Abstract

A compact dual-band planar inverted-F antenna (PIFA) working in the DVB-T (470-862 MHz) and WiMAX (3300-3800 MHz) frequency bands is presented. The antenna is designed to be integrated in a monitor-equipped device, like a television (TV) set, and meets strict space requirements. The final design fits a volume of 225 × 31× 20 mm³ (L×W ×H). It is composed of a series of branches, properly dimensioned and separated to generate the required resonances. A prototype has been realized with a 0.4-mm-thick aluminum foil, properly cut and folded. Results are shown in terms of reflection coefficient, radiation patterns, and gain. The antenna shows a reflection coefficient less then -6 and -10 dB, and a gain between 2.7 and 4.8 dBi and approximately equal to 3.7 dBi, in the DVB-T and WiMAX bands, respectively.
