Microstrip radiators are expanded because of its utilization in high operating frequency and fast information correspondence applications. A microstrip radiator for X-band satellite application is proposed in this paper. The design of antennas for satellite applications differs in several respects from other applications. The major function of a satellite antenna is communication. Accurate predictions are required to design an efficient antenna system. The design required to consider the important antenna parameters like radiation, gain, front to back ratio and impedance. The planar patch antenna provides better gain, VSWR, return loss and radiation efficiency parameters. The total dimensions of the proposed Leaf shape antenna as 15 x 12.3 x 0.787 mm3 and Roger RT Duroid 5880 is used as a dielectric substrate of the proposed antenna. Analytical and design results are obtained using 3D electromagnetic simulator termed as CST Microwave Studio Suite 2017, based on Finite Integration Technique (FIT). The FIT is probably the numerical method for electromagnetic field simulation with the most dynamic development. The FIT is a spatial discretization scheme to numerically solve electromagnetic field problems in time and frequency domain. The resulting matrix equations of the discretized fields can be used for efficient numerical simulations.
This paper involves in the designing of Hexagonal microstrip antenna with H-tree fractal slots for biomedical applications. Skin cancer a deadly disease which identified early can be cured. The key application of this work is to detect cancerous tumors present in patients without skin contact. The design works with the help of electromagnetic waves directed towards human skin. The Hexagonal microstrip antenna with H-tree fractal slots is used which operates in multiband. The ground plane of the antenna is etched to increase bandwidth to enhance the performance of the antenna. The resonating frequency of the designed antenna is 2.71GHz and 4.21GHz.
The main aim of the proposal is to enhance overall capacity of the passive optical network, by increasing Wavelength Division Multiplexing (WDM) channels. The objective of this paper is to demonstrate the technique to generate Optical Flat comb spectrum (OFCS) with the help of Amplitude Modulator (AM) and Single Drive Mach Zehnder Modulator (SDMZM). The OFCS generated through this technique will have 51 spectral lines with very less power difference between them. Both (AM and MZM) modulators are driven by the same RF frequency of 30 GHz and proper DC biasing is given for MZM to get very flat spectral carriers. The OFCS generated by this method can be used in WDM-PON system which can serve large number of users. Each carrier out of 51 spectral lines is capable of supporting greater than 10 Gbps Quadrature Amplitude Modulation based data with the help of Orthogonal Frequency Division Multiplexing (OFDM) sub-carriers.
The motivation behind this project is to aid the visually challenged to navigate within the indoor environment with considerable ease. The system is designed on the premise that the user's movements are confined to well-defined locations that can be studied and modeled with reasonable accuracy. The objectives of this system are to help the user reach a destination and keep him informed on his current location while alerting him on any obstacle or hazard on his path. This project is implemented is based on the RFID technology and IR sensor. To implement this application, RFID tags are arranged in each room. Whenever the person is in a room, the RFID reader will detect the room and the person can reach another room by giving voice commands or by pressing switches. The MATLAB environment identifies the voice command and then generates proper voice command instructions to the user to reach the destination. The system is designed would be tested on the premise where the user's movements are well-defined that can be studied and modeled with reasonable accuracy.
Smart grid is the new concept that has emerged from traditional grid. The traditional grid is having unidirectional flow of information and also having some problems like power depletion, rising power requirement, healing, consistency and most important safety. Smart grid replaced regular grid and presented bidirectional flow of energy from service providers to end users. Smart grid deals with power production, transmission, distribution and consumption. It employs different gadgets for observing, analyzing, and regulating the network. Different types of sensors, actuators and smart meters are used for analyzing the network using internet connectivity, computerization plus chasing of such gadgets. This all can be implemented only by using Internet of Things (IoT). This new technique relates people with things every moment anywhere. IoT is having a lot of applications such as intelligent transportation, environmental monitoring etc., out of which the most important application promotes the development of smart grid. IoT technique combines all the available resources in communication and electrical power system, enhancing the level of information of power network, and monitors the consumption and usage of existing infrastructures of the present grid. The requirements related to the implementation of smart grid with IoT with suitable devices are discussed in this paper.
