An SIW Cavity-Backed Self-Diplexing Antenna

A self‐diplexing MIMO antenna for WLAN applications

“…Various design techniques of self‐diplexing antennas are presented in literature . Different multilayered structures are reported, where either patches, printed at different layers, are excited by two separate ports or different layers with filtering structures are used to obtain better isolation .…”

“…As discussed earlier, a self‐diplexing antenna based on mode analysis technique is presented. Recently, few designs of single layered planar self‐diplexing antennas, based on substrate integrated waveguide (SIW), are reported …”

“…Various design techniques of self-diplexing antennas are presented in literature. [1][2][3][4][5][6][7][8][9] Different multilayered structures are reported, where either patches, printed at different layers, are excited by two separate ports 1,2 or different layers with filtering structures are used to obtain better isolation. 3,4 However, the multilayered designs are not so easy to integrate with modern compact handheld wireless devices.…”

“…Recently, few designs of single layered planar self-diplexing antennas, based on substrate integrated waveguide (SIW), are reported. [7][8][9] In this letter, a planar, compact 2 × 2 self-diplexing MIMO antenna is presented. To the best of the authors' knowledge, the combination of the concepts of self-diplexing and MIMO is not reported previously.…”

An integrated low frequency ratio wideband filtering duplex slot antenna

“…Traditionally, a duplexer is utilized for enhancing the isolation between two channels to reduce the interference. In order to further enhance compactness and efficiency of the RF front-end system, the duplex antenna fed by two separate ports with intrinsic high isolation is introduced [2,3,4]. The duplex antenna, integrated the duplexer and antenna modules, will have a more extensive application.…”
