Abstract

In this paper, we have achieved an efficient rectangular patch antenna with optimized parameters by using MATLAB. The proposed antenna is a type of radio antenna with a low profile which is mounted on a flat surface. It consists of a flat rectangular sheet or patch of metal, mounted over a larger sheet of metal called a ground plane. A resonant frequency of 3 GHz is achieved with improved parameters like high return loss, Low VSWR, High directivity & gain, High efficiency. So the proposed antenna can be suitable for the radio astronomy & space research applications.

Abstract

Effective planning of instruction enables the teacher to set out different strategies that can make both teachers and students achieve stated objectives. Teachers are expected to put a lot of effort into planning their instruction, and with the emergence of different technologies (hardware/software), planning can be done with considerable ease. These technologies such as computers, mobile phones, tablets, Personal Digital Assistants (PDAs) and so on create a platform for teachers to explore, gather facts, sort, edit and re-arrange information about a topic before teaching it. Therefore, in this study, pre-service social studies teachers were trained on how to plan instruction using the Mobiles, this was done using a Mobile Learning Lesson Plan (MLLP) template, the influence of age on how pre-service teachers plan instructions using mobiles was also examined. The template is a blueprint of what is to be taught using the mobile phone, it enables teachers to organise, plan, design, and evaluate the lesson effectively. The results show that after the training, the pre-service social studies teachers were able to acquire requisite skills to plan instruction using mobile phones. Also, age does not significantly influence on the ability of pre-service social studies teachers to plan instruction using mobiles.

Abstract

In this paper, an optimization method based on adaptive Neuro-Fuzzy inference system (ANFIS) for determining the parameters used in the design of a coplanar capacitive coupled probe fed rectangular microstrip antenna. The antenna was analyzed in the 2-10GHz range to demonstrate universal working of the proposed model. Here, an expert knowledge of fuzzy inference system (FIS) and the learning capability of artificial neural network (ANN) have been embedded (ANFIS). By calculating and optimizing the patch dimensions of a rectangular microstrip antenna with air gap, this paper shows that ANFIS produces good results that are in agreement with the mathematical analysis of the design parameters of antenna. Of the parameters considered for optimization, the error difference (average) between the proposed model and the calculated data is 0.21% for L, 0.41% for W, and 0.2% for air gap which are less than 0.5% and acceptably low.
