Abstract
A frequency-reconfigurable antenna for a mobile phone with small volume is proposed. The proposed antenna consists of a planar inverted F-antenna (PIFA) with volume of 4×36×5mm3 and a monopole antenna embedded in the same space. The two antennas are excited by two separate feeds with a common ground plane. A switch is used in the PIFA for frequency-reconfigurable operation. The PIFA can cover either LTE (698-806MHz) or GSM900 (880-960MHz) depending on the state of the switch. The monopole antenna can cover either PCS1900 (1.85-1.99GHz) and m-WiMAX (3.4-3.8GHz) or WLAN 802.11a (5.15-5.35GHz) depending on the state of the switch. The antenna gain is in the range of -1.99-0.61dBi over 700MHz-2GHz bands and 2.39-4.62dBi over the bands higher than 3GHz. The proposed antenna is shown to have good radiation characteristics.
