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

1268. Circularly Polarized Slot Antenna for wireless Applications. This novel presents an Ultra wideband circular polarized slot square antenna. (CPSSA), which ...

The Vivaldi Antenna My chosen antenna design is a version of the Vivaldi antenna.This was achieved by cutting the end of the PCB into an arc rather than leaving it square.12 comments on “Making an Ultra-Wideband Antenna – Part 2 (Introducing the Palm Tree Vivaldi Antenna)”. Advancement in Ultra Wideband Antennas for Wearable… Various Ultra wideband antennas have been categorized in four forms based on four corners of Figure-2 1. Multiband, Omni UWB Antennas 2The radiating element with radius of 15 mm and a rotated square slot of 6 mm x 6 mm at the centre of the circular patch was used in the paper.

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).

Mohsen Koohestani and Mohsen Golpour, Compact rectangular slot antenna with a novel coplanar waveguide fed diamond patch for ultra wideband applications, Microwave and Optical Technology Letters, 52, 2, (331-334), (2009). 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

Mechanical simulations indicate that the existence of O-slot can reduce the strain concentration on the metal layer of antenna, which enhances the flexibility of the antenna.
