dc.description.abstract | The interest in producing frequency selective surface that can sustain the highly selective of frequency demands is getting popular nowadays. Applications such as simultaneous worldwide communication with different satellites, control the transmission in WLAN application, military aircraft system and many more are demanding more highly selective frequency devices as the human being use it every single day. The transmission and reflection characteristics of 3D Frequency Selective Surface (FSS) with two type of design which are Dual Cylindrical (main design) and Dual Square were been discussed in this project. A simulation based investigation shows that the height for both design has significant effect on the stop band frequency selective characteristics of the FSS. This can result in a close band response spaced between band pass and band stop response. A comparison is drawn to the parametric study for both 3D FSS design. For 3D Dual Cylindrical design, a novel of 3D Frequency Selective Surface (FSS) architecture based on a circular ring unit element is presented, meanwhile for 3D Dual Square, the square shape element was been used. The circular ring was made 3D by creating a cylindrical element of a certain height, adding an extra degree of freedom into the structure. By adding the certain height for square element also made the design become 3D structure. The height of the cylinder and square is shown through electromagnetic simulation to have a significant effect on the frequency characteristics of the FSS. For both design, by increasing the height of the dual cylinder and dual square can change the FSS from a band-stop to a band-pass filter response. The center frequency of both band-pass and band-stop responses can also be tuned with adjustment to the length of substrate. Several parametric study analyses were conducted on these new cylindrical and square elements, and a simulation of 3D FSS structure has been constructed and experimentally validated. | en_US |
