“…The quality and efficiency of drone-based surveillance payloads largely depend on the efficient miniature antenna design. Antenna miniaturization techniques broadly include use of fractal geometry concept as a space-filling factor, use of high permittivity substrate, different shape of slots cut in the radiating patch, use of Defected Ground Structure, use of meta materials or a combination of the above techniques [5][6][7][8][9][10][11][12][13][14][15] .…”

Drone based surveillance and communication systems are playing a vital role in modern days for both military and civilian applications. Antennas with low profile, smaller size, and light weight are essential for the realization of these systems. A novel fractal-inspired hybrid microstrip patch antenna realized with Sierpinski gasket fractal slots cut in the radiating patch along with corresponding ground structure simultaneously defected with Sierpinski carpet fractal slots is reported for the first time. The antenna resonates at 2.4 GHz with a measured return loss of 17 dB, gain of 7 dB and measured 3 dB beamwidth is of the order of 70 deg. The current approach leads to the size reduction of the antenna to the extent of 55% in comparison to standard radiating patch antenna resonating at the same frequency. The fractal-inspired hybrid microstrip patch antenna is a promising candidate for drone-based surveillance and communication applications owing to its miniaturization and good directional radiation properties.

“…While in [21,22], the antennas type is basically based on circular slot fractal shapes. Another fractal antenna also is presented in [23] which is designed with a finite ground co-planner waveguide (FG-CPW) circuit. The return losses are found better than 16 dB at 0.92 GHz and 2.45 GHz with fractional bandwidth of 3% at 10 dB return loss.…”

This paper provides a compact substrate-integrated waveguide-based dualfrequency H-fractal slot antenna for the C-band (SIW). From the view of fractal slot antenna, two H-fractal slot shaped elements with 3rd iteration are used to cut currents in two TE modes, which leads to dual-frequency performance and reduces the size. The antenna operating at dual frequency of 4 GHz and 5.7 GHz with gain greater than 5 dB is designed and fabricated. Measured and simulated response of the antenna are introduced as well. The responses showed that the proposed antenna achieved stable dual-frequency performance with total size of 23 × 11 mm², which may be applied for C-band communication systems. The proposed antenna was simulated, analysed, and optimized using computer simulation technology (CST) software.
