“…The authors develope a new switch using substrate integrated suspended line (SISL) technology in [9] and report that a multilayer produces better isolation below −40 dB at 1 GHz. In [18], a parallel switched fractal common feeding line switch to provide four identical coupling paths is proposed and produces the isolation of −45.7 dB at 0.99 GHz. A type of bandpass filter (BPF)integrated SPDT switch using frequency-selective star-junction matching circuit technique is proposed in [19].…”

A reconfigurable filter integrated single-pole double-throw (SPDT) switch (FIS) based on capacitor loaded ring resonators is presented in this paper. The design incorporates two PIN diodes between two symmetric square ring resonators. The ring resonators can be switched between allstop and bandpass responses, by adjusting the state of the PIN diodes, allowing the corresponding signal path to be in OFF-state with high isolation or ON-state with bandpass filter response. For demonstration, filtering switch was fabricated and measured for 2.4 GHz applications. The measurement results featured an ON-state low insertion loss of −2.1 dB and port-to-port isolation of −52 dB at the band of interest, and good consistency is achieved between simulated and measured results.

In this paper, a wideband polarization reconfigurable omnidirectional antenna (PROA) based on a single-substrate active metasurface is proposed. By controlling the states of the PIN diodes, the antenna can selectively radiate an omnidirectional linearly polarized wave and an omnidirectional circularly polarized wave. The reflection coefficient, axial ratio (AR), radiation pattern, and gain of the proposed antenna have been analyzed from the perspective of simulation and measurement. The measured results show that the PROA has a wide overlapped bandwidth from 2.87 to 3.67 GHz (relative bandwidth 24.46%). To the authors' best knowledge, this is the first reported wideband PROA based on a single-substrate reconfigurable polarization converter. This study not only offers a novel approach to design PROAs, but also greatly reduces the design complexity of the feed source compared with the traditional design method of PROAs.
