Abstract:
In this paper a star fish shaped microstrip patch
antenna is proposed and its design procedure and characteristics
are analyzed. The shape of the antenna patch is similar to a star
fish, therefore the antenna is called Star fish antenna.The
proposed antenna is able to provide dual band operation in V
band (40-52 GHz) and W band (77-95 GHz) which lie in the
range of millimeter wave frequency. The proposed antenna has 8
branches of unequal length in order to achieve wide bandwidth
in millimeter wave range. Each of the branch resonates at
different frequency which ultimately results in a wide bandwidth
of 30 GHz with an efficient gain of 7.9026 dBi and highly reduced
return loss. Designed antenna has a very compact dimensions of
9x9x2.03 mm3, thus it can be easily fabricated with small handset
devices.
