Summary: A fully planar single-and fixed-beam leaky wave antenna (LWA) based on leaky grounded coplanar waveguide (GCPW) is proposed in this paper. The antenna consists of a leaky GCPW, a parallel plate waveguide (PPW) prism, and a metal-strip transition. It demonstrates a fixed-beam radiation and exhibits high performance characteristics such as a peak gain of 19.4 dBi, a wide gain and impedance bandwidth, and a small beam shifting range, making it suitable for point-to-point communication applications.

Summary: This paper presents a tapered dielectric rod antenna excited by a folded dipole coplanar waveguide at terahertz frequencies. Two numerical methods are used to obtain the effective refractive index of the plasmonic transmission line and determine the dimensions of the connected gap. The antenna performance is examined for two lengths of the rod, achieving impedance bandwidths, maximum gains, and radiation efficiencies. The dielectric rod nanoantenna operates at all optical communication band frequencies and its structure includes three layers, with a silicon oxide substrate discussed for preventing direct contact.

Summary: In this communication, a novel compact single whip wideband antenna with an improved omnidirectional wideband antenna is proposed. The single whip antenna shows a wide impedance matching performance in a frequency range from 194 to 2124 MHz, while an improved omnidirectional radiation pattern is achieved by co-designing three whipped antennas. The measured performance of the fabricated antenna agrees well with the simulation results.

Summary: This paper presents a design of reflector impulse radiating antenna (IRA) with six feeding arms and a printed tapered balun that provides broadband matching to a 50 Omega system. The design is obtained through thorough numerical analysis and optimization. The use of six feeding arms results in lower input impedance while maintaining the same boresight gain as a four-armed IRA. By placing the balun in the antisymmetry plane of the antenna, the boresight gain is preserved and the antenna construction is rigid. Omitting the resistors between the arms and the reflector allows the antenna to handle at least hundreds of watts of power. The compromises made by omitting the resistors are discussed, and the results are verified through measurements of the fabricated prototype.

Summary: Metal waveguide slot array antennas are commonly used in harsh and extreme working conditions due to their high reliability, anti-interference, and power capacity. However, the fractional bandwidth of these antennas is usually not wide enough, limiting the performance of microwave systems. To address this issue, a metal slot array antenna utilizing hybrid resonant structures is proposed in this letter. The antenna has a significantly expanded working frequency band and improved performance, making it suitable for applications such as wideband satellite communication and wideband radar imaging.
