Abstract
This paper presents the design of a compact dual-band slot antenna for use in the
recently available wireless communication applications. The slot structure of the proposed antenna
is based on an annular slot-ring with Koch snowflake fractal geometry of the third iteration. The
antenna slot structure has been etched on the ground plane of a substrate with relative permittivity
of 4.5 and 1.524 mm thickness. On the other side of the substrate, a 50-Ohm microstrip line has
been etched as the antenna feed structure. The proposed antenna has a compact size of (40 × 40 ×
1.524) mm3. Simulation results show that the proposed antenna could excite two resonant bands.
The lower resonant band extends from (2.38 – 3.03) GHz while the upper resonant band extends
from (4.45 – 5.06) GHz. This makes the antenna suitable for a wide range of currently available
communication services.
