There has been a flourishing prospect of UWB technology in recent years in both communication and other purposes like microwave imaging and radar applications. Recent studies of UWB antenna structures are specially concentrated on microstrip [1], slot and planar monopole antennas [2]. In this work, a small monopole antenna with diamond shape of the patch (30 x 26 mm2) printed microstrip fed mon...

The scaling factor in a ultra-wideband antenna is investigated. Here is showed that the lower frequency limit of the bandwidth is reduced as the scaling factor is bigger than unity. Using the obtained results a UWB planar monopole antenna was designed. The measured antenna bandwidth goes from 650 MHz to 20 GHz for a VSWR ≤ 2. The radiation pattern remains almost omnidirectional. The radiator us...

An improved novel printed wideband flat-plate monopole antenna is presented. The proposed antenna consists of a pentagonal monopole embedded in a corner notch in the antenna ground plane part. Simulated and measured results of the input return loss for the proposed antenna are in good agreement. The antenna has been shown to operate satisfactorily in the 0.47–6 GHz frequency range, and is there...

A novel monopole internal antenna for mobile handsets is presented. The antenna, called the MB antenna, is a modified monopole whose radiating element is implemented in parallel proximity of a ground plane hence allowing for use as an internal antenna in handset applications. Simulation studies indicate that the proposed MB antenna has superior performance over PIFA antennas commonly used in mo...

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...

A novel monopole-type antenna, which covers the bandwidth 3.1 10.6 GHz is presented. The shorted and folded planar monopole antenna is constructed by folding a thin copper sheet in such a way that one edge of the radiating element is connected to the ground plane. Simulated and measured results show suitable characteristics for communications systems using ultrawide-band (UWB) technology. Moreo...

This paper proposes a monopole antenna with photonic crystal structure as substrate for ultrawide band application with dual band notched characteristics.Improvements in all the main parameters of the antenna were obtained when using a PC.The measured results reveal that the presented dual band-notch monopole antenna offers a very wide bandwidth with two notched bands, covering 3.5/5.5-GHz WiMA...

A planar monopole antenna suitable for broadband wireless communication is designed and developed. With the use of a truncated ground plane, the proposed printed monopole antenna offers nearly 60% 2:1 VSWR bandwidth and good radiation characteristics for the frequencies across the operating band. A parametric study of the antenna is performed based on the optimized design, and a prototype of th...
