[IEEE 2019 6th International Conference on Image and Signal Processing and their Applications (ISPA) - Mostaganem, Algeria (2019.11.24-2019.11.25)] 2019 6th International Conference on Image and Signal Processing and their Applications (ISPA) - Gain Enhancement of Microstrip Sawtooth Antenna Array based on Substrate-Integrated Waveguide Technology for Dual-Band Applications (Ku / K)

摘要： This paper introduces and studies a new approach to enhance the gain of Microstrip Antenna Array using the substrate integrated waveguide (SIW) in (Ku/K) band applications. The integration of SIW is first implemented in a single microstrip antenna and then in a 1x2 antenna array. This development is based on two designs, one for the 1x2 antenna array with microstrip feed-line with SIW and the other for the inset feed-line with SIW. All these structures are designed and simulated using the Rogers Duro?d TM5880substrate (εr= 2.2 and h = 0.5mm) by means of the High Frequency Structure Simulator (HFSS). The proposed design improved gain and sufficient bandwidth. Therefore, the maximum bandwidth and gain obtained from the 1x2 SIW sawtooth antenna array is 410 MHz and 9.27dBi respectively. In the end, the validation of the design 1x2 SIW antenna array is done by simulating the same antenna with another software CST. The results obtained from the both simulation software show a good agreement.
