ABSTRACT In the new era, the researches on the antenna use are achieved better thought and good enhancement in different features. A microstrip patch antenna by a single layer substrate structure is designed in this manuscript. The dielectric substrate layer has a height of 1.6mm. Thus the diverse parameters like gain, directivity, return loss and VSWR are examined for a single layer construction of dielectric substrate. The aerial is designed for the resonant frequency of 2.4GHz. The dielectric substrate material employed for the aerial design is FR4 (Flame Retardant-4) having a permittivity of 4.4. The designed aerial has frequency band that can be used for WLAN applications. Microstrip line feeding method is employed to energize the antenna. The planned aerial is optimized using CST microwave studio. KEYWORDS: Microstrip, Microwave Frequencies & Antenna
INTRODUCTION A device which is used for radiating and receiving EM waves is named as Antenna. It might be either the type of transmitting or receiving and the same be perform as a both. The significant characteristics of an aerial are to focus and form the emitted power in space. In the current communiqué situation, microwave frequencies are employed for

effective transmission and reception. The frequency range for the microwave is from 1GHz to 300GHz [1]. The fast growth of microstrip aerial technology has begun in the late 1970s. But in the early 1980s the elements of basic microstrip aerial and arrays were developed quietly by design and modeling and researchers were paid their attention to enhance the parameters of the antenna. Microstrip Patch Antenna (MPA) is one among the various types of microwave antennas. Nowadays the role of microstrip aerial in modern communications and radio-Electronic systems has become vast. The microstrip patch antenna is employed in much broad class of applications owing to several benefits of these structures. The researcher might choose the material with maximum electrical permeability such that it will lessen the stray field of microstrip lines and its geometrical dimensions. Although it posses many more benefits but it suffers from narrow bandwidth. Thus to attain broader bandwidth performance the multi layer microstrip patch antenna structure can be used [2]. Microstrip aerial contains a metal conducting patch on the top side and it can be carved with a thin grounded dielectric surface called substrate. Antennas which are employed for these applications should be of small shape, less weight, small size. With the help of Microstrip antennas, all these necessities are defeated. Microstrip antennas are employed in a wide variety of use [1], but owing to its narrow impedance bandwidth limit happens. The microstrip aerial usually contains a radiating element (patch), an intermediate dielectric layer (Substrate), and a ground [5].
