The purpose of this paper is to design a microstrip patch antenna with low pass filter for efficient rectenna design this structure having the property of rejecting higher harmonics than 2GHz. As the design frequency is 2GHz.in first step we design a patch antenna in second step we design patch antenna with low pass filter and combine these two. The IE3D software is used for the simulation of t...

Microstrip antennas are widely used in many applications due to their low profile, low cost and ease of fabrication. In some applications it is desired to have a dual band or multiband characteristics. These characteristics can be obtained by coupling multiple radiating elements or by using tuning devices such as varactor diodes [1, 2]. However, these methods make antenna more complicated. A si...

The properties of the Koch island fractal boundary microstrip patch antenna are presented. The behavior at the fundamental mode and the existence of high-order modes that exhibit localized current density distributions is discussed. The main features are the size reduction of the patch resonating at the fundamental frequency when compared to Euclidean-shaped patches, and the application of loca...

Triangular latt ice Electromagnetic Band-Gap (EBG) St ructure in the ground plane is used in the design of a Triangular Microstrip Patch Antenna (TMPA) Array to improve its bandwidth. The patch elements are equilateral t riangular in shape. The Equilateral Triangular Microstrip Patch Antenna (ETMPA) Array design has four patch elements in 2×2 form with ground plane having circular cutouts formi...

In this paper, an Artificial Neural Networks (ANN) model has been developed to design the multilayer Rectangular microstrip patch. In the design procedure, synthesis ANN model is used as feed forward network to calculate the resonant frequency. Analysis ANN model is used as the reverse side of the problem to calculate the antenna dimension. The network is trained with the data obtained from mea...

In this paper, an active integrated antenna (AIA) system is proposed for mobile and wireless communication devices. The AIA system consists of a microstrip patch antenna and a low noise amplifier (LNA), which are integrated together with a matching circuit and printed on an FR4 PCB circuit board. The system is designed, analyzed, and optimized by targeting to satisfy the design specifications f...

Microstrip antenna is gathering a lot of interest in communication systems. In this paper neural network approach has been used for calculation of feed position of microstrip antenna for maximum power transfer. This paper demonstrates the validity of neural network for the estimation of feed point of patch antenna varying with input impedance. Accuracy of the results encourages the use of Neura...

In recent years, the application of radio frequency identification (RFID) operating in the ultra-high frequency (UHF) band (860-960MHz) are expanding exponentially, due to the advantages such as long reading distance, high data transfer rate, and small tag size. So the design of a CP tag antenna with broadband characteristic is presently one of the most challenging topics. This project presents...

A novel radio channel compensation method aiming to give optimal calibration for microstrip antenna array systems is presented in this paper, realized for an actual DOA measurement antenna system using microstrip antennas to sample the electromagnetic field, operating at 4.5GHz. This new approach considers mismatch between antennas and channel RF ports, channel transmission inequalities, and al...
