A novel design of Dual band triangular serrated micro strip patch antenna was designed with different models of serrations and their simulation results are presented in this paper. Equal spaced serrated triangular shapes are etched on four sides of the patch and its performance characteristics are simulated. The number of elements on each side of the antenna is taken as 5,6,7,8 and all the mode...

This paper proposes a micro-strip patch antenna operate on the dual frequency bands. The proposed antenna design consists of U slotted patch with direct coaxial probe feed technique. The U slotted patch offers a low profile, high gain, broad band and compact antenna. The proposed designs are based on patch loaded with U slots in the form of cut from the sides and center of the rectangular and c...

–The paper presents the good matching between simulated and measured results of dual band and broad band rectangular patch mircostrip antenna with T shaped slot (RPMATSS) for the WiMax Application. This antenna is designed on glass epoxy FR-4 substrate. The performance of this antenna is also compared with that of a simple rectangular patch antenna. The simulated results for this antenna are op...

Microstrip patch antennas are light weight and low profile antennas so use of these kind of antennas are more easy in portable and small communication devices where size is concerned . In this paper the analysis of T –slot rectangular microstrip patch antenna is presented. The antenna is designed for wide applications in C-band space communication and wireless LAN communication systems. The ban...

Ultra Wideband (UWB) is a new emerging and promising technology as it can accommodate higher data over a large bandwidth. we proposed a Printed Square-shape UWB Antenna With Dual Band-Notched Characteristics. A simple square patch antenna has been fed through a 50 Ω microstrip feedline .A rectangular notch has been etched on the ground plane to reject the interference of WIMAX Band (3GHZ-4.7GHZ...

In this paper, a novel dual-band rectangular slot antenna for wireless local area network (WLAN) applications in IEEE 802.11b/g/a systems is presented. The proposed antenna, fed by a 50 Ω microstrip line, has size of 32mm × 28mm × 1.6mm. By introducing a pair of U-shaped strips, the proposed antenna can generate two separate impedance bandwidths. The prototype of the proposed antenna has been s...

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...

In Chinese Compass Navigation Satellite System (CNSS for short), dual-band antennas are more attractive, because they can provide both navigation and communication services. In this paper, we present a dual-band dual-circular-polarized planar spiral-slot CNSS antenna. This antenna works at L band (1616± 5MHz, left-handed circular polarization, LHCP) and S band (2492± 5MHz, right-handed circular...
