Recent research has shown that the integration of a custom-silicon network-on-chip (NoC) into an FPGA fabric can significantly help on-chip communication bandwidth. Although not appropriate for all communication, FPGA hard NoCs provide a scalable infrastructure that will increase in importance as FPGA sizes increase. To date, most FPGA hard NoC implementation has focused on packet-switched routing...
The paper proposes an Ultra Wide Band (UWB) Planar Inverted F Antenna (PIFA) for Body Area Network (BAN) applications. A tapered feed is also introduced in order to overcome the narrow band characteristics of PIFA. The two shorting pins are introduced in the middle of the patch to enhance bandwidth performance. The proposed antenna has a low profile structure with overall size of 32mm × 36mm × 8mm...
In this paper a small size wideband planar inverted-F antenna (PIFA) is proposed which operates at 4G LTE (2.3–2.4 GHz) and (2.5–2.7 GHz), Bluetooth/WLAN (2.4–2485 GHz) and WiMAX (3.4–3.6 GHz) range. The proposed antenna has many advantages like small size and wide operation bandwidth. The antenna portion has dimensions as 20mm * 18mm and the overall dimensions are 44mm * 25mm * 0.8mm which can be...
Thispaper describes the design of a wideband acquisition technique for a Quadrature Phase Shift Keying (QPSK) demodulator. The demodulator is designed at a frequency of 70 MHz to cater data rates up to 6 Mbps. The most important requirement of the design process is to have wide acquisition range of ±125 KHz under narrow Phase Lock Loop (PLL) bandwidth and low input Signal to Noise Ratio (SNR). Hence,...
In this paper, an antenna for 4G and WLAN devices is proposed. The proposed antenna is designed using Planar Inverted F Antenna (PIFA) structure. The antenna uses Rogers Duroid 5880 as a dielectric substrate and metallic ground plane. The dimensions of the top patch are 18.5 mm × 18.5 mm and thus making it a low profile antenna. The designed antenna covers WLAN (2.4–2.48 GHz) & 4G LTE (2300–2400...
In the recent years, the demand for low profile, low cost and high performance antennas has increased due to rapid development of communication systems. This paper presents a parametric study on ground slotted microstrip patch antenna for X-band applications. In order to reduce the size of the proposed antenna, slots have been introduced on the patch and ground plane. Therefore the total size of the...
There is an upsurge for miniaturized antenna that covers maximum number of frequencies in the communication technologies. Fractal antennas have been pondered as a promising field due to space filling and self repetitive properties. In this presented paper a study is made on modified Koch geometry to obtain multiband behavior. It is observed that rise in each level of iteration, results in increase...
Compact and multiband antennas are effectively demanded in wireless handheld devices for multiband operations. The design of multiband Planar Inverted-F Antenna (PIFA) for mobile handheld or portable devices applications is presented in this paper. The designed antenna comprises of a rectangular planar element placed above the Rogers Duroid 5880 substrate. The ground plane resides at the bottom side...
Detecting and classifying objects in sidescan sonar images is an important underwater application with relevance to naval transportation and defense. Properties of the imaging modality, in this case, often introduce large intraclass variabilities reducing the discriminative power of any classification algorithm and limiting the possibilities of improving classification accuracy by advances in pattern...
