Magnetodielectric Material for VHF Antenna Devices Tunable by a Low DC Magnetic Field
نویسندگان
چکیده
This study presents the performance of a magneto-dielectric material (MDM) specially developed to enable tunability antenna devices operating in VHF band. A current flowing through sample, which creates DC magnetic field inside sample with same symmetry as domains, controls susceptibility variation MDM. By changing magnetization state MDM low 740 A.m-1, 40% can be observed. The at frequencies is also highlighted by microwave measurements for different states.

Giant magnetodielectric effect and magnetic field tunable dielectric resonance in spinel MnZn ferrite
The sensitive response of the dielectric permittivity under the application of magnetic fields in Mn0.60Zn0.40Fe2.12O4+ polycrystalline ferrite is presented. A magnetic field of 3.5 kOe induced a giant magnetodielectric MD= H − 0 / 0 response, of 1800% at f =7 MHz, at room temperature. The ferrite exhibits a large magnetic field-induced frequency response of 180 Hz/Oe. We suggest that this effe...

The emerging field of communications has increased the demand of electronically tunable reflectarray antennas. Substrate material properties play at1 important role in the design of reflectamy antennas. Variable permittivity materials such as liquid crystals and fenoelectrics have received great deal of attention due to their non-linear material properties. A comparative analysis behveen the pr...
متن کاملA Miniaturized Loran H-field Antenna for Handheld Devices
This paper presents Loran signal processing results for a series of successively smaller H‐ field square‐loop antennas input to a preliminary design of low‐noise‐optimized, low‐ frequency ASIC. Antennas as small as 5cm (2‐inches) on a side are able to detect Loran signals both outdoors and indoors, although in some cases significantly attenuated compared to signals from a larger 50cm (20‐inch)...
متن کاملLow Settling Time All Digital DLL For VHF Application
Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...
