna is designed for reception of television decimeter waves (UHF) frequency range 470-862 MHz, allows us to keep the analog (21-69к)and digital (DVB-T/T2) signals. The antenna is passive and does not have a built-in amplifier in this regard does not require electric power 220 volts. If you need to increase the level of the received signal external power amplifier can be installed separately.
