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 4×36×5 mm3 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 (698–806 MHz) or GSM900 (880–960 MHz) depending on the state of the switch. The monopole antenna can cover either PCS1900 (1.85–1.99 GHz) and m-WiMAX (3.4–3.8 GHz) or WLAN 802.11a (5.15–5.35 GHz) depending on the state of the switch. The antenna gain is in the range of -1.99–0.61 dBi over 700 MHz–2 GHz bands and 2.39–4.62 dBi over the bands higher than 3 GHz. The proposed antenna is shown to have good radiation characteristics.
