Dual-band L-shaped SIW Slot antenna

Abstract

Dual-band L-shaped substrate integrated waveguide (SIW) Slot antenna is proposed in this paper. The proposed L-shaped structure is constructed using two different slots oriented along longitudinal and transversal direction to feed. The longitudinal slot produces single band measured response with frequency range of 13.16 GHz to 13.38 GHz with 13.28 GHz as the center frequency. Along with, the transversal slot produces single band measured response with frequency range of 10.18 GHz to 10.34 GHz with 10.25 GHz as the central frequency. These two different slots are combined into a single L-shaped slot, which produces dual band measured response with frequency range of 10.84 GHz to 11.01 GHz and 12.60 GHz to 12.78 GHz. The center frequencies are 10.93 GHz and 12.69 GHz. The gain of the designed antenna is 6.58 dB and 6.82 dB at 10.93 GHz and 12.69 GHz, respectively. The analysis is carried out using the HFSS software, and the simulated results are verified using the measurements. Index Terms -Dual-band/multi-band, microstrip, SIW, slot antenna, waveguide.

Bowtie slotted dual‐band SIW antenna

“…The measured −10 dB operating bands are obtained in the range from 10.13 GHz to 10.64 GHz and from 11.41 GHz to 12.25 GHz with fractional bandwidth of 4.94% and 7.14% respectively. The proposed dual‐band SIW antenna has large bandwidth compared to the other SIW based dual‐band antenna reported in the literature , . The peak realized gains at three resonant frequencies are 5.23 dBi, 6.53 dBi and 7.41 dBi respectively.…”

“…In Ref. , a combination of longitudinal and transverse slots is used to excite two different modes and hence two narrowband resonances are generated. Triangular ring‐slot is used by Zhang et al in Ref.…”

Dual Band Half Mode Siw Semi Circular Cavity Back Slot Antenna

“…Three antennas have been proposed in [9] using FMSIW circular cavity to operate at X-band in which grounded coplanar waveguide feeding is employed. A dual-band antenna [10] has been proposed to operate at X-band and Ku-band in which an L-shaped slot is placed on the top of the cavity. One of the two arms of an L-shaped slot radiates at X-band, and the other radiates at Ku-band.…”
