Abstract :
A compact inverted-F antenna (IFA) with switchable feeds is proposed in this letter. The antenna occupies a relatively small volume of 50 times 7 times 7 mm3. Two pin diodes are used to switch the antenna between two different working states. The antenna can provide the required bands of GSM850 (824-894 MHz), GSM900 (890-960 MHz), DCS (1710-1880 MHz), and PCS (1850-1990 MHz) with S11 < -10 dB. Measurements including return loss, radiation patterns, and gain are presented to verify the proposed design of antenna.
