Design of Multiband Slot Antenna for WLAN

Wide-band Slot Antenna for WLAN Application

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...

Slot Perturbation of Rectangular Patch Antenna for Multiband Behaviour

A corner cut micro strip patch antenna having H slot with small micro strip line feed is presented here. Different design parameters with their effects are studied using v11 Ansoft HFFS. For the operational frequency of 1.8 GHz(1758-1848Mhz), 3.3Ghz(32853454Mhz) and 4.6Ghz(4600-4748Mhz) VSWR bandwidth nearly 1.38 and return loss bandwidth up to -19.75db has been obtained. H slots and corner cut...

Designing of Reconfigurable Multiband Antenna for WLAN Application

Multiband and Wideband Planar Antenna for WLAN and WiMAX Applications

Abstract—In this paper, the design of a multiband antenna for WLAN and WiMAX applications is proposed. The proposed antenna comprises a circular radiating patch with a pair of rectangular slits and an inverted U-shaped slot. A hexagon-shaped slot is cut on the ground plane. By adjusting the inverted U-shaped slot, a pair of rectangular slits, and a hexagon-shaped slot, three distinct resonance ...

Enhanced Bandwidth Multiband Slot Antenna for Portable Devices

A microstrip patch antenna with slots is designed and simulated for wireless portable devices. The proposed antenna has a simple structure with a common size of 70 X 20 mm in a 0.8mm thick FR4 substrate with a dielectric constant (er) 4.4. With the proposed antenna structure the two wide operating frequency bands of 1.1 and 2.1 GHz can be achieved at 6.18dB gain can be used for GSM and UMTS net...
