Low-Profile Asymmetrical-CSRR-Loaded Stacked Microstrip Patch Antenna
Keywords:
Low-profile antenna, microstrip patch antenna, widebandAbstract
By introducing an asymmetrical-CSRRloaded parasitic patch beneath the radiating patch of a traditional low-profile microstrip antenna, a novel stacked antenna with both 22.46% fractional bandwidth, and stable and uniform radiation patterns in the entire operating frequency range is achieved, even the total height is only approximate 0.04?L (where ?L indicates the free-space wavelength corresponding to the lower bound of the operating frequency band). The antenna is designed, fabricated and tested. The experimental results agree with the simulations.
