Abstract :
The stripline aperture coupling structure is introduced to lower the back radiation of a broadband low-profile metamaterial mushroom antenna. Compared to the feeding structure of a microstrip line aperture coupling, the stripline aperture coupled mushroom antenna exhibits a front-to-back ratio enhancement of 2-14 dB within an operating frequency range of 4.7-6.0 GHz.
