Povzetek: A frequency reconfigurable antenna for wireless applications using a fractal antenna structure is proposed. The fractal antenna is composed of a step resonator type which has a mirror image at the vertical axis in the top with a slit and a parallel mirror image at the vertical axis in the bottom without a slit. The resonating frequency of the fractal antenna is controlled by a PositiveIntrinsic-Negative (PIN) diode. Two PIN diodes are connected between the top and bottom of the fractal antenna. With the varying capacitance effect, the four possible modes of operation of the diode are obtained at the dual resonating frequency of 2.7 and 3.2 GHz. The proposed design holds significant potential for applications in Fifth Generation New Radio (5G NR) n1 band, and Wireless Fidelity (Wi-Fi) access points due to its small size and easy control mechanism. The Specific Absorption Rate (SAR) values were analyzed and are within the safety limits.
