- Abstract
- In this paper, dual feeding structure with microstrip and H-shaped aperture feeding for microstrip antenna is proposed to achieve high isolation. The H-shaped aperture is designed at the center of the ground plane to provide better characteristics than conventional rectangular aperture. The measured isolations for the proposed single and 1 × 4 array antenna along E-plane of aperture feeding are less than 49 dB and -48 dB, respectively.
