Abstract

Microstrip array antennae are the ultimate solution for a variety of system applications, including air traffic control and collision avoidance radar. A microstrip antenna array is used since it is easy to design and fabricate. It has small size, light weight and high gain. Microstrip antenna array design is an important area of research in radar system that can meet the subject requirement. Microstrip antennae are used in a variety of wireless applications, including radars, wireless sensor networks, cellular phones and in medical applications. The paper proposes a design of different microstrip array antennae for weather radar system. Corporate feeding technique is incorporated for the design of an array. The proposed antennae resonate at 5.8 GHz.

Description

Microstrip antenna array is currently one of the fastest emerging segments in the telecommunication industry and has become a promising medium in the field of telecommunication in the future. Recent growth in civilian radar-based sensors and communication systems has drawn increasing interest in utilizing antenna array technology for commercial applications (Daiki et al., 2012). Enhancing antenna directivity in order to improve long-range communication has been a subject of extensive research since the time of Marconi's paper (Balanis, 2005). Microstrip antennae (also known as patch antenna) (Molz, 1964) are presently one of the high bandwidth antennae in telecommunication systems. Research has been carried out in the recent past to improve the performance and efficiency of these patch antennae. Rapid development in patch antennae started in the 1970s and by the end of the 1980s, the idea of using microstrip array antenna in wireless communication was well established (Pozar and Schaubert, 1995). The lightweight, reduced size, phase steering ability, ease of installation, low cost and possibility of integration of patch antennae make this antennae the best choice of researchers and manufacturers (Wen-Qin, 2016). The radiation pattern is usually very broad in single element antenna. So the directivity is effectively very low. By enlarging the size of the element, the directivity can be improved. The alternative way is to assemble the antenna elements in a geometrical configuration, which is known as array. The individual elements forming the array are identical and they can be of any form, as reported by Pozar (1995). Microstrip antenna arrays are classified into three types: linear array, planar array and scanned array. The paper proposes planar array antennae.
