Summary: This paper proposes a wideband three-dimensional isotropic antenna with improved 3 dB coverage ratio. By investigating the impact of metallic ground size on isotropic radiation, a compact sequential-phase feeding network made of lumped components with miniaturized ground is elaborately designed to achieve wide operating bandwidth and enhanced 3 dB coverage ratio in 3-D space. The measurement results demonstrate that the proposed antenna provides a 6 dB gain variation fractional bandwidth of 4% and a 3 dB coverage ratio of more than 80%, indicating promising potential for wideband isotropic radiation applications.

Summary: In this study, a size-reduced 15-element Yagi antenna implemented in a planar shape with T-shaped top loadings achieved a 45% reduction in element lengths compared to a traditional lambda/2 full-sized Yagi antenna. The proposed antenna showed a similar bandwidth and realized gain compared to the full-sized Yagi antenna. Additionally, a minor difference in realized gain was observed when more than two parasitic elements were added, with approximately 0.2 dB contribution per added element. The measurements and simulations were in good agreement.

Summary: This paper proposes an ultrawideband planar monopole array antenna with excellent stealth performance by using a combination of traditional copper film and novel phase transition film vanadium dioxide (VO2). By carefully designing the antenna shape and using an innovative combination of VO2+Cu films, the tradeoff between radiating efficiency and reducing radar cross section (RCS) is optimized, resulting in a decreased gain of only 0.4 dBi and a reduced monostatic RCS of about 9 dB.
