Effect of the Different Shapes: Aperture Coupled Microstrip Slot Antenna 105 Microstrip Feed Line Feed substrate dielectric constant should be in the range of 2 to 10.A thinner feed substrate results in less spurious radiation from feed lines, but higher loss. A compromise of 0.01 λ to 0.02 λ is usually good.

EFFECT OF SQUARE SLOTS ON UNIPOLAR MICROSTRIP ANTENNAS FOR ... Abstract. A simple square slots loaded unipolar rectangular microstrip antenna is proposed for quad-band operation. The proposed antenna is simple in its geometry and has been constructed from conventional rectangular microstrip antenna by loading four equal slots with same dimensions on the radiating patch.

Effect of slots on microstrip patch antenna characteristics - IEEE Xplore

coupled antenna performance, to develop a design and tuning procedure, and to describe. performance effects through electromagnetic principles. Antenna parameters examined in this study include the dimensions and locations. of the substrates, feed line, ground plane coupling slot, and patch. Microstrip Patch Antennas - University of Texas at El Paso The transmission-line model represents the microstrip antenna by two slots, separated by a low-impedance transmission line of length L. Looking at a cross section of the antenna (x-y plane), this is effectively a non-homogeneous transmission line. Fringing effects make the microstrip line look wider than it is. Effective dielectric
