“…UWB antennas with 6-18 GHz bandwidth is important in radar and satellite communication among which Vivaldi antenna is known as a best choice for this aim with various shapes of the radiator and dielectric lenses for improving the radiation [26][27][28][29][30][31][32][33][34][35][36][37][38][39]. The final prototype antenna shows good performances in this range and it also covers 5-22 GHz for wideband experimental test as shown in Fig.…”

Controlling of the phase centre in ultra wideband antenna is important in localisation at radar systems as for accurate localisation, a constant or linear phase centre is required. In addition, high gain, high bandwidth and end‐fire pattern are demanded in these systems. Therefore, end‐fire taper slot Vivaldi antenna has been noticed because of its high gain and wide bandwidth and end fire pattern. The authors have suggested utilising photonic band gap (PBG) for making a linear phase centre of the antenna. Implementation of the PBG substrate has controlled the electric field and surface current over the antenna and compensated the distortion in phase centre and in addition improved the mutual coupling in the proposed antenna. Here, for achieving best results the parametric studies have been noticed for PBG hole diameters and arrangement of these elements is investigated studied. Furthermore, using PBG substrate has improved the antenna gain. The final prototyped antenna with PBG substrate in order to work in a wide bandwidth shows acceptable performance in the range of 6–18 GHz with VSWR <2 antennas well as achieving a higher gain of >2–4 dBi and >90% efficiency, in comparison with conventional tapered slot antennas.

In this study, the design and simulation of a circularly-bended antenna array at X-band for satellite applications is presented. Antipodal Vivaldi Antenna (AVA) is selected as an array element due to its wideband and end-fire characteristics. The proposed antenna, operating in the 8-12 GHz frequency range, provides good VSWR and high gain without degradation of radiation pattern caused by conforming operation. The design is intended to be used to in both satellite and ground systems with beam scanning capability.

In this paper, a frequency reconfigurable Vivaldi antenna with switched slot ring resonators is presented. The principle of the method to reconfigure the Vivaldi antenna is based on the perturbation of the surface currents distribution. Switched ring resonators that act as a bandpass filter are printed in specific positions on the antenna metallization. This structure has the ability to reconfigurate between wideband mode and four narrow-band modes which cover significant wireless applications. Combination of the bandpass filters and tapered slot antenna characteristics achieve an agile antenna capable to operate in UWB mode from 2 to 8 GHz and to generate multinarrow bands at 3.5 GHz, 4GHz, 5.2 GHz, 5.5 GHz, 5.8 GHz and 6.5 GHz. The measurement and simulation results show good agreement. This antenna is an appropriate solution for wireless applications which require reconfigurable Wideband multinarrow bands antenna.
