Abstract

In this paper, a fork shaped MIMO antenna has been proposed with an overall size of 26×40×0.8 mm , that is essentially used for the Ultra-WideBand (UWB) applications. It is fabricated on the FR_4 Epoxy substrate. The material has a dielectric constant of 4.4 and a loss tangent of 0.02 and the most important fact is that, it is very cheap and easily available. The proposed antenna consists of two fork shaped patch on the top surface of the substrate with a microstrip feed of 50Ω is positioned perpendicular to each other to attain good isolation. To increase the impedance bandwidth and to improve the isolation, two long ground stubs are placed on the bottom surface of the substrate. A small strip is used to connect the two ground planes together to form the common ground at the bottom surface. The performance of the fork shaped MIMO antenna can be measured in terms of the reflection coefficient at the two input ports, coupling between the input ports, peak gain and radiation pattern. The results show that the fork shaped MIMO antenna has an impedance bandwidth greater than 3.1 to 11.1 GHz with a low mutual coupling less than -15 dB throughout the band. It has a VSWR of less than 2, throughout the band and it has a good gain and an omnidirectional radiation pattern.

Abstract

A compact Ultra-WideBand (UWB) microstrip antenna is proposed for wireless application in the Ultra-WideBand (UWB) frequency. This paper proposed a low-profile antenna which consists of a patch, a combination of two inverted C-shape structures. This consists of a rectangular ground with one rectangular and one trapezoidal slot cut. Defected ground technique in this antenna provides a good impedance matching. The bandwidth of this antenna is broad which includes an entire UWB frequency range from 3.1 to 10.6 GHz. This antenna has three resonant bands 3.37 GHz, which is applicable for WiMAX (3.3 – 3.7 GHz), 5.3 GHz which is applicable for WLAN (5.15 – 5.825 GHz) and 10.06 GHz which is applicable for Amateur Radio (10 - 10.5 GHz). The surface size of antenna is 25 x 25 mm² with 1.6 mm height of substrate which provides broad bandwidth, constant group delay, good impedance matching and constant gain.

Abstract

I²C Multi Master with Multi Slave is designed from a bidirectional serial data bus containing bidirectional data lines like Serial Data Line (SDL) and Serial Clock Line (SCL) along with Wishbone Signal. I²C protocol has the ability to support multiple masters and provides an efficient method of data exchange between devices. This is a very useful protocol for faster devices to communicate each other with slower devices without data loss. With the use of this protocol, a serious problem arises resulting to overlapping of signals. To overcome such problems, a special signal called WishBone signal is used. The main objective of this paper is to observe the operation of the master controller and wishbone controller, which performs high speed data transfer in the presence of master or slave. This yields higher speed data transfer over the network. The complete module is modeled in Verilog HDL and synthesized in Xilinx 13.2i, also simulated in Model Sim 6.4a.

Abstract

This paper presents the performance of the Maximum Ratio Combining (MRC) technique for the downlink BPSK system. Generalized analytical Bit Error Rate (BER) is derived in closed form for imperfect channel estimators in complex flat fading environment. Analytical results show that BER depends on the cosine of estimated phase errors. Further, analytical and simulation results show that channel estimators are not required in real fading coefficients case, which is equivalent to perfect estimation case. In general, BER is defined in the range [0.5,1], but in this work complete range of BER i.e. [0,1] is related with estimated channel coefficients. However, the performance of two and more receiving antenna system slightly degrades as compared to the perfect channel estimator in real fading coefficients environment. Also, it has been shown that estimated amplitude coefficients have no effect on BER performance in a single antenna system, it’s only the estimated phase that matters; whereas for higher number of antennas, estimated amplitude as well as phase coefficients affect the BER performances.

Abstract

This paper describes the design and simulation of a Planar Inverted-F Antenna (PIFA) covering multiple bands by HFSS simulator. Simple structure and easy to manufacture is the key of the proposed antenna. It fulfills wireless communication application and also it is compact and efficient. The proposed antenna covers bands DCS (1710-1800 MHz), GSM (880- 960 MHz), PCS (1850-1990 MHZ), Bluetooth (2400 MHz), UMTS (1920-2170 MHz), WiBro (2300-2390 MHz), WCS band (2305-2320 MHz), LTE 2300 (2300-2400 MHz), LTE 2500 (2600-2690 GHz) and Wimax (2.3 GHz). A directional radiation pattern is observed within the mentioned bandwidth. S11 plot and various parametric analysis has been done for an improved response. The objective of this paper is to design a compact antenna, which could be used for different wireless applications such as mobile and should be compatible with the present demand, i.e. 3G and 4G.

Abstract

In this paper, a planar slotted microstrip antenna with rectangular slotted patch used as the single radiating element and tapered shape slot in ground has been designed and analyzed. The proposed antenna is compact in size with an 3 overall dimension of 22×24×1.6 mm . This antenna is fabricated on FR-4 epoxy substrate with relative permittivity of 4.4 and loss tangent of 0.02 and 50Ω. Resistance is used as the characteristics impedance for microstrip line feed, being compact in size, antenna still achieves a bandwidth of wide range from 3.6 GHz to 11.8 GHz. By properly adjusting the feed gap (h), that is the distance between the tuning stub and the slot in the ground plane, determines the coupling between them and a good impedance matching is obtained and by cutting two slots on the rectangular radiating patch, with dimensions 1.5×1 mm and 1.5×1.5 mm, the gain of the antenna is drastically improved and it is found that gain plot is above zero for frequency range of 8 GHz to 12 GHz and a maximum gain of 9.2 dB is obtained at 12 GHz frequency.
