This paper presents a CPW-fed compact inverted L shaped microstrip antenna for wireless applications. The proposed antenna provides an omni directional radiation pattern and it utilizes the concept of coplanar wave guide (CPW). The main motive is to simplify the structure and to reduce the overall size of the antenna. This is done by loading the inverted L-strip over the conventional monopole p...

This paper describes a compact triple-band monopole antenna based on Open Complementary Split Ring Resonators (OCSRRs) for Wireless Local Area Network (WLAN) and Worldwide interoperability Microwave Access (WiMAX) applications. The monopole antenna with engraved ground plane is used to cover WLAN frequencies (2.67GHz and 5.47GHz). The resonant frequency of WiMAX (3.43GHz) is achieved by introdu...

A novel design of a CPW fed printed monopole antenna for dual polarization applications is proposed in this paper. The monopole is formed of a rectangular patch embedded with a hour-glass shaped slot. In a modified version of the antenna, an additional spiral shaped slot is incorporated in the ground plane. The overall dimensions of the antenna are kept at 40× 40mm. The impedance bandwidth achi...

A compact printed ultra wideband (UWB) monopole antenna with multi-notched characteristics is presented. By inserting multiple E-shaped slot in micro strip feed line and ground plane, additional resonances are excited. The multi notch has been created by embedding a pair of – L shaped arm in the radiating patch and a modified E-slot defected ground structure in the feeding line. The designed an...

A novel approach for the design of a compact multiband monopole antenna for improving radiation characteristics at higher resonant frequencies is presented. The proposed structure consists of a conventional printed monopole loaded with spiral ring resonators and fed by microstrip. When at higher resonant frequency, the electrical length of the conventional monopole antennas is relatively large ...

A new planar monopole antenna which covers 3G, Bluetooth, WiMAX, and the UWB bands and also exhibits dual band-notched characteristic is presented. Presented antenna consist a square radiating patch with a pair of L-shaped slits, and two U-shaped slot and a ground pale with a V-shaped strip. The proposed antenna has been successfully simulated and measured. Experimental results shows that the p...

In this paper, a compact ultra wideband (UWB) monopole antenna with a band-notched characteristic is presented. The bandnotched characteristic is achieved by inserting a U-shaped slot in the half elliptical ring radiating patch. The measured bandwidth of the designed antenna for |S11| 6 −10 dB spans 3.1 GHz to 9.3 GHz with a notched band (|S11| > −10 dB) spanning 5.12GHz to 5.99 GHz. A quasi-om...
