Manipulation of an antenna's radiation pattern
can be used to avoid noise source, improve security and save energy by better directing signal toward intended direction [1,3].
Electrically small loop antennas are favorable for their simplicity and their radiation pattern
Tenders are invited for 5-D Radiation Pattern
It covers the fundamentals of bioacoustics, including the wave equation, wave propagation, and reflection, refraction, and transmission in the acoustic field, as well as the radiation pattern
of ultrasound transducers, and the acoustical properties of biological tissues; nonlinear acoustics; cavitation, the design of transducers, and the characterization method of the produced acoustic field; and applications in ultrasonic physiotherapy, hyperthermia, shock wave lithotripsy, and drug delivery and gene transfection, as well as applications of high-intensity focused ultrasound.
Moreover, the RFIDs reader antenna radiation pattern
has been obtained by means of the near field probe.
Each of the three sensors is positioned orthogonally inside the antenna housing to transmit/receive a spherical radiation pattern
so all radiation is measured at the antenna's geographical position, regardless of the direction in which it arrives.
Genetic algorithm optimization for radiation pattern
synthesis of linear array of antennas is used in formation of adaptive array pattern.
EC482 enables Ethertronics' Active Steering beam steering technique from a wireless device by monitoring RF link performance, and through a combination of closed loop and predictive algorithms, optimally selects the antenna radiation pattern
that provides the best RF link performance.
The design analysis is performed by using commercial software, which characterizes 3-D structures in order to determine the bandwidth and radiation pattern
of the antenna.
For the horizontally polarized omnidirectional radiation pattern
, the magnetic dipole is an alternative solution.
Compared to [19, 20], the proposed antenna posses a wide bandwidth and stable radiation pattern
, even with its compact size.
The E-plane (phi = 0[degrees]) is a figure-eight radiation pattern
and the ff-plane (phi = 90[degrees]) nearly omni-directional radiation pattern
