3.7-7GHz UWB Horn Antenna
Ultra-Wideband (also known as UWB) is a low power digital wireless technology for transmitting large amounts of digital data over a wide spectrum of frequency bands typically spanning more than 500MHz with very low power for short distances.
The low power requirements of UWB mean increased battery life of sensors and tags leading to a reduction in overall operational costs. Taoglas has developed various innovative and new-to-market UWB antennas designed for seamless integration with the recently launched Decawave ScenSor DW1000 module and is also compatible with any other UWB sensor modules on the market.
The PHA.01.A is a high gain UWB antenna designed to provide long range coverage at the sensor side and less susceptibility to interference due to low sidelobe rejection, (> 15 dB) relative to peak boresight gain. It is designed to cover UWB band 2 and 5 frequencies and does not excite other higher order modes in its frequency band of operation.
A well-designed time-domain antenna should accurately reproduce the time waveform of the incoming field, thus preserving the amplitude and phase of the incoming signal. In order to provide desirable time-domain fidelity, an antenna must have both a constant amplitude response and a linear phase response in the frequency domain. The PHA.01.A antenna exhibits both high Fidelity Factor, >0.9 and also minimal phase ripple, less than 65 ps, making it ideal for UWB communications.
The TEM horn antenna is designed to introduce minimal waveform distortion by allowing the fields within the structure to remain in the dominant transverse electromagnetic mode. By designing these antennas specifically for use with impulsive time-domain signals and having a broad frequency spectrum, time-domain distortion can be minimized.
