An experimental validation for millimeter-wave (mm-wave) channel measurement is presented in a reverberation chamber (RC) at 28 GHz band. A 28 GHz channel sounder and a vector network analyzer were used to measure complex channel transfer functions at the specific position of the rotating mode-stirrer in the RC. To demonstrate the experimental validation according to different antenna directions and...
A substrate-integrated-waveguide (SIW) aperture-coupled antenna array is presented at millimeter-wave band. The antenna design is located on the upper part of the substrate fixed with a half size of Samsung Galaxy Note 4. The antenna array has been implemented with the multilayer structure which is realized by stacking three substrates and a copper plate. The simulated results are validated with the...
In recently, mobile communication technology is developing toward the 4th generation communication technology. The LTE (Long Term Evolution) is the leading candidate technology in the 4th generation mobile communication. The LTE technology is combined with the MIMO (Multiple Input Multiple Output) technology and this coupled technology has a high-quality data transfer rate and an expended channel...
According to super minimal electronic product technology development, the illegal usage and theft from domestic of minimized electronic device such as semi-conductor, USB memory chip and etc., has been issued. These devices are frequently used for the illegal purpose such as hidden wiretapping, hidden camera, bomb and threat of terror [1]. Many countries including the United States have been developed...
This paper presents basic design for patch antenna element with fan structure operated at the LTE (Long Term Evolution) UHF band. The proposed antenna based on the PIFA (Planar Inverted-F type Antenna) was considered a meander line structure to satisfy resonance in LTE Band at a small restricted area of 30×24 mm. In order to control directivity of the radiation pattern, a fan-shaped radiator structure...
