The paper presents the method for measuring parameters (gain, antenna factor, impedance and radiation pattern) of small antennas in GTEM cell, which is a novel method and environment for antenna measurements. In order toinvestigate the suitability of GTEM... see more

The radiation of RFID anti-theft gate system based on two parallel coaxial square loop antennas has been analyzed.The system was simulated in FEKO and near electric andmagnetic fields have been calculated. A physical model of thesystem was realized and ne... see more

Electromagnetic (EM) simulation of dual-polarized antennas is necessary for precise initial alignments, calibration and performance predictions of multi-function phased array radar systems. To achieve the required flexibility and scalability, a novel Fini... see more

The growing quality of smartphone-based Global Navigation Satellite Systems (GNSS) chipsets opens a new frontier for scientific research in positioning, navigation and timing applications. The portability and affordability of these instruments could enhan... see more

Wifi technology is a means of obtaining information in a fast way, to strengthen the signal, for that it is required that the functioning antenna emit and receive electromagnetic waves in which contained the information signal. A wide range of antennas ha... see more

The body measurements was made on 20 males of river lobsters (Astacus fluviatilis or Astacus astacus). The lobsters on witch the study was made had an average total length of body of 12.72 cm ±0.19 cm (formed from: 6.07±0.10cm the length of cefa... see more

Estimating the parameters of a geometric propagation model from MIMO channel sounding measurements will be considered, which requires the solution of an inverse problem. Thus, a model of the measured data is derived, which incorporates a model of the meas... see more

The article describes the alternate approach of scientific mission of directional diagram simulation of VHF band radar of P-18 type including beta software MMANA-GAL. All previous radar modernization type P-18 were not associated with the modernization of... see more
