Experimental design demonstrates enhanced multiband bandwidth in a compact planar antenna, suggesting viable integration into miniaturized wireless communication devices.
The proposed planar antenna design integrates a unique W-shaped slot within an asymmetrical C-shaped radiating patch and includes irregular rectangular apertures on the ground plane. This innovative structure is developed to support multiple wireless communication standards such as WLAN, Bluetooth, WiMAX, Zigbee, and HYPERLAN applications. The incorporation of C-shaped slots on the patch and modifications in the ground plane play a crucial role in improving impedance matching and enhancing overall bandwidth performance. The antenna exhibits resonant frequencies at 2.57 GHz, 3.52 GHz, and 5.62 GHz, effectively covering several frequency bands used in Industrial, Scientific, and Medical (ISM) applications, as well as wireless local area networks. The enhanced bandwidth performance allows efficient operation over the HYPERLAN 2 frequency band, ensuring reliable data transmission for high-speed wireless communication. With a compact physical dimension of 40 × 26 mm², the antenna design is well-suited for integration into modern compact wireless devices that demand multiband functionality. Its optimized geometry achieves stable radiation characteristics and satisfactory gain across all operational bands, making it an efficient and cost-effective solution for advanced wireless communication systems requiring wide frequency coverage and miniaturized hardware implementation.
