A novel compact, dual layer UWB monopole antenna is presented. This low profile ultrawideband antenna is fed by a 50 Ω shielded strip-line with an array of metal vias making the conducting walls. A printed disc monopole with a circular cut is the radiating element. The dual layer, shielded strip line feed allows for integration in multilayer technologies. The ultra-wideband, monopole characteri...

In this paper, a novel dual notch bands Ultra Wide-Band (UWB) antenna for WLAN and WiMAX applications is presented. The antenna contains a taper rectangular monopole antenna with new feed line which is designed and modified for 2–12 GHz. To achieve notch band at WLAN frequencies, different methods are compared such as L-shape slots for one notch or dual rings in notch designing. On the other ha...

In this article, a printed triangular-shaped monopole antenna is proposed for emerging ultrawideband application. The proposed antenna uses a triangular radiating patch which is directly fed by a 50-X microstrip feed line. To improve the impedance bandwidth, a round-corner ground plane has been used. To further improve the impedance bandwidth for the entire band, a microstrip transition (near t...

In this paper, we have investigated printed monopole antennas, which is basically printed microstrip antenna with etched ground plane for UWB applications. In particular, we have simulated two types of UWB printed monopole antennas: circular and modified circular disk monopole antennas. Simple rectangular microstrip lines are used for feeding the printed monopole antennas. This UWB monopole ant...

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...

Several wideband antennas are presented for either wireless application. This paper presents the performance of a simple monopole antenna loaded with an annular dielectric resonator as a wideband transmitting/receiving antenna. By adjusting the length of the monopole and load arm, a 10-dB bandwidth of 94% is achieved while maintaining monopole-like radiation pattern, which covers UWB applicatio...

The proposed antenna comprises a Y-shaped quarterwavelength monopole antenna surrounded by two iterations of eight conductive arched walls acting as para...

A novel compact coplanar waveguide (CPW)-fed printed antenna with triple bands for WLAN and WiMAX applications is presented. By using a parasitic circular patch, a pair of symmetrical inverted-L strips and a 50-Ω transformer, the antenna can effectively provide a good input impedance matching. The tuning effects of the ground size, the parasitic circular patch and the symmetrical invertedL stri...

A novel design for a simple rectangular ring with open-ended monopole antenna wireless local area network (WLAN) applications is proposed in this article. The proposed antenna consists of an open-ended rectangular ring, an inverted L-strip, and a rectangular slit in the ground plane, and is fed by a 50 Ω microstrip feed-line. Prototypes of the proposed antenna were designed, fabricated, and tes...
