A single element of the circular patch antenna and 1x2 array elements of circular patch antennas were simulated, fabricated, measured, analyzed, and discussed in this work. Array configuration study is the essence of this research. In order to improve the performances of an antenna, the implementation of array configuration is one of the techniques in designing the patch antenna. Based on the results, it has been verified that an array configuration technique works in enhances and improves the patch antenna performances. This paper also discussed the fabrication process involves and comparison of performances between simulation and measurement. Keywords: Patch, Antenna, Array, Directivity, Gain, Fabrication I. INTRODUCTION In a wireless communication system, an antenna plays an important role in transmitting and receiving radio signals. Without an antenna in the communication system, neither signal transmitted from the base station nor signal received at the mobile terminal will happen. An antenna also is the main component in the ambient radio frequency energy harvesting system. In between the process, there is an electromagnetic field (EMF) generated. This readily free energy can be harvest, useable and store as direct current (DC) voltage. Designing an antenna is the state-of-art in a wireless communication system. In designing an antenna, several points need to be included in the initial state of design. Some of the points are the application of the antenna design. The antenna is designed either to be used in radio broadcasting technology, electromagnetic radiation energy harvesting system, medical or military use. The descriptions and specifications of the antenna arebased on the application of the design. For particular applications of an antenna, there is a specific design that suits its requirement. For example, a directional antenna. Revised Manuscript Received on September 22, 2019. Saidatul Hamidah Abd Hamid, College of Engineering, University Tenaga NasionalPutrajaya, Malaysia Goh Chin Hock, College of Engineering, University Tenaga Nasional Putrajaya, Malaysia Nayla Ferdous, College of Engineering, University Tenaga Nasional Putrajaya, Malaysia This type of antenna is known to have high in directivity and gain that gives the perfect recipes for a transmitter. In wireless power transfer technology, in Radio Frequency Identification (RFID) for example, the RFID reader transmitted the power to the input of RFID transponder (tag) and activated the passive circuitry of the tag [1]. This is an example of the application that requires high directivity and gain performances of an antenna. High performance in directivity and gain are quite difficult to achieve in a single element of an antenna. From previous findings, a single element of patch antenna only can be achieved around 6dBi to 7dBi [2] in directivity. There are several methods and techniques has been discussed by the previous studiesregarding how to optimized or the technique can be implemented to improve the performance of antenna design. In [3], this paper discusses a novel design of a Genetic Algorithm (GA) technique. This method breaks the patch into several small parts and aligned them with minimum overlapped to each other. Others techniques and methods discussed in [4-6] already been discussed in [7] which is the continuity study of this work. In this paper, the objectives are to present the comparison of performances specifically in directivity and gain improves by array configuration technique implementation, between single element and 1x2 arrays element in the form of simulation and fabrication. In this paper also will discussin the perspective of the fabrication of both designs. II. METHODOLOGY A. Design Philosophy 1) Array Configuration Technique In designing the 1x2 array configuration, two identical single circular patch antenna were combined and work as a single antenna. A duplicate of a single element was aligned accordingly with the directivity of a single element, D (θ, ϕ) multiply with the array factor, AF. [8] 2) Feeding Techniques For this specific research study, the power line of the radiation patch by implementing the proximity feeding coupling technique. The advantages of using this type of feeding are less line radiation compared to microstrip feed Verification of Performances Enhancement by Array Configuration Technique in Patch Antenna Design for Energy Harvesting Applications Saidatul Hamidah Abd Hamid, Goh Chin Hock, Nayla Ferdous
