The discussion revolves around the relationship between relative permittivity and the bandwidth of antennas, exploring how variations in permittivity might influence bandwidth characteristics. Participants reference different types of antennas and their surrounding materials, raising questions about the implications of these factors on performance.
Participants express differing views on the connection between relative permittivity and bandwidth, with no consensus reached. Some believe there is a general relationship, while others question its validity based on their experiences and knowledge.
Participants exhibit uncertainty regarding the definitions of permittivity and permeability, and there are references to specific antenna configurations that may influence the discussion. The relationship remains unresolved, with varying interpretations of existing literature.
Regular metal antennas (dipoles, monopoles, loops, folded dipoles, horns) are surrounded by air or vacuum. What relative permeability are you referring to?qnach said:What is the connection of relative permittivity and bandwidth of an antenna?
Higher relative permittivity resulted in high wider bandwidth?

Was it for a particular geometry of antenna? Like maybe a folded dipole, or some other configuration where the antenna metal comes close to itself?qnach said:I saw this connection in a paper. But in a antenna class I heard the contrary. It seems everyone know this connection.

It looks like you will need to find and post some links to the papers that everybody is publishing on the subject...qnach said:I think it is a general relationship, and everybody know.
