Abstract:
A Dual Band Double Slot Loaded Microstrip Patch Antenna is designed. Diagonal Co-
axial feeding tecnique is used to feed the antenna. The dielectric used is FR4 with its
dielectric constant 4.4 and permittivity 2.2. Rectangular Patch is used as a radiator on
which two narrow slots are made. These slots make the antenna frequency and polarisation
recon gurable. The gain is 7.8 dB at 4.9GHz and 7.1 dB at 4GHz. The antenna is analyzed
and stimulated using HFSS software. The proposed antenna provides circular polarisation
both LHCP and RHCP. This antenna has an overall dimension and the dimension of slots
created over patch is which is very compact compared to the conventional antenna.
