PARAMETRIC ANLAYSIS OF MICRSOSTRIP PATCH ANTENNA ARRAY
INTRODUCTION
A microstrip antenna is characterized by its Length, Width, Input impedance, and Gain
and radiation patterns. Various parameters of the microstrip antenna and its design
considerations were discussed. The designed frequency is 9.4 GHz but right now the
frequency deep was obtained at 8.8 GHz so more optimization needs to be done. Also the
return loss needs to improve. Two optimizations were done concerning patch width.
I. INSET FEED
The edge of the rectangular patch antenna impedance is usually 200ohms to
200ohms hence the feed line is inserted to match the 50ohms requirement. The main
advantage of this feed is that we can make the transmission line smaller, and this type of
feed is difficult for obtaining dual polarization, since it requires dual insert feed location.
The schematic layout of insert feed is given below in Fig.1
