Lantz Program Chairman The conference theme this year is “Systems and Technology in the ’80’s: Expanding Horizons.” It was selected to continue the theme which began with ITC/USA ’80. The technological advances that have occurred over the past decade have, and continue to have, a profound affect on the nature and applications of telemetry systems. It is felt that the papers and tutorials which make up this year’s conference will provide you with some insight into these “Expanding Horizons.” The technical exhibits compliment the technical sessions. -

Antenna Tips page 1 of 31 Source : http://www.funet.fi/pub/dx/text/antennas/antinfo.txt Antenna Articles Collection of short articles relating to all manners of antennas. These articles are the hard work of Wayne Sarosi KB4YLY (995 Alabama Street, Titusville, FL 32796) SUBJECT: Circular Polarized Antenna There has been a request for a series on 'CP' antennas. The term 'CP' eluded me at first as I was not familar with the abriviated designator for circular polarization. At work, we just use the entire words. I'm going to begin this ten part series with the basics. After researching CP designs with a few engineers and fellow hams, I found that they knew very little about the subject. I also found I didn't know quite as much as I thought I did about circular polarization. So starting at the begining will help all out. First, let's discuss the circular polarized wave. There seems to be conflicting standards used by the world of physics and the IEEE. I found this to be true in four reference manuals including the ARRL Antenna Handbook. At least it's stated right up front but biased according to which text you read. We will follow the IEEE/ARRL standard in the following series for obvious reasons. There are two types of circular polarization; right and left. All of us agree up to this point. According to the ARRL Antenna Handbook, the following statement: 'Polarization Sense is a critical factor, especially in EME work or if the satellite uses a circular polarized antenna. -

One of these, which occupied most of my attention from 1959 to 1966, was concerned primarily with basic analysis and synthesis techniques pertinent to antenna arrays, which, for the most part, is an applied mathematics problem. The goals then were to produce a particular class of radiation patterns, to reduce sidelobe levels, to maximize the directivity, and to synthesize an array with a relatively broad frequency band, or to achieve some combinations of these. Isotropic elements were mostly used for the sole purpose of developing general mathematical models, which should not be limited to any particular kind of antennas or frequency bands. -

Traveling Wave Antennas
Traveling Wave Antennas Antennas with open-ended wires where the current must go to zero (dipoles, monopoles, etc.) can be characterized as standing wave antennas or resonant antennas. The current on these antennas can be written as a sum of waves traveling in opposite directions (waves which travel toward the end of the wire and are reflected in the opposite direction). For example, the current on a dipole of length l is given by The current on the upper arm of the dipole can be written as ÆÈÇ ÆÈÇ +z directed !z directed wave wave Traveling wave antennas are characterized by matched terminations (not open circuits) so that the current is defined in terms of waves traveling in only one direction (a complex exponential as opposed to a sine or cosine). A traveling wave antenna can be formed by a single wire transmission line (single wire over ground) which is terminated with a matched load (no reflection). Typically, the length of the transmission line is several wavelengths. The antenna shown above is commonly called a Beverage or wave antenna. This antenna can be analyzed as a rectangular loop, according to image theory. However, the effects of an imperfect ground may be significant and can be included using the reflection coefficient approach. If l >> h, the contribution to the far fields due to the vertical conductors is small and is typically neglected. Note that the antenna does not radiate efficiently if the height h is small relative to wavelength. In an alternative technique of analyzing this antenna, the far field produced by a long isolated wire of length l can be determined and the overall far field found using the 2 element array factor. -
Design Methodology for Wideband Electrically Small Antennas (ESA) Based on the Theory of Characteristic Modes (CM)
Design Methodology for Wideband Electrically Small Antennas (ESA) Based on the Theory of Characteristic Modes (CM) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Khaled A. Obeidat, MSEE, BSEE Graduate Program in Electrical and Computer Engineering The Ohio State University 2010 Dissertation Committee: Professor Roberto G. Rojas, Advisor Professor Robert J. Garbacz Professor Fernando L. Teixeira Copyright by Khaled A. Obeidat 2010 ABSTRACT Emerging broadband applications with market pressures for miniaturized communication devices have encouraged the use of electrically small antennas (ESA) and highly integrated RF circuitry for high volume low cost mobile devices. This research work focuses on developing a novel scheme to design wideband electrical small antennas that incorporates active and passive loading as well as passive matching networks. Several antennas designed using the proposed design technique and built and measured to assess their performance and to validate the design methodology. Previously, the theory of Characteristic Modes (CM) has been used mostly for antennas analysis. However; in this chapter a design procedure is proposed for designing wide band (both the input impedance bandwidth and the far field pattern bandwidth) electrically small to mid size antennas using the CM in conjunction with the theory of matching networks developed by Carlin [7]. In order to increase the antenna gain, the antenna input impedance mismatch loss needs to be minimized by carefully exciting the antenna either at one port or at multiple ports and/or load the antenna at different ports along the antenna body such that the Q factor in the desired frequency range is suitable for wideband matching network design. -

PCN 144 000062 80 DEPARTMENT OF THE NAVY Headquarters United States Marine Corps Washington, D.C. 20380-1775 1 June 1999 FOREWORD Communications and information systems (CIS) support collect- ing, processing, and exchanging information. CIS automate routine functions, freeing commanders and staffs to focus on the aspects of command and control that require experience, judg- ment, and intuition. Personnel who install, operate, and maintain CIS play a key role in the command and control of the Marine air- ground task force (MAGTF). It is an understatement to say that the success of the MAGTF in the modern battlespace depends on the effective employment of CIS. One of the most important networks of the MAGTF CIS architec- ture is single-channel radio (SCR). SCR is the principal means of communications support for maneuver units. SCR communica- tions equipment is easy to operate, and networks are easily established, rapidly reconfigured, and, most importantly, easily maintained on the move.
