Compact broadband monopole antenna for C band applications

Abstract

This paper reports a new design of broadband monopole patch antenna. The proposed antenna possess corner truncated rectangular patch with slits and defected ground structure, these modifications considerably improves the measured impedance bandwidth to 41.29% over a wideband (5.1–7.59 GHz) while the simulated impedance bandwidth is 46.77%. The design is appropriate for wireless communication including WLAN IEEE 802.11 g/a (5.15– 5.35 GHz and 5.725–5.825 GHz) and C Band (4–8 GHz) applications. An antenna prototype is fabricated using FR-4 with an electrical permittivity of 4.4. Experimental and numerical simulations of antenna’s radiation characteristics are also reported and exhibits good concurrence.
