Design and Analysis of Rectangular Microstrip Patch Array Antenna for ISM Band Applications
Abstract: In this paper, we have achieved an efficient rectangular patch antenna with optimized parameters. Antennas are key components of any wireless system. A microstrip patch antenna (MPA) is a small size antenna used to process ultrahigh frequency signals. A microstrip antenna is commonly called as patch antenna and here we are using rectangular patch. The conducting patch can take any shape, but rectangular configurations are the most commonly used. The …

Broadbanding of Circular Patch Antenna Using Stub Loaded Stacked Configuration
Abstract: This paper proposes a stub loaded stacked configuration of a circular patch antenna using FR-4 material as a substrate with dielectric constant of 4.2 for resonant frequency of 2 GHz. This configuration is a hybrid of two broadbanding technique, the stub loading technique and stacking technique. The radius of the patch is calculated to be 18.88 mm and the air gap is 1 mm between the lower and upper layer. …

A Simple Method for Estimation of Surface Transfer Impedance of Coaxial Cables as Per MIL STD 1377 for EMC Qualification
Abstract: In recent years, electromagnetic compatibility (EMC) problems associated with high frequency and high speed inter connects are becoming of increasing concern. Coaxial cables are a popular form of inter connect between intra- and intersystems and subsystems. Transfer impedance is a measure for assessing the shielding effectiveness of outer shield of a coaxial cable. In this paper, we proposed an easy and inexpensive method for estimating the surface transfer impedance (STI) …

Design A Kaiser Window Based Digital Filter by Using GRNN
Abstract: In this paper, we have designed the digital filter based on Kaiser Window function using ANN. Firstly we have designed the 10th order digital filter based on Kaiser Window function then calculate the coefficient of designed filter. Similarly this process is repeated for the 15th and 20th order. We have normalized the frequency and designed filter at frequency ranges 0.05 to 0.95 Hz. Then we calculated the coefficients of filter …

Rectangular Microstrip Antenna Design and Analysis for Exposure System at 900 MHz with Different Feeding Mechanism
Abstract: Microstrip antennas widely used in defence applications, in aircrafts and in applications where narrow bandwidth is required. In this work an antenna is designed with 3 different feeding mechanisms. The feeding mechanism is used to provide the path for the flow of current from the source. The three different feeds are Line feed, Quarter wave transformer feed and Inset feed. The rectangular microstrip patch antenna designed at 900 MHz and …
