Abstract
En 中文
A novel method is proposed to achieve a single layer miniaturized multiband side-fed microstrip patch antenna for mobile communication applications. Unlike the conventional microstrip antenna with a microstrip line side feed, the integration of a rectangular strip, triangular radiation element, and off-set octagonal radiation patch contributes to the impedance matching, radiation of the multiband signals, and reduction of the length of the regular side-fed antenna. The analysis reveals that a TM01, TM21, and TM22 modes at 1.85, 2.3, and 3.38 GHz, respectively, are excited to realize the multiband radiation. The measurements show that the proposed antenna can work in the 1850/2310/3380 MHz multiple frequency bands simultaneously and can be integrated with planar circuits using a simple structure.
