Compact Sized Dual Band Triangular Patch Antenna Using CSRR for Wireless Applications

Wireless communication has emerged as an indispensable element of our daily lives due to technological advancements. The vast majority of electronic devices are outfitted with the capability to facilitate wireless functionality. In light of the expeditious advancement of multifaceted communication gadgets, these devices are now able to function across a multitude of frequency bands. However, in order to resonate in more than one frequency band, it becomes essential to employ multi-band antennas. Although wideband antennas can resonate over broader frequency bands, their impedance bandwidth and gain are insufficient. Consequently, the utilization of compact multi-band antennas can potentially serve as a solution. In this study, a dual-band antenna design is proposed to enhance antenna performance, specifically targeting Wi-MAX and WLAN bands. The research successfully achieved significant gains in antenna performance and radiation patterns. To achieve size reduction for dual band operation, three complementary split ring resonators (CSRR) were etched on the triangular patch. Moreover, it was observed that the dimension of CSRR and patch can be modified to offer flexibility in the selection of dual frequency operation. The antenna design was implemented by using CST V.12 simulator.
