CPW-fed ultra-wideband slot antenna with broadband dual ... To better explain the antenna design, Fig. 2 shows four evolution stages of the antenna. Initially, a square slot antenna with two CPW-fed ports are depicted as shown in Ant.1 of Fig. 2. It provides two operating bands at around 3.8 and 15.6 GHz with narrow impedance matching and only has linearly polarized feature. Ultra‐wideband square‐slot antenna | Request PDF A simple square-slot antenna capable of providing a very wide impedance bandwidth of larger than 9 GHz is presented. The ultra-wideband operation for the proposed antenna is realized by using a ...
An ultra‐wideband (UWB) square slot antenna with a band‐notched characteristic is presented. The proposed antenna has a simple configuration and is easy to construct. The ultra‐wideband operation is realized by loading an offset rectangular stub at the end of

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).
