Uni-Directional CPW-Fed Slot Antennas Using Loading Metallic Strips and a Widened Tuning Stub on Modified-Shape Reflectors
Uni-directional CPW-fed Slot Antennas Using Loading Metallic Strips and a Widened Tuning Stub on Modified-Shape Reflectors Sarawuth Chaimool 1, Prayoot Akkaraekthalin 1, and Monai Krairiksh 2 1 Department of Electrical Engineering, Faculty of Engineering, King Mongkut’s Institute of Technology North Bangkok, Bangkok 10800, Thailand, E-mail: [email protected] 2 Faculty of Engineering and Research Center for Communications and Information Technology King Mongkut’s Institute of Technology Ladkrabang, Bangkok 10520, Thailand Abstract We have observed that the size and shape of the conducting reflector of CPW-fed slot antennas using loading metallic strips and a widened tuning stub have significant impact on the antenna impedance matching and radiation pattern. By shaping the reflecting conductor, noticeable enhancements in both radiation pattern which provides uni-directional all frequency operating band and characteristic im- pedance matching are achieved. 1. INTRODUCTION The technique for reducing back radiation of the CPW-fed slot anten- nas is of interest due to it is possible place some type of conducting reflector behind the slot in order to reduce backside radiation and increase the gain. Among the several popular reducing back radiation techniques, a flat conducting reflector is easy in fabrication and most popular method for the electrically thick substrate CPW-fed slot antenna [1]. However, the presence of the flat conducting reflector Fig. 1: CPW-fed slot antennas using loading metallic strips and a widened may cause problems such as power leakage in the parallel-plate tuning stub (a) antenna element, above (b) flat reflector, (c) corner reflector, Λ modes which degrade impedance bandwidth and radiation pattern.

Lecture 28 Different Types of Antennas–Heuristics
Lecture 28 Different Types of Antennas{Heuristics 28.1 Types of Antennas There are different types of antennas for different applications [128]. We will discuss their functions heuristically in the following discussions. 28.1.1 Resonance Tunneling in Antenna A simple antenna like a short dipole behaves like a Hertzian dipole with an effective length. A short dipole has an input impedance resembling that of a capacitor. Hence, it is difficult to drive current into the antenna unless other elements are added. Hertz used two metallic spheres to increase the current flow. When a large current flows on the stem of the Hertzian dipole, the stem starts to act like inductor. Thus, the end cap capacitances and the stem inductance together can act like a resonator enhancing the current flow on the antenna. Some antennas are deliberately built to resonate with its structure to enhance its radiation. A half-wave dipole is such an antenna as shown in Figure 28.1 [124]. One can think that these antennas are using resonance tunneling to enhance their radiation efficiencies. A half-wave dipole can also be thought of as a flared open transmission line in order to make it radiate. It can be gradually morphed from a quarter-wavelength transmission line as shown in Figure 28.1. A transmission is a poor radiator, because the electromagnetic energy is trapped between two pieces of metal. But a flared transmission line can radiate its field to free space. The dipole antenna, though a simple device, has been extensively studied by King [129]. He has reputed to have produced over 100 PhD students studying the dipole antenna.

Slot antennas are very commonly used on commercial and military aircraft because they can be easily molded into the structure of the aircraft. Also used in cell phone towers at microwave frequencies •What frequencies are slot antennas commonly used at? Typically, slot antennas are used at 300 Mhz and above.

Vandenbosch, G. Caille, J. Herault, J.Freeze, M.Thiel, S. Sevskiy, A. Pippi , M. Lanne, L.Petersson, P. Persson, and G. Gerini Abstract The deliverable D6 represents a first step for structuring the research on conformal antennas, dispersed in several European universities and industrial Research centres. The inventory of the on-going research covers both the software and hardware activities, and it will help in defining most useful antenna architectures & geometries and in organizing students/Ph.D exchange between various European academies and companies. When designing conformal antennas it is convenient to use specialized programs for specific conformal geometries that are fast and often more accurate than general electromagnetic solvers since they explicitly take into account the antenna geometry. Therefore, a detailed description of the developed software packages for analysing conformal antennas is presented. The developed arrays covers most-interesting types of conformal antennas, and they will be used as conformal benchmarking structures to judge antenna software tools on its performance. This will help in selecting proper software for some particular problem, and in integration of different software tools.
