WebThe input impedance of the Rhombic antenna lies between 650 to 700Ω. The directivity of the Rhombic antenna varies between 20 and 90. The power gain lies between 15 and 60 after taking power loss in terminating resistance into account. It is a very useful antenna for transmission and reception in the HF band. It is easy and cheap to erect. WebMar 24, 2024 · Understanding Radar Antenna Beams, Half Power Beam Width (HPBW) and First Null Beam Width (FNBW) Everyone knows what an antenna is when they see one …

WebDec 17, 2016 · Present article proposes a closed-form design expression of First Null Beam Width (FNBW) of a broadside linear antenna array with Taylor distribution. The design expression is formulated by observing the variation of FNBW with respect to the number of elements, inter-element spacing and side-lobe ratio. Effectiveness of the proposed … WebSimply, FNBW is the angular separation, quoted away from the main beam, which is drawn between the null points of radiation pattern, on its major lobe.
