A Compact Tri-Band Horizontally Polarized Omnidirectional Antenna for UAV Applications

Performance-Issues-Mitigation-Techniques for On-Chip-Antennas – Recent Developments in RF, MM-Wave, and Thz Bands With Future Directions

“…Internet-of-Things is another prominent emerging application, which makes use of low-frequency bands [156]- [160]. Biomedical implants [161]- [163], wireless sensor networks [164]- [167], unmanned aerial vehicles [168]- [170], and wireless energy transfer [171]- [174] are some other vital applications, which operate in RF and microwave bands. Although a number of AoCs have been designed in RF and microwave bands as listed in [45], the use of performance enhancement methods for these AoCs is scant as evidenced by Table 1 of the paper.…”

Low Gain Ripple and DC-Grounded Slant-Polarized Formulation With 360° Broadbeam Coverage

“…The optimized geometric parameters are summarized in Table.1 For Military operations, antennas should be able to move towards remote, rough, and tough operational area terrains and bear all-weather conditions. Such requirements require the potential antenna must be physically rugged and robust structure and requiring no external spine to support as exterior spines make these antennas bulky [33]. Large antennas also induce more drag, which increases the chances of damages due to turbulent weather conditions and too weak from a structural point of view [33,34].…”

A 3D-Printed Tapered Cavity-Backed Flush-Mountable Ultra-Wideband Antenna for UAV

“…2 (c) illustrates an antenna with exponentially tapered cavities (ANT3). Because the tapering profile mitigates the impedance mismatch at the cavity wall, an electromagnetic wave generated inside the exponentially tapered cavities propagates with little reflection at the outer region of the cavity, resulting in a low reflection coefficient of the antenna [8]. Fig.…”

“…It is small and lightweight, and has omnidirectional characteristics in a wide frequency band. In [8], the researchers proposed a tri-band, horizontally-polarized omnidirectional antenna combining a folded tapered patch and a vertical slot together inside the The associate editor coordinating the review of this manuscript and approving it for publication was Diego Masotti . rectangular cavity.…”
