Compact Two-Layer Slot Array Antenna for K-Band Applications Based on Substrate Integrated Waveguide
نویسندگان
چکیده
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 array leading to considerable reduction in size compared to onelayer SIW slot array antennas that are fed from one end. Fullwave electromagnetic simulations show excellent gain, efficiency, and return loss.

متن کاملMulti Attribute Analysis of a Novel Compact UWB Antenna with Via-fed Elements for Dual Band Notch Function (RESEARCH NOTE)
A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...
