In the fields of electromagnetic interference and electromagnetic compatibility, it is important to measure the strength of the electric field originating from electric devices. For this purpose, knowledge of the antenna factor of a receiving antenna is necessary. According to international standards, the accurate measurement of the antenna factor involves the use of calibration test sites char...

ABSTRAKPada studi ini dilakukan analisis penambahan batang metal berbentuk persegi di dalam feed horn piramida antena reflektor parabola untuk meningkatkan performansi gain, beamwidth dan side lobe level. Kebutuhan utama radar maritim adalah memiliki gain yang besar ≥ 27 dB, kecil ≤ 2o, level rendah -30 dB. Oleh karena itu, perlu diajukan teknik desain dengan performasi Hasilnya dapat menjadi 3...

In this paper, a dual-polarized antenna based on substrate-integrated waveguide (SIW) horn and Vivaldi is proposed. The horizontal polarization (HP) achieved by using the H-plane SIW antenna, while vertical (VP) realized typical etched surface of antenna. front aperture, dielectric lens designed to optimize impedance matching enhance directivity. Different feeding structures two polarizations a...

This paper reports narrowband and wideband results derived by propagation modeling at 60 GHz for indoor WLAN applications. A multi-ray model is proposed and verified through a simulation process. The propagation in the site-specific environment can be described using 4-5 rays without reducing the accuracy of the results. RMS delay spread varies with distance from 0.57 ns up to 2.32 ns. Coherenc...
