Abstract

The development of adaptable and efficient antenna designs has been required due to the growing demand for high-performance wireless communication systems driven by the increasing availability of online video streaming and multimedia devices. The design and implementation of a compact, reconfigurable C-shaped patch antenna that is specifically designed for 5G applications in the sub-6 GHz spectrum is presented in this paper. The antenna, which measures 20 × 30 mm², can operate at five resonance frequencies within the 4 to 6 GHz range. Laser treatment is applied to optimize bandwidth and gain. Following the treatment, the antenna attained a bandwidth of 1100 MHz and an improved gain of 5.2 dBi at 5 GHz, as opposed to its initial gain of 4.3 dBi. The system functioned effectively since the reflection coefficient was less than -10 dB over the desired frequency ranges. The design's stable performance, compact integration, and varactor diode frequency adjustment make it desirable for wireless applications. Results exhibited a considerable match between simulated and measured data, demonstrating the promise of this reconfigurable antenna for next-generation wireless communication systems.
