This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

A compact triple band rectangular microstrip antenna (RMSA) for WLAN / WiMAX applications is proposed. The antenna operates at three resonance frequencies 2.4/3.2/3.5GHz Covering the WLAN/ WiMAX operating bands, IEEE WLAN protocol 802.11 b/g employs 2.4 GHz and WiMAX 3.5 GHz. The antenna was studied by means of simulations as well as practical measurements. The Triple band characteristics of an...

A novel dual-band microstrip antenna for an internal notebook antenna for WLAN operation is presented. The antenna has a simple structure consisting of a spiral strip. The proposed antenna has a low profile and can easily be fed by using a 50 Ω microstrip line. It is believed that the size of the antenna is about the smallest among the existing internal laptop antennas for 2.4/5.8GHz WLAN opera...

An investigation into the effect of ground slot in a microstrip antenna is presented. Initially, a planar inverted-F antenna dedicated for 2.45 GHz WLAN lower band is designed. Its rectangular ground plane is then introduced with slots to excite new magnetic resonance for 5.2/5.8 GHz WLAN upper band. The slots are optimized by tuning their three different configuration parameters which are the ...

This paper describes a novel dual-band patch antenna on organic magnetic substrate for wireless local area networks (WLAN) wireless communication (at 2.4 and 5 GHz). The dual-band operation is obtained by embedding a pair of L-shaped slots. The magnetic material is adopted because the substrate can reduce the size of antenna 40%, comparing with rectangular microstrip antennas on normal dielectr...

This antenna effectively covers both 2.4GHz and 5.2GHz bands. The return losses of the measured results are in agreement with simulated results, the measured S parameters and radiation pattern showed that the proposed design is ...

This paper presents a dual-band dual-polarized antenna array design for WLAN applications. Four double-dipole elements are orthogonally interleaved to facilitate operation in both the standard WLAN frequency bands (IEEE 802.11b and IEEE 802.11a) simultaneously. The two linear polarizations have separate ports. The presented design is characterized by dual-band operation, reasonably good front-t...

A novel CPW-fed antenna capable of triple-band operation for WLAN/WiMAX applications is presented and investigated in this paper. The proposed antenna simply consists of three elements viz. folded open stub, L-shaped open stub, and Y-shaped resonator. By using the three elements, triple-band antenna operating at 2.5/3.5/5.5 GHz can be achieved. The antenna impedance bandwidths for |S11| ≤ −10 d...
