The proposed antenna utilizes the advantages of the CPW line to simplify the structure of the antenna into a single metallic level, thereby making easier the integration with the microwave integrated circuits. Four operating modes of the proposed antenna are associated with various lengths of four monopoles. The structure of T-shaped monopole antenna and L-shaped monopole antenna are used in the design of the multi-band microstrip antenna. Experimental results show that the bandwidth, determined from 10-dB return loss, is greater than 50 MHz for four operating frequencies. Details of the experimental results are presented and discussed. The size of antenna is 37mm × 34mm.
