This paper proposes a compact sized dual band microstrip patch antenna with microstrip feed line. The
patch of antenna is a rectangular shaped patch which has a circular slot in the patch for multiband operations. This
antenna covers frequency bands, centered at 2.4GHz, 3.3GHz, which is useful for the C-band and X-band
operations. In this paper, a microstrip patch antenna with compact size of 21x17x1.6 mm in rectangular shape. This
antenna is designed on FR4 substrate (Dielectric constant=4.4) of thickness h=1.6mm with ground of size 25x10
mm. The proposed structure were simulated on CADFEKO simulation software. This proposed antenna is suitable
for multiband wireless communication systems and mobile equipments.
