The 2020 Chevrolet Impala: the last full-size sedan produced by Chevrolet before its discontinuation.
Abstract: This paper presents a compact, wideband, circularly polarized (CP) antenna array for terahertz (THz) applications using low-temperature co-fired ceramic (LTCC) technology. The CP radiation ...
Abstract: Reducing size and sidelobe level (SLL) is essential for a resonant cavity (RC) type antenna. This communication proposes a PRS-less RC antenna with compact size, low profile, and sidelobes.
The antenna must adhere to more stringent requirements, including multi-band operation, high performance, and compact design, since it is the primary component of satellite communication systems. A ...
First, there's a thread from 2024 that might still be relevant. My situation is that I just cut the cable TV cord, but I want all the local OTA channels to come in well, ideally (for now) into my ...
The year 2025 ended with more than 14,000 active satellites from all nations zooming around the Earth. One-third of them will soon move to lower altitudes. The maneuvers will be undertaken by SpaceX, ...
