Abstract :
Two novel planar fed printed dipoles have been demonstrated. One utilizes a CPW to slotline transition and the other an original microstrip to slotline transition. In both cases, proper selection of dielectric constant and thickness for the substrate relative to the wavelength is required to ensure proper antenna performance. The radiation patterns and return loss measurements for these antennas revealed that excellent performance can be achieved by both feeding methods. These designs are straightforward to implement in MMIC and MIC circuits and allow for easy insertion of printed antennas for a multitude of applications.<>
