This paper presents the design of a multiband square patch antenna with Sierpinski gasket slot in top surface of substrate and Koch loop shape slot in ground. This antenna has been designed to operate within 0.1GHz to 3 GHz frequency range. The antenna has been simulated using IE3D simulator software. The experimental result of the proposed antenna exhibits the five bands. Keywords-Square Patch...

New design of obtaining a dual frequency bands antenna operate on the dual frequency bands of the Global System for Mobile Communications (GSM) (Lower band = 900 MHz, Upper band = 1.9 GHz) with a single-feed square micro-strip antenna are proposed and experimentally studied. The proposed designs are based on the same patch dimensions configured with one rectangular slot in the form of cut insid...

A novel coplanar waveguide (CPW) fed wide tapered slot antenna (WTSA) is presented in this paper. A wideband CPW-towide slotline (WSL) transition is employed to feed the antenna. The corrugated edge structure and broken line tapered profile are also applied in this design to achieve wideband performance, as well as maintain compact size. A prototype of the antenna is fabricated. The measured re...

Since the FCC has announced to allow the unlicensed use of the industrial, scientific, and medical (ISM) frequency band by any potential users, wireless communications community has provided enormous opportunities for driving many wireless systems that can be communicated over short distances. For example, some practical applications are operated at the internationally available unlicensed ISM ...

This paper presents coplanar waveguide (CPW) fed slot antenna. A rectangular slot antenna is excited by a 50 ohm CPW with L-shaped tuning stub. It can achieves wide band from 2.0 GHz to 6 GHz which is the frequency band covered the standard IEEE 802.11a/b/g for use in WLAN (Wireless Local Area Network) and covered the WiMAX (Worldwide Interoperability for Microwave Access, 2-6 GHz). The charact...
