Abstract:

In this paper, a frequency reconfigurable
microstrip patch antenna having a partial ground
plane and U-slot on the patch has been designed. The
antenna is made reconfigurable by switching the
different diodes placed on the U-slot of antenna. The
antenna works for the entire UWB (3.1-10.7 GHz)
when the diodes are at a particular state with
minimum attenuation of around -23 dB at a frequency
of about 9.4 GHz that can be used for RADAR
applications. This antenna can be switched to
different notched UWB based on different states of
diode. The frequency band of 5-5.9 GHz has been
notched thus removing the interference from WLAN
band. The antenna has been designed for MIMO
applications, here two antennas have been used and it
is observed that both are working independently of
each other on the designated frequency band. The
antennas are having high isolation and a very low
value of correlation coefficient.
