self‐diplexing antenna (SDA)substrate integrated waveguide (SIW)The authors present a novel self‐diplexing antenna (SDA) designed using substrate‐integrated waveguide (SIW) technology. The antenna features a planar‐backed cavity with a radiating slot and two input ports tuned to produce two ...
A design of a half-mode substrate integrated waveguide (HMSIW) cavity-backed self-diplexing antenna is proposed with a two-layer structure. The top layer comprises two HMSIW based cavities, and radiating patches are etched on the top-cladding of each cavity. The radiating patches are excited by...
the beamscanning capability of a four-element, self-diplexing antenna was studied. It was found that infinite isolation between the transmit and receive ports can be obtained when the beam is scanned in the direction of the orientation axis....
A self-diplexing antenna based on S-QMSIW was designed, fabricated and tested to claim the proposed concept. At 3.45 and 5.45 GHz, the proposed antenna peak gains are 4.7 and 5.6 dBi, respectively. It offered port isolation better than 38 dB. The antenna front-to-back ratio was greater ...
CIRCULAR POLARIZED WAVE SELF-DIPLEXING ANTENNAPURPOSE: To increase the isolation between the transmission and reception terminals and also to reduce the size of a receiver by providing a phase corrector means between two feeding points of a reception antenna and an adding means.TAKAHASHI TOSHIMASA...
Self-diplexing antennasubstrate integrated waveguide (SIW)This paper presents a wideband self-diplexing antenna in substrate integrated waveguide (SIW) technology. The problem of narrow radiating bands of traditional self-diplexing antennas is first solved by introducing stepped-impedance resonant slots ...
A compact high-isolation self-diplexing antenna is designed on a single-layered substrate integrated waveguide (SIW) cavity for dual-frequency communication in C-band. The antenna design procedure is straightforward. The antenna is backed by an SIW cavity for possible low back-lobe radiation and ...
PURPOSE: To provide a self-diplexing array antenna which can perform the simultaneous transmission/reception and also ensures the circularly polarized waves for both transmission and reception using many elements that secured the isolation between the transmission and the reception where the transmission ...
SDAtuningThis article investigates the possibilities of frequency tuning of a Self-diplexing antenna (SDA) using different liquid dielectrics. Tuning analysis is carried out using the fluidic pockets introduced into the substrate by drilling blind vias starting at the bottom layer. To examine the ...
PURPOSE: To increase the isolation between the transmission and reception terminals and also to reduce the size of a receiver by providing a phase corrector means between two feeding points of a reception antenna and an adding means. ;CONSTITUTION: When a left turn circular polarized wave is ...
