Features 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. 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. 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. 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. 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. Feature: 1. 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. Specification: Item Type: Wideband Directive Antenna Material: PCB Mode: R101C Basic Parameters and Their Explanations: Frequency Range: 730MHz-6.5GHz The R101C antenna has good transmission and reception performance throughout the entire frequency range. The standing wave rate is less than 2.0 and has good gain. When the frequency range is exceeded, the gain and return loss of the antenna will rapidly decrease, and the usage requirements will also be correspondingly reduced. When the standing wave ratio is less than 2.5, it can be used up to 700Mz to 7GHz. Mechanical Parameters: Interface Type: SMA external thread, internal needle Polarization Mode: Linear polarization Input Impedance: 50 Ω Working Conditions: Temperature Range: -45 ℃ to 80 ℃ Humidity Range: 0% to 95%, allowing short term 100 percent, without splashing Waterproof Performance: Dry after spraying, replace the connecting wire after soaking Wind Resistance Performance: For safety reasons, it is prohibited to use when the wind speed is greater than 20m/s (wind force level 8) Package List: 1 x Antenna Module Package List 1 x Antenna
