Abstract

In this paper, a surface‐mountable, reconfigurable monopole antenna was designed for array antenna operations in the DCS‐1800 and PCS‐1900 bands. First, the elementary structure was obtained by folding a metallic strip into a V‐shape, and then soldered to a 50‐Ω microstrip feed line printed on a metallized substrate. For the optimized structure, an impedance bandwidth of 22.7%, corresponding to the frequency range 1560–1960 MHz, was obtained. Measured radiation patterns are similar to that of a monopole antenna, and the maximum measured gain is about 1.8 dBi at 1.6 GHz. Next, this elementary antenna was used for realization of both linear‐ and planar‐array antennas. The linear‐array shows a dual and wideband behavior with good impedance matching and asymmetric radiation patterns, whereas the planar‐array presents a unique resonant band with moderate adaptation and symmetric radiation patterns. The measured gain for the two arrays is about 5 dBi. © 2007 Wiley Periodicals, Inc.
