Multiband Slot Antenna with E-Shaped Stripe using Microstrip Feeding

In this study, a multiband slot antenna embedded with E-shaped strip and L-bended microstrip feeding is proposed. In the rectangular slot etched from the bottom ground plane, an inverted E-shaped metal stripe composed of multiple segments is carefully placed and affects the radiation frequency bands. By adjusting the several metal segments, the multiband frequencies can be well controlled and the resultant antenna possessing satisfactory performance covers WLAN 5-GHz band by its 2nd and 3rd operation bands. The measurement results agree well with the simulation ones thus validating the proposed approach.
