Analysis of a Gap-coupled Stacked Annular Ring Microstrip Antenna

A theoretical analysis of a gap-coupled stacked annular ring microstrip antenna with superstrate is performed in order to obtain wider bandwidth operation. The effects of air gap, superstrate thickness and feeding point location on the antenna performance are analyzed in TM11 mode using equivalent circuit concept. It is noted that the proposed antenna is very sensitive to the feeding point loca...

Computational Analysis of Annular Ring Slot Loaded Microstrip Antenna

This paper presents an investigation conducted on annular ring slot loaded microstrip antenna operating in triple band and it is found to exhibit frequency tunability with the slot angle. Return loss of the proposed antenna has been investigated as a function of slot angle ? with fixed coaxial feed location. It is found that the said parameter of antenna depends heavily on the slot angle ?. Res...
