ITEM NAME:3-10Ghz 5W UWB Ultra Wideband High Gain Transmission Linear Antenna Broadband Product Description Feature: Working frequency: 3-10G Transmitting power: 5W Voltage standing wave: less than 2.5 Gain: 2.5 Technical characteristics of UWB: (1) High transmission rate and large space capacity. (2) Suitable for short-distance communication. (3) Good coexistence and confidentiality. (4) Strong multipath resolution and high positioning accuracy. (5) Small size and low power consumption. UWB pulse forming technology: Any digital communication system must utilize a signal that is well matched to the channel to carry information. For linear modulation systems, the modulated signals can be uniformly represented as: s(t)=∑Ing(t -T ) (3) Wherein In is a sequence of discrete data symbols carrying information; T is a duration of data symbols; g(t) is a time domain shaping waveform. The operating frequency band, signal bandwidth, radiation spectral density, out-of-band radiation, transmission performance, implementation complexity and other factors of the communication system depend on the design of g(t). For UWB communication systems, the bandwidth of the shaped signal g(t) must be greater than 500 MHz and the signal energy should be concentrated in the 3.1 GHz to 10.6 GHz band. Early UWB systems used nanosecond/sub-nanosecond carrierless Gaussian single-cycle pulses with a signal spectrum concentrated below 2 GHz. The FCC's redefinition of UWB and the allocation of spectrum resources put new requirements on signal shaping, and the signal shaping scheme must be adjusted. In recent years, many effective methods have emerged, such as carrier modulation based forming techniques, Hermit orthogonal pulse shaping, and ellipsoidal wave (PSWF) orthogonal pulse shaping.
