R101C broadband antenna is a printed tapered slot line antenna. It is suitable for directional radio signal transmission and reception, signal source reconnaissance and direction finding, broadband signal testing and other purposes.
The antenna covers the common frequencies of radio frequency units such as mobile phone communications, UWB positioning modules and Wifi. The antenna has good directivity, high gain and small size. The rear end of the antenna is provided with a mounting hole. In addition to independent use, the antenna can be fixed at the focal position of the parabolic reflector as the feed source of the parabolic antenna.
R101C has stable performance and high product consistency. It is an indispensable experimental tool for radio frequency workers.
Basic parameters and their explanation:
●Frequency range: 730MHz-6.5GHz
The R101C antenna has good transmitting and receiving performance in the entire frequency range. The standing wave ratio is less than 2.0 and has good gain. When the frequency range is exceeded, the antenna gain and return loss will decrease rapidly, and the use requirements will be appropriately reduced. Standing wave When the ratio is less than 2.5, it can be used up to 700Mz-7GHz.
●Polarization method: linear polarization
The R101C antenna is a linear polarization antenna. The polarization direction is the vertical direction, which is the same as the vertical monopole antenna.
●Rated gain: 7dBi
The gain of the R101C antenna increases slowly as the frequency increases. It is about 5dBi at about 800Mhz, about 7dBi at 2.4GHz, and about 9dBi at 5.8GHz.
●Return loss: 10dB
The R101C antenna input impedance is 50 ohms, and when the 50 ohm impedance is connected to the signal source, the fluctuation is below 10dB in the frequency range, and the corresponding standing wave ratio is about less than 2.0
●Power capacity: 5 watts
When using the R101C antenna as the transmitting antenna, we recommend that the RF input power should not be greater than 5W. Short-term use can exceed 50W without causing damage to the antenna.
●Direction sensitivity
R101C has good directivity in the whole segment, and the side lobe is small. Can be used as a direction-finding antenna. The antenna pattern is wide in the horizontal direction, with a -3dB width of about 60°; in the elevation direction, the pattern is narrow, with a -3dB width of about 40°.

Safety Precautions:
●Be careful to touch live conductors when using, and be careful of electric shock
●Avoid using it outdoors during thunderstorms, especially when located in high mountains or wilderness, you should quickly go to a low place and lower the antenna
●It should be carried in a reliable way when climbing to prevent falling
●The antenna has edges and corners, so take care to prevent scratches when you carry it
●The antenna connector and feeder cannot bear weight. Avoid pulling during use. The feeder can be fixed in the fixed hole on the antenna with a cable tie.
Antenna maintenance:
●In actual use, in order to prolong the service life of the antenna, please pay attention to the following matters
●Avoid heavy pressure, collision, scratching the antenna
●Avoid bending the cable too much
●When unfolding the antenna stand, please place it on a horizontal plane to prevent it from falling
