Broadband Proximity Fed Gap-coupled C-shaped Microstrip Antennas
نویسندگان
چکیده
The C-shaped microstrip antenna is a compact variation of rectangular microstrip antenna and it has smaller bandwidth as compared to the rectangular patch. In this paper, bandwidth of C-shaped microstrip antenna is first increased by using proximity feeding technique. Further gap-coupled configuration of two C-shaped microstrip antennas on thicker substrate is proposed. It gives bandwidth of more than 300 MHz with broadside radiation pattern and gain of more than 5 dBi over most of the bandwidth. Further gap-coupled rectangular slot cut C-shaped microstrip antenna is proposed. This configuration yields bandwidth of more than 400 MHz.

متن کاملProximity fed Broadband Microstrip Antennas
The broadband microstrip antenna is realized by fabricating the patch on lower dielectric constant thicker substrate in conjunction with proximity feeding technique. Using thicker substrates, a formulation for an edge extension length and design guidelines for strip dimensions in proximity fed broadband antennas, are not available. In this paper, first by designing suspended rectangular and cir...
