When [L.sub.pg] = 0.6 mm, the return loss
is less than 10 dB but the bandwidth is 4.7 to 13.0 GHz which is less than the desired bandwidth.
The measured and simulated return losses
of the second antenna are presented in Figure 10.
To understand their effects, the return loss
profile is investigated with different slot length (Ls) and width (Ws).
Although, 2 mm x 5 mm slots achieved lower return loss
value but the bandwidths are narrower in both upper and lower bands.
The return loss
of the antenna with and without parasitic element obtained by using Ansoft HFSS V13 shows in Figure 3(b).
Figure 9 shows the variation of return loss
with a reduction in the gap 'g' in the defected ground plane.
As depicted in Figure 6(a), when the slot is located at x-axis, significant changes in return loss
and frequency can be seen when the width of the 'zig-zag' slot, Wsiot is varied from 0.5 mm to 2.0 mm.
For the latch to be secure, it is important to use the best quality connectors, such as the Winchester Electronics Din which has a return loss
of 20db @ 3Ghz and better than 15db @ 6Ghz--if there is not to be a risk that vibration results in a less-than-perfect contact, which may take the return loss
out of specification for digital video.
and insertion loss are two of the new terms that will be used more and more by the mainstream to characterize and describe the performance of interconnects in the GHz regime.
Power-handling is typically 60 W CW forward, 10 W CW reverse with minimum isolation and return loss
of 20 dB, and maximum insertion loss of 0.3 dB.
The six-member V-Bite Series is engineered to provide signal integrity in RF applications, and includes an "F" Type offering up to-40.3 dB return loss
at 2.3 GHz, a threaded through-panel BNC, twin BNC, standard BNC, and TNC version along with the new unit.
They are also temperature stable, with a low return loss
and low frequency drift.
