To implement the compactness in size, these structures are etched on the ground plane, then the input impedance has been improved. The CSRR is employed to improve impedance matching between the source and radiation patch, and the cross-shape slot on the radiation patch is utilized to increase the bandwidth. The design is validated by comparison of realistic field simulation with measurement results of an antenna prototype. The presented antenna is much smaller in size than conventional antennas with CSRR, showing good performances at the resonant frequency. The experimental results accord well with simulated results.展开更多

This work uses a complementary split ring resonator between the patch and the ground plane for the purpose of size miniaturization. The proposed antenna system is capable of operating in the frequency range of about 2 to 5 GHz. This wide-band design makes it viable for wide spectrum with 80 percentage effective frequency being covered in the designed band.

文摘A compact patch antenna is designed, which is with structures of cross-shape slot, Complementary Split Ring Resonator(CSRR), and loaded transmission line. To implement the compactness in size, these structures are etched on the ground plane, then the input impedance has been improved. The CSRR is employed to improve impedance matching between the source and radiation patch, and the cross-shape slot on the radiation patch is utilized to increase the bandwidth. The design is validated by comparison of realistic field simulation with measurement results of an antenna prototype. The presented antenna is much smaller in size than conventional antennas with CSRR, showing good performances at the resonant frequency. The experimental results accord well with simulated results.
