slotted waveguide antenna
slotted waveguide antennaStanding wave ratio - Wikipedia ; WebIn radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide.Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave's amplitude at an antinode … Standing wave ratio - Wikipedia ; WebIn radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide.Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave's amplitude at an antinode … Antennas: Cavity-Backed Slot Antennas - Antenna Theory ; WebThe exciting monopole antenna is shown in green. Figure 1. Cavity-backed slot antenna. I'll give some experimental results for this antenna. Let the depth of the cavity C=91mm, the length be A=87mm and the height B=36mm. The height of the monopole antenna will be 29.5mm, so that the monopole is a quarter-wavelength long at 2.55 GHz.
