    Abstract
    This paper presents a novel design of a harmonic suppression single-fed dual-circularly polarized microstrip patch antenna for a rectenna system in the future wireless power transmission application. The proposed antenna is capable of receiving both types of circular polarization signal; RHCP and LHCP simultaneously and at the same time it also able to filter the unwanted harmonic signals itself. These characteristics are achieved after introducing a circular slot defected ground structure to an array of nearly-square microstrip patch antenna with an offset inset microstrip feeding line and two open stubs on the feeding line. The proposed antenna is very simple on the single substrate only and this led to a reduction of errors that occurs during the fabrication process. However, the most importantly is the possibility of the polarization mismatch during transmission of signal can be minimized and the use of additional harmonic filter circuit can be eliminated. Thus the rectenna system becomes smaller, cheaper, less complexity and more efficient. The overall structure of the proposed antenna is designed on the top surface of the PCB only, thus it can be interfaced with other circuit such as rectifier or other circuit easily. The Computer Simulation Technology (CST) has been used in the simulation and optimization of the design. Finally, for the verification of the design, the prototype of the proposed antenna is fabricated and measured. From the simulation and measurement results, the proposed antenna can be a good choice in the rectenna system for future wireless power transmission application.
