Abstract

Microstrip antenna has been designed and applied to many practical scenarios for wireless communications. To meet the increasing requirements of wireless communication and quality of service, array antenna design deserves studying and analyzing. A novel design of 2.45-GHz microstrip array antenna has been proposed in the paper. The novel array antenna is composed by a planar layout of elements, coaxial feeders and circular feed points. The array antenna is designed to satisfy practical requirements, including frequency channel, voltage standing wave ratio, impedance matching, and signal loss rate. A memetic of genetic algorithm and the quasi-Newton method is proposed to effectively solve the design model. Numerical simulations are performed by the five optimization methods and two array sizes. The results show that the proposed design is able to produce qualified microstrip array antenna for usage. The proposed memetic method is more effective than the other four methods. The microstrip array antenna will be useful for practical wireless communication systems.

Summary

INTRODUCTION

Internet of things (IoT) enlarges the concept of Internet. It is a network of combined by different areas, such as manufacturing factionaries, energy management systems, data collection devices, wireless communications, etc [1]–[3]. Microstrip antenna has many advantages such as small volume size, light weight, easy to conformal with carriers [10] It has been widely used in broadband from 100 MHz to 50GHz such as remote sensing, wireless communication, and radar systems. X. Zhang et al.: Design of Microstrip Array Antenna and Its Optimization by a Memetic Method eligible performance. The optimization of this paper concerns the length, width and location of the feed network Optimizing these parameters is useful to reduce cost for manufacturing antennas and assure high QoS for users. (1) The microstrip array antenna is modeled as an optimization problem with practical constraints.
