  • The narrow bandwidth property of a microstrip antennas is one of the main reasons that restrict its wide usage, the way to broaden the bandwidth of microstrip antennas has been concerned by investigators. A simple and practical method for the design of broadband microstrip antennas is proposed in this paper. To confirm the applicability of the method for the designs of the proposed antennas at L-band, experiments have been carried out. The measured results show the proposed antennas have a bandwidth of 25.7%, its gain in operating band is larger than 8dB. Also, the method proposed in this paper is applicable to the design of other mutilayered microstrip patch antennas.
