Multiband Slot Antenna with DGP for Future Wireless Applications

This manuscript describes a multiband slot antenna with a defective ground structure at ground plane for future wireless applications. The Global Positioning System (GPS), Wireless Area Network (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), V2V communication, and X-band and C band for satellite communications are all supported by a six-band microstrip multiband slot antenna. Six distinct frequency bands are created by utilizing a T curved microstrip patch, inverted one T curved stub, two E curved stubs, and a rectangular slot at the ground plane with a compact size of 48x18mm2 (where Ag is the guide wavelength). The form factor of filtering antenna is miniature than the other antennas discussed in the literature. The six-band slot antenna is proposed using IE3D software. We got good simulation results to show that the antenna is designed for multiple frequency bands from 1.347-1.46GHz for the GPS system, 3.256-3.527GHz for Wi-MAX, 5.074-5.431GHz for IEEE 802.11a WLAN, 5.825-5.974GHz for IEEE 802.11p V2X communication, 7.146-7.429GHz for C band and 8.275-8.684GHz for X band in satellite communication.
