Abstract - This paper present 3 design of array
antenna from type of inset-fed microstrip patch
antenna located at 45º and -45ºand capable to generate
dual-polarization radiation pattern.Combinations of
two patches using quarter-wave impedance matching
technique have been used to design the array antenna
operate at 2.4 GHz with Return Loss (RL) less than -
10dB.Those design were simulated using Microwave
Office 2006 and were fabricated on FR4 substrate with
a dielectric constant εr =4.7,tan σ =0.019 and
thickness =1.6mm.Data analysis also has been done to
compare the results between simulation and
measurement.The result showed that the combination
of more patches in array antenna can improve the RL.
The prototype of 3 design 1x2 array antenna yields a
bandwidth of 5%,HPBW for single element found at
90.07°-89.75° and HPBW for array antenna found at
84.68°-79.05°.
Keyword:Array antenna,,inset-fed,dual-polarization,

1.Introduction
In microstip antenna designs,there have been
interests in the dual-polarization operation,which
increase requirement of polarization diversity in
wireless communication.A dual-polarized microstrip
antenna can be realized by feeding the rectangular
microstrip patch at two orthogonal edges,through
edge feed or probe feed,which excites TM01-and
TM10-mode with orthogonal polarizations [1]–[4].
Both the element itself and its array often achieve
isolation of about -20dB [1]–[3].The most reported
technique for achieving dual polarization is using
different feed mechanisms such as aperture-coupling a
single patch with crossed narrow slots or two offset
narrow slots [5].This technique requires a relatively
complicated feed arrangement [6] or a complex
multiplayer construction [7] to reduce the coupling
between the two feed lines and therefore adds
complexity to the fabrication process.
