(NASDAQ: NXPI) and Volkswagen have shared early glimpses into Ultra-Wideband (UWB
) technology and its future applications.
BlueCats uses a variety of edge technologies, including UWB
, BLE, global-positioning system (GPS) sensor data and RFID.
There are many reasons for UWB
, such as comparison with others, work stress, goal setting, and role conflict (Hershcovis & Barling, 2010; Schweitzer, Ordonez, & Douma, 2004).
Finally, the optimization of Antenna 4 has been conducted in CST based on the criteria that, the reflexion coefficient is close to -5 dB over the filtered bands, while it is less than -10 dB over the rest parts of UWB
MIMO antenna in  could achieve a mutual coupling larger than 20 dB in the entire operating band by etching a T-shaped slot as well as a narrow slot on the ground plane.
Moreover, if the third notched band acts as a spurious resonance and is not desired, one can push it up away from the UWB
band to maintain the UWB
performance of the antenna by enlarging the ratio between W2 and W1.
signal transmission in a tropical atmosphere layer will experience attenuation, phase shift, and the addition of delay time.
Therefore the optimum value of 'Wr' chosen in order to reject the WIMAX band is 1.0mm on which the antenna operates from 2.76GHz to 11.78GHz covering the entire UWB
(3.1GHz to 10.6GHz) and rejecting from 3.20GHz to 3.96GHz which covers the undesired WIMAX band (3.3GHz to 3.8GHz).
On the other hand, UWB
is lightweight platform, hence detection and interception of UWB
signal (due to the low "[T.sub.x]" power) is relatively complex Figure 3.
