19 dBi Directional Panel Antenna, RSLL
Additonal Legal Information
In this oustanding antenna we have redesigned the array of radiating elements in such way that antenna is highly immune for signals come from distant stations, outside of the mainbeam direction. This is because all noises and interfering signals are not collected by highly suppresed sidelobes of this unique antenna.
TetraAnt_2_19_20_RSLL delivers a very strong and clean (high S/N) microwave power even in the most interfering environement. Is is especially sufficent in the dense urban area with a lot of microwave networks. Because the pattern of antenna is the same for transmit and receive mode it also do not interfers with other networks.

The impedance matching for TetraAnt 2 19 20 RSLL microstrip WiFi antenna is better than 2.0 in bandwidth from 2.40 to 2.57 GHz.
Because the min. lower frequency and the max. upper frequency in 2.4 GHz Wi-Fi frequencies allowed by the FCC are 2.401 and 2.495 GHz, it's clearly visible that this antenna covers the entire Wi-Fi band.
Antenna patterns are usually shown in XY or pole coordinates, but this is not enough for fully understanding the radiation pattern of a given antenna. For example, some side lobes can be evident in other cuts like + - 45 degrees planes.
Fortunately we can see also 3D radiation patterns like this one taken at 2.45 GHz for TetraAnt 2 19 20 RSLL. As we can see, there are no evidence of the high level sidelobes at other cuts than that showed above in XY coordinates.
The direction of the maximum radiation is marked by the "hot" red colour. The simulation frequency was 2.45 GHz.
