Antenna Bandwidths

September 27th Fact-of-the-Day

Different bandwidths can be correctly specified for the same antenna, because antenna bandwidths are stated with respect to a specified antenna characteristic. For example, an antenna may have a wide feed-impedance bandwidth, but a narrow gain bandwidth. A different antenna may have a narrow feed-impedance bandwidth, but a wide gain bandwidth. Any antenna characteristic, such as vertical beam-width, azimuth beam-width, reflected power, radiated-field phase shift, or anything else that is important to a specific application can be the basis for a bandwidth specification. ©2004 Martek, International.
