In this paper, both frequency and time domain performances of a new compact planar antenna for the ultrawideband (UWB) applications are fully investigated. The proposed antenna has the size of 12x18 mm2 providing a fractional bandwidth more than 128123% (3.057 GHz to 13.98 GHz, S11<-10 dB). The results show that the proposed antenna performances in term of wide bandwidth, small size, gain and r...

This paper gives information about construction of planar rectangular monopole antenna on Printed Circuit Board (PCB). Behaviour of such planar antenna is same as the rectangular patch antenna with finite ground plane which lies in same plane of given PCB. The designed antenna is a broadband antenna as its ratio bandwidth falls under broadband category. In comparison with monopole antenna broad...

In this paper a novel structure of metamaterial is proposed in order to miniaturize a rectangular microstrip patch antenna. The metamaterial is composed of two nested split octagons which are located on a 10 mmx10 mm Rogers RT/duroid 5880 with 0.7874 mm thickness and dielectric constant of 2.2. A 3X5 array of such metamaterials is placed on the patch antenna substrate. By using this metamateria...

A double-discone antenna for an ultra-wideband frequency scan is presented. An exquisite assembly of two inverse-feeding discone antennas shows a 30:1 broad bandwidth with VSWR below 2.5 and an omnidirectional radiation pattern. These features make the proposed antenna very suitable for both the UWB system antenna and the wideband scan antenna. © 2004 Wiley Periodicals, Inc. Microwave Opt Techn...

Abstract—The limitation of the pulse repetition frequency (PRF) of an airborne synthetic aperture radar (SAR) system is not a serious problem to obtain high azimuth resolution and wide swath imaging compared with a spaceborne SAR system. Hence, continuous high azimuth resolution imagery over a wide area can be obtained using an antenna having a wide beamwidth. Since a small antenna with a large...
