Under the project IntLiIon, we are investigating a wireless data transmission alternative for the Battery Management System of electrical and hybrid vehicles. In our previous work [1], we introduced the testbed and battery emulator employed for the first radio channel measurements. In this work, we present an enhanced version of this testbed. The connection method between antenna, cable, and ba...

GOSALIA, KEYOOR. Novel Compact Antennas for Biomedical Implants and Wireless Applications. (Under the direction of Dr. Gianluca Lazzi.) Novel design methodologies and implementation techniques for antennas with an extremely small form factor (kr ¿ 1; k is the wavenumber and r is the radius of enclosing spherical volume) are presented. These size reduction techniques are applied to design antenn...

Various wideband antennas have been interesting subjects in antenna designs and have found important applications in military and civilian systems. For examples, the super-wideband (SWB) antenna is a key component of electronic counterwork equipment in the information warfare; while the ultra-wideband (UWB) antenna is widely used in impulse radar and communication systems. With the development ...

Radial line slot antennas (RLSAs) are well known as high-efficiency planar antennas in high-gain region for the circular polarization [1]. Figure 1 shows the structure of a general RLSA. A radial waveguide is composed of two parallel circular metal plates. An electromagnetic power is fed from the center and excites a slot array on the top plate. To obtain a pencil beam, the radiating elements a...

A novel dual-band design of a finite ground coplanar waveguide (CPW)-fed monopole antenna is presented for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for Microwave Access (WiMAX) applications. The proposed antenna, comprising a rectangular planar patch element embedded with two L shaped slots and stair shape slot in the middle of the patch elemen...

The capacity of a Multiple-Input Multiple-Output (MIMO) system depends on the channel matrix as well as the Signal-to-Noise ratio. A novel dualpolarized planar channel model with one or two scattering rings is used to compare the capacity of different antenna arrays. The correlation between channel matrix elements of the presented channel model and the statistical Kronecker model is also compar...

A circularly polarized (CP) substrate integrated waveguide (SIW) cavity-backed slot antenna is proposed. A slot split ring (SSR) etched on the top metal surface of an SIW resonator is employed to generate the right-handed circularly polarized (RHCP) wave. The proposed antenna is excited directly by a coaxial probe with a proper distance from the symmetric axis of the SSR resonator. A prototype ...

In this paper we discuss the use of electromagnetic band gap (EBG) structures in antenna engineering from a practical point of view. Our aim is to point out the most common mistakes and myths related to design, analysis and application of EBGs in the field of antennas. The paper could be helpful for beginners giving a short course on designing EBGs but also will bring novel findings for experts...

-In the field of wireless communication as the demand for small size systems are increasing, the compact size, low profile, light weight micro strip antennas are attracting the antenna designers attention. But these antennas have some drawbacks like narrow band width, low gain and surface waves. So many researches have proposed different techniques to enhance the band width. Now in present pape...
