Abstract— Study of a novel planar circular disc monopole ultrawide-band antenna fed by coaxial line is presented in this paper. The radiator, ground plane and the feeder equipment of the antenna are placed on the same plate. The special structure reduces the spatial volume, and it is used to realize the miniaturization of the antenna. The basic theory and design method are analyzed, and detaile...

body centric wireless communication (bcwc) has been the topic of much research in recent years. in this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communications with a dual-band operation. the proposed structure exhibits a monopole-like radiation pattern at 2.45ghz and a broadside radiation at 4.8ghz, simultaneously. lateral dimensions of 42 mm × 46 mm a...

In this paper, we have investigated printed rectangular monopole antennas, which is basically a printed microstrip antenna with etched ground plane for multi-band applications. In particular, we have fabricated and tested printed rectangular monopole antennas for dual-band and penta-band applications. It has been observed that printed rectangular monopole antennas are small in size and simple i...

This paper describes the design of the disk-loaded monopole with a parasitic array for beam switching. Usually the radiation pattern of a single element such as a λ/4 monopole and the disk-loaded monopole provide low values of gain. The beamwidth is normally large and the coverage is wide. This may be appropriate in an on-body channel where the antenna orientation may not be easily controlled, ...

The complex antenna factor (CAF) introduced to measure transient electromagnetic fields or electromagnetic pulses and its applications are investigated. The equations of the three-antenna method for determining the CAF of a dipole antenna, a log-periodic dipole array antenna (LPDA), and a monopole antenna are derived. The results of the waveform reconstructions using the CAF are compared with t...

Manuscript Received 4-June-2012 and revised 18-September-2012 ISSN: 2322-3936 Accepted on 1December-2012 Abstract—This paper presents a new approach for the design of a multiband uniplanar CPW-fed monopole antenna. The antenna consists of a fork like monopole strip to which is added an inverted U-shaped strip. The three branch fork like strip can create three resonant bands within the WLAN rang...
