Waveguide antenna

The slot waveguide antenna is fabricated and measured to validate the proposed design. The measured results show that the monopulse system can achieve an impedance bandwidth of % (– GHz) in the Ka-band at the centre frequency of 35 GHz. The sum-pattern maximum gain and radiation efficiency are dBic and 75% at 35 GHz, and the. Waveguide *All M.E.C. products are passive microwave devices and can easily be customized for specific frequency, power, configuration, and environment. Decades of experience designing, fabricating and testing passive microwave antenna and components ensures that you will receive a product of outstanding quality. Antenna gain is the ability of the antenna to radiate more or less in any direction compared to a theoretical antenna. If an antenna could be made as a perfect sphere, it would radiate equally in all directions. As a general rule, circular waveguide has a loss of about dB/ft at 13 GHz, while elliptical waveguide has a loss of about 0.
