Broadband double-ridged guide horn (DRGH) antennas are extensively used in antenna measurement and electromagnetic compatibility interference testing, especially the 1–18 GHz DRGH which is widely accepted as a standard for this band. Certain deficiencies radiation patterns have been identified corrected by several authors, but use was still limited to frequency The incorporation of absorber mat...
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...
