In this study, a size-reduced Log Periodic Dipole Antenna (LPDA) with second order semi-circle iteration is presented. Second order semi-circles are added to the dipole arms, which results in lateral size reduction of 23% ...

This study describes about an omnidirectional antenna for satellite communication applications possessing dual circular polarization at almost over the full azimuth plane and wide elevation plane. The antenna does not use ...

Specific Absorption Rate (SAR) analysis is a vital part of compliance tests for commercial mobile phones performed in accordance with the set of comprehensive standardized practices provided by authoritative bodies. ...

Classification of aircraft targets from scattered electromagnetic waves is a challenging application, which suffers from aspect angle dependency. In order to eliminate the adverse effects of aspect angle, various strategies ...

In this paper, the design of omnidirectional and circularly polarized antennas, which can be used in satellite communication, is explained. These antennas consist of circular slotted array placed symmetrically on a cylindrical ...

This study describes about Ku-band antennas with circular polarization in hemispherical radiation pattern for telemetry and telecommand applications of satellite communication. The first section of antenna contains a septum ...

In this study, an implementation of the metamaterial structure is used in a waveguide directional coupler. For this purpose, a four-hole waveguide directional coupler in X-band is designed. Then, the block of dielectric-resonator ...

This paper presents a radar target classification method using high-resolution Min-Norm (minimum norm) technique to discriminate targets in a selected target database. The method is convenient for the targets at the resonance ...

This paper aims at the development of a fast and sufficiently aspect- independent identification method with the processing of wideband scattered signals from radar targets. In the given method, estimation of signal ...

In this paper, an active noise cancellation system to decrease the motor noise arriving to car driver is proposed. This system can be considered as a feedforward control system since it enables taking motor noise as the ...
