Performance Limits of Optical Rectennas
ABSTRACT
Optical rectennas are antenna-coupled diode rectifiers that receive and convert opticalfrequency electromagnetic radiation into DC output. Because classical rectennas working at microwave frequencies can achieve very high Continue reading
Characterization of Alternative Mounting of Vehicular Antenna Systems near Real Grounds
ABSTRACT
Vehicular antenna systems for jamming and communications are frequently mounted on either the roof or rear bumper of the vehicle. While this facilitates easier mounting and maintenance of the antenna systems, it reduces the Continue reading
Microstrip Patch Antennas for Broadband Indoor Wireless Systems
The advantages of microstrip antennas have made them a perfect candidate for use in the wireless local area network (WLAN) applications. Though bound by certain disadvantages, microstrip patch antennas can be tailored so they can be used in Continue reading
Tuneable DVB-H Antenna in a Small Handheld Device
Digital Video Broadcasting for Handheld devices (DVB-H) is a feature that will be introduced to the consumers during 2006. With DVB-H it will be possible to watch TV with Continue reading
Design and Installation of Outdoor TV Antenna
Digital television (DTV) transition June 12, 2009 motivated me to review our outdoor TV antenna and undertake an upgrade program during the fall of 2008. We live in a rural area able to Continue reading
Design of an Antenna for a Wireless Sensor Network for Trains
An antenna for a wireless sensor network for trains is designed and built. The network will monitor temperature and vibrations of the wheel bearings on the train wagons. Doing this will allow for an earlier detection of damaged wheels, which will ease planning of maintenance and reduce Continue reading
An Adaptive Nulling Antenna for Military Satellite Communications
Using adaptive nulling, an antenna system can reconfigure the receive antenna to produce nulls at the locations of any interference sources. Typically, two generic types of adaptive Continue reading
Mobile Digital TV (DVB-H/SH) and 2nd Generation DVB Systems
The purpose of this laboratory exercise is to obtain overview of the block structure of encoder/decoder and modulator/demodulator in systems Continue reading
The Design Process of a Rectangular Microstrip Antenna
The primarily factors concerning the choice and design of this project are pedagogical in nature. In this study, the classic approach to antenna design is followed through its Continue reading
DVB-H: Digital Broadcast Services to Handheld Devices
This paper gives a brief review of the new Digital Video Broadcasting—Handheld (DVB-H) standard. This is based on the earlier standard DVB-T, which is used for terrestrial Continue reading
