Antenna Array Miniaturization based on Slow Wave HMSIW-SSPP Structure

With the rapid development of information technology, the design of antennas has been put forward on the miniaturization, and systemization. For the purpose of achieving array antenna miniaturized, an antenna array fed in the form of series based on hybrid half mode substrate integrated waveguide transmission line (HMSIW TL) and spoof surface plasmon polariton (SSPP) structure is proposed. The maximum gain of the proposed structure is 11.7 dBi in the band of 14.52 to 14.83 GHz. The miniaturization of the longitudinal size of the array structure is realized.
