Microstrip-line-fed wide rectangular slot antenna for multiband operation

摘要

A design of planar rectangular slot antenna with microstrip-line-fed is presented. The proposed antenna has a simple structure consisting of a modified rectangular slot ground plane, microstrip-line-fed act as a tuning stub of the antenna, placed at the opposite side of the feed. The proposed antenna is developed, and its measured characteristics are good agreement with the simulated results. From experimental results, the antenna can generate two bands centered at about 1.8 and 5.8 GHz to cover the GSM system and Wi-Fi band. Good return loss and radiation pattern characteristics are obtained over the two operation bands.
