The bandwidth limitation of antennas is usually linked to their input impedance because it is the quantity which changes with frequency so improvement in impedance response can help us to enhance its bandwidth. This approach can be implemented into following broad categories:

Lastly in section (C), path loss exponents are same as that of section (B) but the distance from transmitter and receiver are varied for individual value of path loss exponent. From the graph, it shows us that for n=2, the distance of reduced output power is in the range from 0.1 to 1.5km, similarly for n=3 it is in the range of 1.5 to 2.5 km, and for n=4 it is from 2.5 to

The upper sideband is fc +FM where fc is the carrier frequency and FM is the modulation (audio) frequency .The lower sideband is fc – FM. The total bandwidth is 2*FM

3.1.2 Active Filters: It inject equal and opposite harmonics onto the power system to cancel those generated by other equipment. Remarkable advances in the field of power electronics had sparked interest in APF for harmonic distortion mitigation. The basic technology of APF is to use power electronics technologies to produce the harmonic current components such that the source will supply only the fundamental part of

In this work, we consider an eNB with Ne antennas and K UEs with Nr antennas operating in FD mode (fig.1). For the proposed architecture shown in Fig.2 and Fig.3 for eNB and UE respectively, the Analog and Digital SIC unit, includes analog and digital cancellation stages described in [10,11] for implementing SIC.

There are several substrate materials that can be used for fabrication antenna. Some of them are low cost while the others are highly expensive. Each substrate being used has its own advantages and disadvantages. The dielectric of each substrate plays an important role in the

The band pass FIR digital filter has been analysed with hanning window by using FDA tool in the MATLAB. The cut off frequency has been estimated by using nn tool.

One solution for multi frequency operation is to design different antennas for each frequency, results in bulky structure and the mutual coupling between different feed elements will become a problem. Stack structure is the solution to achieve multiple band operation with

comparison of mean square error using feed forward back propagation (FFBP) and radial basis function(RBF) neural network algorithms are given in table 5.2 for analysis of band pass FIR filter with hanning window.

The characteristics are expressed either by time domain impulse response h(t,ϴtx,Ѱtx) or by the frequency domain transfer function H(f,ϴtx,Ѱtx) . thye dispersion of an antenna can be analysed by regarding the analytic impulse response, which is calculated by Hilbert transform.

In the recent years, progress in computational and experimental millimeter-wave electronics has identify the millimeter-wave (MmW) frequency band as highly promising for a number of high-resolution and high-speed wireless systems [1]–[6]. In specific, the unlicensed 57–64 GHz band is of strong interest for high data rate Gbps

The rectangular microstrip patch antenna on the unity permittivity substrate within the internal U-shaped slot. Recently, the researchers had proposed the similar design on the microwave substrate, that was better preserve the thin profile characteristics. These researches had focused the almost entirely on the top plate of the antenna element, while the effect of the size of the ground plane on which they are mounted had not been the fully studied. According to the published literature reducing the size of the ground plane and the making of the ground plane resonate at the desired frequency, both the bandwidth enhancement and the size reduction could be

When the filling material is homogenous ieε1=ε2=2ε0 the patch has its resonance at f=w/2π=2.12GHz.However loading patch with an ENG material can reduce the resonance frequency in principle without limits.When permittivity ε2=-2ε0,the rasonsnce frequency may be made arbitrarily low.The value of plasma frequency

In this paper, they have developed a dual frequency printed dipole rectenna for the wireless power transmission at 2.45 & 5.8 GHz. For operating at dual band, a novel uniplanar printed dipole antenna is created using a coupling method. In this combination of low pass filter and bandstop filters effectively blocked the higher order harmonic re-radiations [11].
