Abstract
This paper presents a novel compact microstrip patch antenna for three-band application, consisting of a main straight arm and four spiral branches. This antenna is characterized by the very small size of only 0.191 /spl lambda/g by 0 212 /spl lambda/g at the first resonance frequency of 5.34 GHz, which represents a size reduction of 60% compared to a conventional rectangular microstrip patch antenna. The results indicate that the return loss is better than 10 dB and that the gain is about 6 dB in each band.
