“…Among the key elements constituting the PCBs, the viaholes are playing an important role to design highperformance packaged components and PCBs [4][5][6][7][8][9][10][11][12][13][14][15]. The via enables to simplify and to shorten the connections between different components at optimized position of PCBs.…”

“…The via models were exploited to improve the performance and to optimize design PCBs especially in multilayer technology [10][11]. The vias are useful to miniaturize high-frequency circuits to realize certain microwave functions as filters [14][15]. However, the utilities of via for classical RF and microwave functions are well-known topics in the area of packaging engineering, electromagnetic compatibility (EMC), signal integrity (SI) [16][17] and in integrated circuit design [18][19][20].…”

“…The novelty of the present study is answering to this typical research curiosity for understanding how a via element is susceptible to behave as a low-pass NGD function. Despite the popularity of via integration in HD PCBs [4][5][6][7][8][9][10][11][12][13][14][15][16][17], curious questions were legitimately wondered by research engineers considering emerging circuit topologies as electronic NGD functions. In the best of the author's knowledge, nowadays, the design of NGD circuit based on via-hole is not available in the literature.…”

The via ground (GND) structure constitutes one of the most useful elements for designing high performance printed circuit boards (PCBs). The electrical interconnections with vias become key regular solutions for the implementation of various electronic functions. However, so far, the vias are never being used for designing negative group delay (NGD) circuit. To answer this curious question, an original study on the design feasibility of low-pass NGD function with via ground is introduced in the present paper. After the topological description, the NGD analysis in function of the via parameters is established. The design equations allowing to synthesize the via in function of NGD function specifications are formulated. The developed NGD theory is verified with comparisons between calculations and simulations with a commercial tool. As expected, NGD value in order of hundred-picoseconds over hundred-megahertz cut-off frequencies is obtained with good agreement between the theoretical model and simulation. Furthermore, time domain analyses confirm that the via NGD structure enables to generate output signals in timeadvance of arbitrary waveform input signals presenting limited bandwidth.INDEX TERMS analytical modelling, cylindrical via, Low-pass negative group delay (NGD), microstrip circuit, via-hole ground.

“…A microstrip patch antenna with a feed line connector operating at 2.5 GHz has been studied in [9] for the reception of signal from the unmanned vehicle and many communications application. A compact size with sharp cutoff and low insertion loss, low pass filter is presented in [10] using square and rectangular complementary split-ring resonator etched to ground layer to get a new metamaterial filter. Research by Reja et al [11] a microstrip bandpass filter with regular slots is presented along with two transmission zeros and frequency response as compared with single-mode resonator.…”

A magnetron is a power oscillator device used in several radar transmitters for generating the electromagnetic wave (EMW) with a constructive and fixed frequency. In this work, a radar transmitter has been carried out using magnetron operates at 2,458 MHz and two conducting layers waveguides to achieve minimum loss of the signal due to the increased temperature. The magnetron is connected with the high voltage capacitor (1.0 μF) in order to store the alternating current (AC) signal delivered from the high voltage transformer. A waveguide parts have been used as transmission lines in view of connecting the magnetron to the antenna. These parts include two metal layers, the upper layer (outer) is advanced audio coding (AAC) 1350 aluminum conductor and the lower (inner) is copper. The waveguide dimension should be suitable to flow frequency from 2.2 GHz to 3.3 GHz. To measure the operating frequency, a waveguide adapter and a coaxial cable which combined with n-female connector have been connected to magnetron. The wave is delivering to the frequency counter by Bayonet Neill–Concelman (BNC) to n-female connectors. The promising results of the proposed work have been achieved with a maximum power, efficient return loss, acceptable voltage standing wave ratio (VSWR) and low-cost manufacturing.
