In this paper, a triangle-shaped Quarter Mode Substrate Integrated Waveguide (QMSIW) cavity back slot antenna is developed using TE 110 , TE 220 , and TE 310,130 modes for tri-band operation. The QMSIW is obtained from the quadrant part of a square SIW (Substrate Integrated Waveguide) structure. The electric field distributions of resonant modes are studied for the Full Mode SIW, Half Mode SIW, and Quarter Mode SIW cavities through HFSS simulation tool. The generation of the hybrid mode TE 310,130 mode is clearly explained with the simulation tool. A rectangular slot is engraved on top layer of the structure along the perfect electric wall, to radiate the EM (Electro Magnetic) wave towards positive Z-direction. Further, a metallized via has been inserted to bring reflection coefficient below −10 dB at the three resonant modes. The developed antenna achieves resonance at 5.2 GHz, 9.88 GHz, and 10.6 GHz frequencies with peak gains of 9 dB, 6.2 dB, and 7.9 dB, respectively. The antenna is designed on a single layer thin substrate which reduces the fabrication complexity.

“…Moreover, fractal based antenna was proposed to improve the efficiency of a partial ground plane antenna when two diodes were connected to the fractal structure [16]. therefore, the authors in [17] proposed design of Double H-Slot Microstrip patch that operate on three frequencies to enhancement gain and to change radiation pattern in many directional. In this paper, the authors give a systematic study of a reconfigurable printed antenna design based on fractal structure for 5G applications.…”

a reconfigurable antenna design for 5G applications is presented. It is based on monopole antenna and fractal structure. The design structure is consisted of (monopole) feedline, ground plane, L-shape reflector, fractal structure and PIN diodes. The antenna is printed on (25×29×1.6 mm3) FR-4 substrate of εr=4.3 and tanδ =0.001. The antenna shows a resonant frequency at 4.1 GHz with S11=-11.4 dB and Omni-direction pattern of 1.21 dB gain. The L-shaped reflector is used to maintain the radiation pattern in a specific direction. Moreover, the proposed fractal structure is found to operate as a circuit to give another resonant frequency and enhance the antenna performance. Where it is used to give more manipulation in the antenna performance including: frequency resonance and radiation patterns. The PIN-diodes are used to give many cases for more current manipulation. moreover, the authors used RF (50 SMA port) between monopole antenna and right side of ground plane to optimize directing radiation pattern and to eliminate the problems of interference between AC and DC current that produced from using PIN diode. This manipulation leads to change the resonant frequency and radiation pattern to the desired direction.So all parts are printed on a single side of FR4 substrate
