Abstract
Improved Q factor for stripline and microstrip filters can be realized by increasing the thickness of conductive paths. Increased conductive paths in a stripline and microstrip filter can be realized by forming slots (20) in a block of dielectric material (12) which permit an increased thickness of transmission path thereby improving the Q factor of the material by reducing at least resistive losses.
