چکیده
In this paper, a frequency reconfigurable, conformal, durable, optically transparent, and unidirectional antenna design is demonstrated for the first time. design, continuous tuning achieved by integrating varactor diode in folded dipole radiator, which backed water-filled reflector to produce radiation pattern mimicking characteristics of microstrip patch antennas. The radiating component explored manufactured from transparent conductive fabric, has about 72% optical transparency occupies small fraction entire antenna. located underneath radiator. Water contained inside rectangular box made flexible-transparent-hydrophobic polymer, polydimethylsiloxane (PDMS). Both water PDMS are highly moreover, excellent flexibility liquid, thus, exhibits durability against physical deformation. tiny integrated radiator insignificant effect on overall been numerically investigated experimentally validated through measurements. Measurements show 2.38 GHz 2.67 with an average 10-dB return loss bandwidth 170 MHz. Moreover, maintains good front-to-back ratio operating band.

متن کاملAn Electronically Tunable Resonator for Noise Control
Many engineering systems create unwanted noise that can be reduced by the careful application of engineering noise controls. When this noise travels down tubes and pipes, a tuned resonator can be used to muffle noise escaping from the tube. The classical examples are automobile exhaust and ventilation system noise. In these cases where a narrow frequency band of noise exists, a traditional engi...
متن کاملAn Electronically Switchable Leaky Wave Antenna
We report an electronically switchable dielectric leaky wave antenna. The main beam angle can be electronically steered using p-i-n diodes. The diodes are used as switches to control the radiation from two sets of gratings with different periods, thereby switching the main beam angle. Beam steering is achieved at a single fixed frequency; no frequency sweeping is necessary. A microwave prototyp...
