Polarization Reconfigurable Active Antenna
Active antennas (AAs) are a class of radiation system that integrates an antenna and backing active circuits which results in considerable reduction in complexity of the matching networks and filters [1]. This is done by carefully designing the radiating element to provide proper load for active elements. Hummer and Chang have investigated active antenna elements using a microstrip patch antenn...
متن کاملActive Antenna Amplifier
Today’s wireless communication world revolutionized organizations who are well advanced (& advancing) in design of full fledged compact high gain noise active antenna. This antenna revolution persuaded us to design an active antenna amplifier. This radio p paved way for us. This project paper describes our verification of active antenna to the pract We thank our supervisor, Professor Göran othe...
متن کاملHybrid optical antenna with high directivity gain.
Coupling of a far-field optical mode to electronic states of a quantum absorber or emitter is a crucial process in many applications, including infrared sensors, single molecule spectroscopy, and quantum metrology. In particular, achieving high quantum efficiency for a system with a deep subwavelength quantum absorber/emitter has remained desirable. In this Letter, a hybrid optical antenna base...
متن کاملAccurate Determination of Antenna Directivity
The derivation of a formula for accurate estimation of the total radiated power from a transmitting antenna for which the radiated power density is known in a finite number of points on the far-field sphere is presented. The main application of the formula is determination of directivity from power-pattern measurements. The derivation is based on the theory of spherical wave expansion of electr...
