A Single-Layer Rectangular Patch Etched With Inverted L-Shaped Slots for Broadband Reflectarrays

This paper presents a broadband reflectarray antenna using single-layer rectangular patches loaded with a pair of inverted L-shaped slots. The rectangular patches have the same dimensions for all elements of the reflectarray and the phase shift is realized by tuning the length of the slots embedded within the patches. Consequently, the abrupt geometry variations for surrounding cells in conventional reflectarrays can be circumvented. The measured results indicate the proposed reflectarray can achieve a broad 1-dB gain bandwidth of 23% with aperture efficiency of 67% at 10 GHz.
