Abstract EN
A substrate integrated waveguide (SIW) slot antenna with wideband bandpass filtering performance is proposed in this journal.
It consists of a SIW cavity, a transverse slot, three metal posts, and a SMA connector.
Three metal posts split the SIW cavity into two TE110-mode resonators.
A long nonresonant transverse slot is utilized to realize a half TE110-mode resonator and generate radiation simultaneously so as to reduce the size and release the use of extra radiator.
Three in-band resonance poles and a radiation null at both out-of-bands are obtained.
A prototype is fabricated and measured.
Measured results demonstrate the proposed antenna is with a center frequency of 4.26 GHz, a fractional bandwidth of 9.1%, a high efficiency of 93%, and flat gain response and good skirt selectivity of 270 dB/GHz and 330 dB/GHz for the lower and upper out-of-band, respectively.
