UWB monopole patch antenna with two H-shaped slots and dual-band notch for WLAN and WiMAX applications; pp. 148–154Full article in PDF format
Ultra Wide Band (UWB) denotes a wireless technology developed to transfer data at high rates over very short distances and at low power densities. In this paper, a highly miniaturized monopole antenna with a dual-notch band is presented for Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) systems. The overall size of the broadband antenna was reduced to 22 mm2 × 20 mm2, which improved the UWB operation in the frequency range (2.4 GHz‒9.6 GHz). Etching two H-shaped slots on the radiating patch of the antenna was implemented to reject the WiMAX frequency range from 3.1 GHz to 3.9 GHz and the WLAN frequency range from 5.1 GHz to 5.9 GHz. Thus, the monopole patch antenna has dual H-shaped slots etched on the radiating patch. The antenna was printed on FR4 dielectric substrate and fed by a coplanar waveguide (CPW). The coaxial feed was used to obtain an impedance matching of 50 Ω. The antenna exhibits omnidirectional and bi-directional radiation performance in the H- and E-planes, respectively. In addition, it was tested and verified in practice.
