    ,,,these would be the results...

    to see the axial ratio in CST, you should look at "Farfields" section in the simulated results... there should be a drop down list after simulating the design.

    if you click on that drop down list you should be able to see the axial ratio plot...

    The default plot is in 3D format, if you want to plot it on polar form, you need to right click on a farfield result and select "Far field plot properties", In the "General" tab select "polar" for the "plot type" and choose the values for "Theta" & "Phi" according to the orientation of your design. Then select "apply" to see the results

    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 TL-WA5210G outdoor high-power Access Point (CPE) is designed for creating long-distance wireless networks, as well as for use as a solution when accessing the Internet via a wireless Internet Service Provider (WISP). This model combines the functions of a Wireless access Point, a WISP Client, is equipped with a highly sensitive antenna and is made in an all-weather housing to protect against environmental conditions. The high output power and high sensitivity of the 12 dBi antenna can significantly increase the data transmission range and provide a more stable wireless connection. The device supports the IEEE 802.11 b / g standard and allows you to create a wireless network with a data transfer rate of up to 54 Mbit / s, so that all network users can share files and browse Internet sites.
