1、MAIN FUNCTION: Printing gradient slot antenna. Suitable for directional wireless signal transmission and reception, signal source reconnaissance and direction finding, broadband signal testing, etc. Mainly used in laboratory environments. After connecting the handle, it can also be used for mobile direction finding. Stable performance and high product consistency are essential experimental tools for radio frequency workers. 2、EXCELLENT PERFORMANCE: The antenna covers the common frequencies of radio frequency units such as mobile communication, UWB positioning modules, and WiFi. The antenna has good directionality, high gain, and small size. 3、EASY TO INSTALL: The multifunctional bracket that supports the antenna can easily fix the antenna on the desktop or use it for handheld mobile use. 4、DUAL USE: The rear end of the antenna is equipped with mounting holes. In addition to independent use, the antenna can also be fixed at the focal point of the parabolic reflector as a feed source for the parabolic antenna. 5、DIRECTIONAL SENSITIVITY: R101C has good directional performance and small side lobes throughout the entire segment. It can be used as a direction finding antenna. The horizontal direction of the antenna pattern is relatively wide, with a ‑3dB width of approximately 60 °; In the angle of altitude direction, the directional pattern is very narrow, with a ‑3dB width of approximately 40°. 6、RETURN LOSS 10dB: The input impedance of the R101C antenna is 50 ohms. When the 50 ohm impedance is connected to the signal source, the fluctuation within the frequency range is less than 10dB, and the corresponding standing wave ratio is about 2.0.
