A Novel Substrate Integrated Waveguide Back-cavity Antenna with Bow-tie Shaped Slot
As substrate integrated waveguide cavity-backed antenna with narrow rectangular slot always be narrow banded,a novel cavity-backed antenna with bow-tie shaped slot is proposed.Bow-tie shaped slot is integrated on the SIW cavity to wide the bandwidth.Design and simulation process are also given in this paper,the key parameters affecting the performance of antenna is studied,and test sample is fabricated and tested.Test results show that 3.96%relative bandwidth and 4.9 dBi gain are obtained at the antenna center frequency 5.3 GHz.The simulation results coincide well with simulated results,verify the validity of the designing.
