“…Although, the Vivaldi antenna has compact size at MMW frequency band, the efforts are being made to further reduce its overall dimensions . It can be observed, while achieving compact dimensions of MMW antenna other performance parameters, such as bandwidth, gain, radiation efficiency, and spatial dispersion, have also been compromised .…”

Broadband antipodal Vivaldi antenna (AVA) for radio over fiber (ROF) applications is presented. Comprehensive analysis based on several full wave simulations is performed to finalize a compact AVA design having physical dimension of 32 × 30 mm2. The measured results demonstrated that proposed antenna can be operated from 14.8 to 67 GHz band showing 128% fractional bandwidth. The designed antenna presents pulse fidelity factor (PFF) value equal to 0.95 for the transmission of ultrashort time duration pulses having full‐width‐half‐maximum (FWHM) of 7.6 ps. An experimental ROF measurement setup is developed with our proposed AVAs and light‐wave component analyzer (LCA) operating over 15–40 GHz. For ROF measurements, PFF value equal to 0.94 is confirmed. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1441–1446, 2017

“…In recent years, with the rapid development of the wireless communication system, broadband and high gain has become two important factors in the design of UWB antennas . Tapered slot antenna (TSA) is one of the best antenna used in ultra‐wideband technology, which was first proposed by Hines et al in 1953, and it is widely used in radio astronomy, ground penetrating radar, ultra‐wideband communication, ultra‐wideband imaging, and other fields . The TSA has the advantages of simple structure, easy processing, and good port matching.…”

In this article, a novel double‐slot linearly tapered slot antenna with conformal corrugated edges, is proposed. By using double‐slot structure, the E‐plane aperture field of the proposed antenna is more like a plane wave, which helps to improve the directivity of the antenna. Meanwhile, a novel corrugated edge is designed. This conformal corrugated edge can cover all the outer edges of the antenna which has a better improvement of the impedance bandwidth compared with the rectangle corrugated edge. Additionally, according to the theory of microwave network, this article analyzes the reason of bandwidth enhancement realized by double‐slot structure. The proposed antenna provides 145% fractional bandwidth from 3.5 GHz to 22 GHz. The gain of the proposed antenna is more than 12 dB from 6.5 GHz to 21 GHz, and more than 8 dB at the whole operating band.

This work presents an analysis of the effects of a hybrid linearexponential tapered slot on the key properties of both the antipodal and co-planar Vivaldi antennas at low frequencies using parametric analysis and Nonlinear Sequential Programming optimisation. It was observed that the hybrid tapered slot can extend the lower frequency limit of the antipodal Vivaldi antenna however with slight deterioration of the gain and E-plane radiation pattern. On the other hand, the optimisation of the hybrid and conventional tapered slot co-planar Vivaldi antennas converged to antennas with the same performance results.
