  • Abstract An aperture-coupled patch antenna is presented. The aperture is composed of two L-shaped-like slots and is proximately-fed by an L-shaped-like strip.
    The L-shaped-like strip is first coupled to the first slot through its vertical arm , then serially coupled to the second slot through its horizontal arm. 
    The length of the vertical and horizontal arms of the L-shaped strip are found highly correlated to the axial- ratio bandwidth of the antenna. The center frequency in the return-loss plot of the antenna is also influenced by the two lengths. The optimized antenna has a return-loss bandwidth of 19.6 % (2.26-2.75 GHz) and an axial-ratio bandwidth of 16 % (2.3-2.7 GHz).
