Microstrip Patch Antenna Reconfiguration Ability

The Dual-band microstrip patch antenna exhibits bandwidth and frequency reconfiguration capabilities, as evidenced by the agreement between simulated and measured radiations. The antenna's ability for frequency reconfigurability stems from its patch design flexibility, featuring two cuts at its edges. Table 3 tabulates the measured and simulated antenna gain, along with other enhancements. Notably, the antenna demonstrates radiation pattern reconfigurability at lower frequencies (2.4 GHz, 2.45 GHz, 2.5 GHz) and higher frequencies (5 GHz, 5.2 GHz, 5.4 GHz, and 5.6 GHz). This reconfigurability is consistent across various lower-order and higher-order frequencies, highlighting the robust agreement between the measured and simulated radiation patterns. This work applies to present-day IoT devices.
