The present thesis deals with the electromagnetic modeling, design and practical implementation of a planar antenna for the reception of satellite broadcasting services from user terminals on board automotive platforms. This antenna is intended to address ...
In this letter, a compact single-layer, single-feed, dual-frequency microstrip antenna with a high frequency ratio is proposed. This antenna has a broadside and symmetrical radiation patterns suitable for space-borne applications. The prototype was fabrica ...

This paper presents an innovative switched-beam architecture for a low-cost mobile-terminal antenna, suitable for linear-polarized satellite communications systems. This antenna concept can produce twelve adjacent sector beams that cover the full azimuth f ...
Automatic Vehicle Location (AVL) Systems are being introduced increasingly in many major cities around the world to improve the efficiency of our road-based passenger transport systems. Satellite-based location and communication systems, particularly the G ...
The South Pole Acoustic Test Setup (SPATS) was built to evaluate the acoustic characteristics of the South Pole ice in the 10-100 kHz frequency range, for the purpose of assessing the feasibility of an acoustic neutrino detection array at the South Pole. T ...
Since the dawn of the Space Age, over six thousand satellites have been launched into Earth orbit. The function of determining the orientation of a satellite in orbit, so that it can point its antennas and instruments in the required direction is known as ...
One of the most promising bands for long-range radiocommunications is the Ka-band (25-40 GHz). This is due to the existence of a natural radio transmission window around 30 GHz. Both terrestrial and satellite transmission systems are planned on this freque ...
This Article Addresses the Design and optimization of a small-sized linear electrodynamic actuator, to be inserted below a computer key so as to provide a force feedback to the user. The importance given to the sense of feeling has been growing in differen ...
We present an implementation of our deadlock immunity system, Dimmunix, for mobile phone software. Within Android 2.2 OS, we modified Dalvik VM, the JVM running all the Android applications, to provide platform-wide deadlock immunity. We successfully ran th ...
The worldwide maintenance of the honeybee has major ecological, economic, and political implications. In the present study, electromagnetic waves originating from mobile phones were tested for potential effects on honeybee behavior. Mobile phone handsets w ...
