A compact dual‐band hook‐shaped antenna for wireless applications

<jats:title>Abstract</jats:title><jats:p>In this article, a dual‐band coplanar waveguide‐fed antenna is proposed for wireless local network. The dimensions of the antenna are 18 × 17 × 1.6mm<jats:sup>3</jats:sup> fabricated on FR‐4 substrate. It comprises narrow hook shaped slits on left‐hand side and two separated ground planes. The measured results show that the proposed antenna has impedance bandwidth from 2.0 to 2.56 GHz and 4.59 to 6.0 GHz for 10 dB return loss. It can cover several wireless communication bands like UMTS 2100 MHz, Bluetooth 2400 MHz, WLAN 2400/5200/5800 MHz, and LTE 2300–2400 MHz bands. To validate the results of simulation, an inexpensive FR‐4 substrate is used for the fabrication of the prototypes of the proposed antenna and tested. Experimental and simulated results obtained indicate that the proposed antenna has good radiation efficiencies and near omnidirectional radiation patterns.</jats:p>
