A high isolation SIW based Self-diplexing antenna

In this research paper, a SIW-based two-port self diplexing antenna is planned for design with isolation (high). The antenna is sourced by two coaxial feed lines to radiate at operating frequencies 4.75 GHz and 5.65 GHz. A high isolation of 40 dB is achieved by making a triangular shield between the two resonators. The given Triangular shielded high-isolation self-diplexing antenna (TSHISDA) has high inter-port isolation, peak realized gains of 5.2 dBi and 6.2 dBi, and better radiation properties.
