Broadband meanderline slot spiral antenna

slot spiral antenna to explain its broad-band characteristics. The total electrical e–ciency and peak realized gain of this slot were compared with those of a rectangular slot which is the current slot shape used in SWASS. The gain patterns from an optimised spiral shape slot were simulated and conflrmed by measurement. 2.

Ground plane meandering in Z direction for spiral antenna An antenna has a spiral driven element that meanders in a z direction, perpendicular to the x-y plane of the spiral, and a ground plane that also meanders in the z direction, such that spacing between the ground plane and the driven element is an odd multiple of one-quarter wavelength, along at least a portion of the length of the driven element.

A new broadband, cavity-backed slot spiral antenna is proposed. It combines variable growth rates at the centre region for improved high band radiation, with meandering in the outer turns for more efficient low band operation. A detailed characterisation of all antenna components and parameters is...

A Cavity-Backed Broadband Circularly Polarized Slot/Strip Cavity-backed slot antennas have two major advantages over cavity-backed wire antennas, such as dipole, helix, and spiral [1]. First, a slot antenna can be flush mounted on a metal surface; therefore, it is suitable for applications in mobile communication and radar systems of high-speed vehicles or aircraft [2]. Second, slot antennas can be easily NOVEL RECTANGULAR SPIRAL ANTENNAS - Ana Sayfa NOVEL RECTANGULAR SPIRAL ANTENNAS A Thesis Submitted to antennas can be used as a separate component antenna or as broadband feeds for reflector type dish antennas. ... for slot versions of geometry B and C to prove large impedance bandwidth of the antennas. Measured wideband S11 results were compared with those of simulation Spiral antenna - Wikipedia In microwave systems, a spiral antenna is a type of RF antenna.It is shaped as a two-arm spiral, or more arms may be used. Spiral antennas were first described in 1956. Spiral antennas belong to the class of frequency independent antennas which operate over a wide range of frequencies. Polarization, radiation pattern and impedance of such antennas remain unchanged over large bandwidth. The broadband, shallow, reflecting cavity-backed slot
