DESIGN OF RECTANGULAR SHAPED SLOTTED MICRO STRIP ANTENNA FOR TRIPLE FREQUENCY OPERATION FOR WIRELESS APPLICATION

This Paper represents the designing of the Tri- Band Rectangular Printed micro strip Antenna. One amongst the simplest feeding technique is employed i.e. coaxial feeding technique for feeding the antenna Tri band antenna is obtained by etching two quarter wavelength rectangular shaped slots inside the patch at the proper position to resonate over GSM, Bluetooth and Wi- MAX. The proposed antenna is realized on FR-4 dielectric substrate having a dielectric constant of 4.4 and loss tangent of 0.02, with dimensions of 46x38x1.6mm3. The design calculations are done for the frequency of 2.4 GHz. The designed antenna is simulated using EM simulation software CAD FEKO suite (7.0). The antenna covers the three bands of operation i.e. GSM (1.834-1.858GHz), Bluetooth (2.422- 2.487GHz), Wi-Max (3.519-3.583GHz) with reflection coefficient ≤-10dB. The overall simulation results shows that the antenna gives good impedance matching at desired frequencies with VSWR≤2.Also the radiation pattern, efficiency,gain and impedance for all four frequencies are investigated using simulation results.

A REVIEW PAPER ON DESIGN FOR MICROSTRIP PATCH ANTENNA

Microstrip patch antenna is mostly used in modern communication devices over conventional antennas mainly because of their size. In this review paper a survey is conducted on commonly used techniques and design used in microstrip antenna papers which has been used by authors for designing of an efficient, low profile, small, compatible, affordable microstrip antenna, mainly used to designed reconfigurable, multiband and wideband antennas, after that a initiator patch design is given with dimensions on which technique will be applied for the analysis of different parameter of antenna.

PORTABLE PKL POWERED LANTERN

It has been designed and developed the portable PKL (Pathor Kuchi Leaf) lantern for practical utilization for smart grid where grid electricity is absent. The PKL converter has been made with an insulated box and electrodes. The electrolytes were prepared by PKL extract. It was found that the portable lanterns were appropriate for PKL electric system. It is found that PKL Powered Lantern has been working well. The novelty of this research work shows that this type of work is very new one in the world. It can be used instead of solar PV sometimes. There are some advantages of this PKL systems compare to SPV (Solar Photo Voltaic) System. This PKL system can be used equally both for the rainy and night time. Whereas SPV system is not possible to use at the rainy and night time.

STUDY OF INTEGRATION TECHNIQUE OF OPTICAL DRA ANTENNA FOR VARIOUS BAND

The dielectric resonator antenna technologies are applicable to design various band level or various types of simulation with low return loss of antenna design. In this paper we have taken several aspect ion of antenna results which has been investigated. The Research Article Concentrated on optical DRA Antenna and performance simulation result is improved with some configurable improvement. The wireless communication system has mainly demanding requirements to improve return loss. Antenna made up of materials has abled to improve its potential performance with high level enhancement. Although most of the optical antenna use 5 nm or less than 5 nm diameters because carbon nanotube become superior conductor at 5 nm diameters. Optical antenna is substitute of traditional antenna or generate model antenna. Which include light – matter interaction, absorption & emission of light which can control its special direction as well as control of its complex non analytic algorithms they behave like strong coupled light emitting devices like photovoltaic.
