Designing an Ultra Wideband Vivaldi Antenna The Vivaldi is a fairly well known ultra wideband antenna that is directional. It is fairly easy to build out of a PCB board, but requires some careful design considerations to work well. In the second post hexandflex goes over all the design considerations that he put into his Vivaldi incliding the feed design... Introduction to ultra-wideband antennas A wide variety of antennas are suitable for use in ultra-wideband applications. Some of these are described elsewhere in a historical survey [1]Figure 4: The continuously tapered slot horn elements of Nester (gray colorization on elements added). Calculating the impedance of a slotline horn requires... Ultra-Wideband Antennas | Cobham Antenna Systems

ABSTRACT In this paper a microstrip-fed ultra wide-band (UWB) printed monopole antenna with frequency band-notch characteristics is proposed. The proposed antenna has a size of 12mm x 20 mm. The antenna comprises of a π shaped slot on square radiating patch placed on FR4 substrate.

EUMA By introducing an L-shaped metal plate connecting with the spiral monopole antenna, a planar compact ultra-high-frequency (UHF) tag antenna for radiofrequency identification system is proposed.

studied a special square slot antenna for circular polarization, which is composed of a square ground plane embedded with two unequal-size inverted-L strips around two opposite corners of the square slot. The antenna owns an impedance bandwidth ratio of 4.7:1 (2.67~13 GHz) and a circular polarization bandwidth ratio of 1.5:1 (4.9~6.9 GHz).
