摘要：
In this letter, a reconfigurable antenna for mobile handset applications is proposed. This antenna mainly consists of a longer strip, a shorter strip, and a p-i-n diode. Coupling is generated at the gap between the longer strip and the shorter strip. Depending on the different states of the p-i-n diode, the degree of coupling between them is controlled, and the fundamental resonant frequency of the proposed antenna is adjusted. As a result, the proposed antenna in the low band covers the LTE700/GSM850/900 bands. The high band is formed by combining higher-order mode of the longer strip and quarter-wavelength mode of the shorter strip to cover the GSM1800/1900/UMTS/LTE2300/2500 bands.
