    The objective of this article is to provide a comprehensive and unified description of the authors' work on the development of wrapped microstrip antennas for laptop applications. The first contribution is the introduction of quasi-omnidirectional wrapped-microstrip antenna elements to be integrated into the display rim of laptops. Single- and dual-band antennas are presented to demonstrate the ca... View full abstract»

    Modern small satellites (MSS) are revolutionizing the space industry. They can drastically reduce the mission cost, and can make access to space more affordable. The relationship between a modern small satellite and a ldquoconventionalrdquo large satellite is similar to that between a modern compact laptop and a ldquoconventionalrdquo work-station computer. This paper gives an overview of antenna ... View full abstract»

    Fundamental physical limitations restrict an antenna's performance based on its electrical size. These fundamental limits are of the utmost importance, since the minimum size needed to achieve a particular figure of merit can be determined from them. In this paper, the physical limitations of antennas are reviewed in general, with particular emphasis on impedance matching as it relates to ultra-wi... View full abstract»

    A new dual-frequency dual-polarized array antenna for airborne applications is presented in this paper. Two planar arrays with thin substrates (R/T Duroid 5880 substrate, with epsivr = 2.2 and a thickness of 0.13 mm) are integrated to provide simultaneous operation at S band (3 GHz) and X band (10 GHz). Each 3 GHz antenna element is a large rectangular ring-resonator antenna, and has a ... View full abstract»

  • Visualization of Negative Refraction in Chiral Nihility Media

    Chiral nihility media are known to produce a backward wave as one of their two polarizations, yielding negative refraction at the interface of the chiral nihility medium and free space. In this paper, the analysis of chiral nihility effects is illustrated by showing the propagation of a Gaussian beam, both reflected and refracted from an air-chiral interface, and through layered chiral nihility me...

  • Reflector Antenna Analysis Using the Complex Equivalent Length Concept: Reciprocity and Coupling Between Feeds

    Publication Year: 2009 , Page(s): 88 - 96
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (3557 KB) |  | HTML iconHTML  

    This work presents a procedure for analyzing multiply fed reflector antennas in both transmission and reception modes, by using the reflector antenna complex equivalent length (RA-CEL) concept. The RA-CEL is derived by combining the feed element complex equivalent length (FE-CEL) method with an equivalent current (EC) model on the reflector surface. This formulation, in terms of both electric and ... View full abstract»

  • Who Was James Clerk Maxwell and What Was and Is His Electromagnetic Theory?

    The electromagnetics community makes profuse utilization of Maxwell's equations, his theory, and their applications. It is arguable that very few of us have clear ideas about what exactly Maxwell did and what kind of scientist he was. In fact, he developed many of the fundamental ideas in electrical engineering, and provided mathematical language for their exposition. His contributions to other br... View full abstract»

    I would like to keep this column short this month, since, as I write this, the lazy days of August are upon us, and many of our colleagues are on holiday for the month (we in the USA need to learn how to holiday like so many of our colleagues around the world!). Another way to put it is that I want to finish this column so I can go swimming with Hannah and Katie. View full abstract»
