  • Improvement of RF Wireless Power Transmission Using a Circularly Polarized Retrodirective Antenna Array with EBG Structures
    applied sciences Article Improvement of RF Wireless Power Transmission Using a Circularly Polarized Retrodirective Antenna Array with EBG Structures Son Trinh-Van, Jong Min Lee, Youngoo Yang, Kang-Yoon Lee and Keum Cheol Hwang * ID School of Electronic and Electrical Engineering, Sungkyunkwan University, Suwon 440-746, Korea; [email protected] (S.T.-V.); [email protected] (J.M.L.); [email protected] (Y.Y.); [email protected] (K.-Y.L.) * Correspondence: [email protected]; Tel.: +82-31-290-7978 Received: 14 December 2017; Accepted: 22 February 2018; Published: 26 February 2018 Abstract: This paper presents the performance improvement of a circularly polarized (CP) retrodirective array (RDA) through the suppression of mutual coupling effects. The RDA is designed based on CP Koch-shaped patch antenna elements with an inter-element spacing as small as 0.4l for a compact size (l is the wavelength in free space at the designed frequency of 5.2 GHz). Electromagnetic band gap (EBG) structures are applied to reduce the mutual coupling between the antenna elements, thus improving the circular polarization characteristic of the RDA. Two CP RDAs with EBGs, in the case 5 × 5 and 10 × 10 arrays, are used as wireless power transmitters to transmit a total power of 50 W. A receiver is located at a distance of 1 m away from the transmitter to harvest the transmitted power. At the broadside direction, the simulated results demonstrate that the received powers are improved by approximately 11.32% and 12.45% when using the 5 × 5 and 10 × 10 CP RDAs with the EBGs, respectively, as the transmitters.

  • Reflector Antennas
    Reflector Antennas A reflector antenna utilizes some sort of reflecting (conducting) surface to increase the gain of the antenna. A typical reflector antenna couples a small feed antenna with a reflecting surface that is large relative to wavelength. Reflector antennas can achieve very high gains and are commonly used in such applications as long distance communications, radioastronomy and high-resolution radar. Corner Reflector The corner reflector antenna shown below utilizes a reflector formed by two plates (each plate area = l × h) connected at an included angle ". The feed antenna, located within the included angle, can be one of many antennas although simple dipoles are the most commonly used. The most commonly used included angle " for corner reflectors is o 90 . The electrical size of the aperture (Da) for the corner reflector antenna is typically between one and two wavelengths. Given a linear dipole as the feed element of a 90o corner reflector antenna, the far field of this antenna can be approximated using image theory. If the two plates of the reflector are electrically large, they can be approximated by infinite plates. This allows the use of image theory in the determination of the antenna far field. For analysis purposes, the current on the feed element is assumed to be z-directed. The image element #2 represents the image of the feed element (#1) to plate #1. Together, elements #1 and #2 satisfy the electric field boundary condition on plate #1. Similarly, image element #3 represents the image of the feed element to plate #2. In order for image element #2 to satisfy the electric field boundary condition on plate #2, an additional image element (#4) is required.

  • Design of Circular Array with Yagi-Uda Corner Reflector Antenna
    Progress In Electromagnetics Research M, Vol. 94, 51–59, 2020 Design of Circular Array with Yagi-Uda Corner Reflector Antenna Elements and Camera Trap Image Collector Application Suad Basbug* Abstract—A six-element circular antenna array with Yagi-Uda corner reflector elements is proposed in order to achieve 360◦ beam-steering capability, high gain, and cost-effective design objectives. The array element is mainly composed by a Yagi-Uda antenna, a corner reflector, and a Wilkinson balun. For steering the main beam, instead of classical RF switching techniques, a virtual switching technique is offered. For this aim, each antenna element is connected to an affordable RF transceiver managed by a microcontroller. A USB hub is also used so that a computer operates all microcontrollers as peripheral devices. In this way, the switching operation can be performed in the software level. Furthermore, if every transceiver in the separate chain is set to a different frequency channel, a simultaneous communication is also possible with the help of the multithreading facility of the computer. In order to show the antenna array performance, the main antenna characteristics and test results are given. As a proof of concept, a wireless image collector scenario is also realized for a camera trap application. The results show that the circular antenna array design and switching technique work successfully. 1. INTRODUCTION A dipole antenna is a very simple and effective solution for the wireless communications since it radiates equally in all directions in the azimuth plane. However, modern communication systems frequently need to concentrate the electromagnetic waves into certain directions in this plane, because the main beam steering and high directivity are often key factors for the long-distance communications and interference avoidance.

Types of antenna like horn antenna, helical antenna, Yagi-Uda array antenna, Log periodic antenna, reflector antennas, lens antenna are discussed. This unit also deals with the characteristics of each type of antenna and antenna application. 5.2 Objective To learn different types of antennas To learn the procedure to calculate different parameters of antennas. 5.3 Helical antenna A helical antenna is a specialized antenna that emits and responds to electromagnetic fields with rotating (circular)polarization. These antennas are commonly used at earth-based stations in satellite communications systems. This type of antenna is designed for use with an unbalanced feed line such as coaxial cable. The center conductor of the cable is connected to the helical element, and the shield of the cable is connected to the reflector. To the casual observer, a helical antenna appears as one or more "springs" or helixes mounted against a flat reflecting screen. The length of the helical element is one wavelength or greater. The reflector is a circular or square metal mesh or sheet whose cross dimension (diameter or edge) measures at least 3/4 wavelength. The helical element has a radius of 1/8 to ¼ wavelength, and a pitch of 1/4 to 1/2 wavelength.
