In the same work, simulations without experimental validation show how a return loss better than 40 dB could be reached for a 40% relative bandwidth
by using additional sections at one or both sides of the basic twist.
It can be seen that the proposed antenna achieves good impedance matching in a wide band, with the -10 dB impedance bandwidth being 2.8-4 GHz and the relative bandwidth
The MDRR scheduler provides relative bandwidth
guarantees and allows the definition of a low latency queue (LLQ), which is given priority over the set of standard queues and is mainly intended to support voice traffic.
From this expression, the relative bandwidth
is directly proportional to the inductance L and inversely proportional to the capacitance C.
Using CGH40025F transistor, we designed a power amplifier with the proposed architecture, which operates in range from 0.8 to 2.7 GHz with a relative bandwidth
Here, the UWB signal is defined as an absolute bandwidth larger than 500 MHz or a relative bandwidth
up to 20 %.
To achieve this, theory of relative bandwidth
(RBW) is applied here in a function of nominal center frequency, [f.sub.o], and transmission zero, [f.sub.tz]:
The -10dB return loss bandwidth is from 9.12 to 9.37 GHz and its relative bandwidth
As a matter of fact, in the configuration with the mirror coaxial cable the phase center is stable in the frequency band 4.25-13.25 GHz, with a relative bandwidth
greater than 100%, with a maximum variation equal to 28 mm.
In this paper, we present a 24.4% relative bandwidth
"bent" monopole MTM-based antenna for aeronautic applications.
