ABSTRACT Mobile phones are most common way of communication and accessing Internet based services. Sending and receiving sensitive data are not only used for proper communication at mobile phones. However, the security of mobile communication has topped the list of concerns for mobile phone users. So Public key cryptography is effective security solution to provide […]

ABSTRACT Microstrip realization of beam forming network integrated with dual-band antenna array on silicon substrate is presented. Design and implementation of broad band topologies of hybrid and phase shifter are discussed and further integrated to realize wideband 4× 4 Butler matrix. Proposed wideband Butler matrix is used to realize single-band and dual band antenna architectures […]

ABSTRACT This paper presents a detailed design and development methodology of Gun-Collector Test Module (GCTM) for 6 MW peak and 24 kW average power, S-band klystron. Electron gun has been designed through Vaughn’s synthesis, which was later optimized using TRAK code. The final optimized design was cross verified using MAGIC code. Thermal design of the […]

ABSTRACT An entirely new technique has been designed to couple the advantages of both the microstrip patch antenna and rectangular waveguide. Patch antenna consists of two patches, one radiator patch which faces outside, and the other faces mouth of the rectangular waveguide. Antenna parameters like return loss, gain, bandwidth, polarization and radiation pattern were studied […]

ABSTRACT Research organizations all over the world are finding and developing more and more application areas for UAV’s. The prominent areas where UAV’s have marked their presence include largely military, air force and upper atmosphere exploration. Presently the technology involved in military application Quadcopter is inaccessible and secret, thus in this paper attempt has been […]

ABSTRACT According to the constitution of India justice is an important part in which a consumer justice and protection is one subpart. There are number of legislations were passed by the Indian Parliament but they fail to protect the interest of small consumers. In the Consumer Protection Act, 1986 was passed, to protect the interest […]

ABSTRACT A manual vision detection system is used in earlier days of detection of plastic mulching films in the cotton. With the arrival and the advancement of technology, A machine vision system is being used under which an image processing based software programs are there which will run the target image in different ways. This […]

ABSTRACT The present paper discusses the comparative dielectric constant and dielectric loss of black pepper and white pepper within frequency range 10 kHz and 10 MHz and temperature between 300C to 510C. Impedance gain/phase analyser (HP 4194 A) was used to measure the dielectric constant and the dielectric loss and Julabo (temperature controller, F-25, Germany) […]

ABSTRACT This paper presents a design of Rectangular Fractal microstrip patch antenna using Iteration Methods by cutting different slots on rectangular microstrip antenna and experimentally studied on IE3D software This design is achieved by using three stages of iteration and  a Probe feed This design has been studied in 3 iterations The radiation pattern of […]

ABSTRACT This research paper investigates the Ergodic capacity of MIMO-OFDM system in Rayleigh Fading Channel to increase the Ergodic Capacity of the system. Orthogonal Frequency Division Multiplexing (OFDM) is multicarrier modulation technique for transmission of signals over wireless channel. OFDM, using multiple sub carriers divides the available spectrum into number of sub orthogonal sub channels. […]
