A Compact Modified Square Printed Planar Antenna for UWB Microwave Imaging Applications
نویسندگان
چکیده
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 radiation pattern, transmission coefficient and system fidelity factor are very satisfactory. Moreover, by fabricating and testing the proposed antenna, the simulation results are fairly verified. Keywords—Modified square planar antenna; high bandwidth; return loss; UWB antenna; low profile; frequency and time domain analysis

UWB Planar Conical Horn-Shaped Self-Complementary Bow-Tie Antenna
An ultra-wideband (UWB) self-complementary planar bow-tie antenna (SCPBTA) is proposed. The antenna consists of a printed conical horn-shaped (CHS) radiator and a counterpart CHS slot etched on a rectangular ground plane. The printed CHS radiator is connected directly to the 50Ω microstrip line by bending the end portion of the feed line. As a result, the antenna has a simple structure which do...

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...
