broadband antenna การใช้

• As a broadband antenna, the T2FD will normally display a reasonably low SWR does not mean high antenna efficiency.
• Along with his contributions to higher education, Lonnie is also a founder of Broadband Antenna Tracking Systems ( BATS ).
• It is distinguished from broadband antennas, where the passband is large, but the antenna gain and / or radiation pattern need not stay the same over the passband.
• Since LOFAR operates in the 120-240 MHz range, some of the sensors on the Northern Cross Radio Telescope, optimized for 408 MHz, will have to be replaced with broadband antennas.
• In the 1950s and 60s M . S . Neiman proposed the new principle for broadband antennas free from the reflection phenomena and called " antennas of smooth radiation ", and also the new method of calculating the power and radiation resistance of metallic antennas based on the calculation of emission of electrons moving in metal.
• The "'Robinson Barnes HF Broadband Antenna "'was conceptualised and developed in the early 1990s by Graham Robinson and John Barnes and has become a widely used design for commercial and military HF base stations, where ground space is limited, yet a full 4 octave bandwidth ( 2-30 MHz ) is required.
