Optical switching concerns using photoconductive switches, while mechanical switching involves the physical movement of radiating parts [3; 6]. Finally, \"smart materials\" that can alter their characteristics, like graphene, liquid crystals, liquid metals, etc., can also be used for reconfigurable antennas [7]. Many researchers have presented simulation results of reconfigurable antennas of various geometries [8]. In some cases, only the proposed antenna is also implemented. The authors of [9] simulated and implemented a reconfigurable antenna with a flower-shaped patch, operating in the WLAN and WiMAX bands. Their frequency switching relied on a single varactor diode, and the effect of altering the diode's positioning was tested. An antenna using two PIN diodes is presented in [10], covering several frequencies from 3.1 to 9.5 GHz, while changing the radiation pattern for different operation modes. A multiband frequency reconfigurable antenna was designed and implemented in [11]. Three PIN diodes were placed on the ground plane providing the switching mechanism for frequencies between 1.36 and 8.6 GHz. In [12], the authors used six PIN diodes on a pixel antenna, achieving three configuration modes with resonant frequencies at 2.6, 3.9, and 10 GHz.
