Compact Two-Layer Slot Array Antenna for K-Band Applications Based on Substrate Integrated Waveguide Abstract: A compact two-layer slot array antenna at 24GHz based on substrate integrated waveguide (SIW) technology is presented. The feed waveguide is placed underneath the slot array and is coupled through slanted slots to branches of the Design of a Two-Element Antenna Array Using Substrate ... The design of a two-element antenna array using the substrate integrated waveguide (SIW) technique and operating at 10 GHz is presented. The proposed antenna array consists of two SIW phase shifter sections with two SIW slot antennas. Dual-Band Broadband Antennas for SAR Applications For dual-band high-resolution synthetic aperture radar applications, an efficient array design is investigated. The operating frequencies are at X and C-band, centered about 10.0 and 5.5 GHz, respectively. The X-band antenna is a ridged waveguide slotted resonant array, which is subarrayed to improve, the bandwidth. Investigation and Design of a Slotted Waveguide Antenna with ...
