Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>This article proposes a mobile embedded antenna having tunable capacitance, and the validity of the proposed solution has been proven through its design, fabrication, and measurement. The antenna can be applied to long‐term evolution (LTE) and DCS/PCS/wideband code division multiple access bands that are currently being used. The 4G mobile service requires antennas to expand its bandwidth so that it can include the LTE band and other service bands. However, it is difficult to obtain the low‐band frequency due to the limited space for antennas in terminals. The proposed antenna with a PIN‐diode was added to a basic planar inverted‐F antenna structure to satisfy the intended bandwidth through the ON/OFF characteristics of the PIN‐diode. To meet this requirement, a PIN‐diode (MA4P274–1279T) manufactured by MACOM, was used to make the operation frequency of the low‐band tunable. The antenna was fabricated and then measured using the optimized parameters, and the results have been compared with the simulated results. The antenna satisfied the requirements for operation frequency and performance for both low‐band and high‐band frequencies. The measured performance of the antenna fabricated with the optimized parameters was analyzed and compared with the simulation results. © 2015 Wiley Periodicals, Inc.
