چکیده
This paper presents the design of rectangular, fractal Microstrip patch antenna and their backscattering reduction. These antennas have been designed on εr = 4.3, h = 1.53 mm substrate with rectangular patch dimension 36.08 x 29.6 mm and its 2 iterative fractal patch. The experimental resonant frequency of 2 iterative fractal patch is observed 2.11 GHz in comparison to rectangular patch 2.42 GHz. This reveals the size reduction of patch antenna. The radiation pattern of fractal antenna is as similar to simple rectangular patch but cross polarization level is better in fractal patch. The gain loss of fractal antenna compared with rectangular antenna on resonant frequency is less than 1 dB. The investigation reveals that 2 iterative fractal patch provides low RCS in comparison to other iteration and simple patch. Such type of antenna is useful for wireless communication in defence environment. Index Term —Microstrip antenna, Resonant Frequency, Fractal Antenna, Miniaturization and Backscattering RCS

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
