Broadband meanderline slot spiral antenna | Request PDF Request PDF on ResearchGate | Broadband meanderline slot spiral antenna | A new broadband, cavity-backed slot spiral antenna is proposed. It combines variable growth rates at the centre region for IET Digital Library: Broadband meanderline slot spiral antenna 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 BROADBAND VHF-L BAND CAVITY-BACKED SLOT SPIRAL ANTENNA Slot spiral antennas offer the possibility for very thin and conformal designs. This report covers the physical characteristic of a cavity-backed slot spiral, as well as the associated infinite balun and termination designs.

A rectangular slot antenna fed by microstrip line is proposed, which produces a very large bandwidth on a relatively thin substrate. Simulated and measured results show that there is an improved bandwidth, a relatively stable pattern and that its fabrication is easier than that for the conventional slot antenna. US Patent for Periodic spiral antennas Patent (Patent ... In one embodiment, a periodic spiral antenna includes first and second arms that form interleaved spirals parallel to an x-y plane, wherein the arms have a height dimension that extends along a z direction that is perpendicular to the x-y plane, and wherein the interleaved spirals form multiple turns of the antenna, the turns being equally spaced from each other throughout the antenna.

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.
US5815122A - Slot spiral antenna with integrated balun and ... A slot spiral antenna with a planar integrated balun and feed. The slot spiral is produced using standard printed circuit techniques and comprises a dielectric substrate having a conductive layer which is etched to form the radiating slot spiral. An integrated microstrip feed is included to provide a balanced feed to the slot spiral.
