| 摘 要： | A dual S shaped micro strip antenna with a realistic feed is proposed for generation of tilted beam radiation pattern pertaining for beam steering applications. To achieve this, four feeding points are located at a distance of 5.6 mm from the antenna centre. These feeding points when excited one by one generate four tilted beams in four different space quadrants, thus yielding a beam steerable antenna. Importantly, since the proposed antenna is symmetrical in the structure, all the four tilted beams have the same radiation pattern characteristics. A further enhancement of the antenna bandwidth is also achieved using 100-μm capacitive coupling between the feed and the antenna strip.

| Abstract: | A dual S shaped micro strip antenna with a realistic feed is proposed for generation of tilted beam radiation pattern pertaining
for beam steering applications. To achieve this, four feeding points are located at a distance of 5.6 mm from the antenna
centre. These feeding points when excited one by one generate four tilted beams in four different space quadrants, thus yielding
a beam steerable antenna. Importantly, since the proposed antenna is symmetrical in the structure, all the four tilted beams
have the same radiation pattern characteristics. A further enhancement of the antenna bandwidth is also achieved using 100-μm
capacitive coupling between the feed and the antenna strip.
