This paper represents a circularly polarised microstrip antenna with pentagonal slot. The main aim of this paper is to increase the bandwidth of the antenna. Circular polarisation can be achieved with asymmetries. Pentagonal slot microstrip antenna then associated with some characteristics like triangular slits inserted at the corners, corners of the patch truncated. These operations increased the bandwidth of the antenna as well as provided dual band circular polarised antenna. The operating frequency is 2 GHz. Coax feeding has been used. Roger RT/duroid substrate is used with dielectric constant of 2.2. The proposed antenna is simulated by HFSS 11 Software.
