Spiral antennas belong to the class of "frequency independent" antennas; these antennas are characterized as having a very large bandwidth. The fractional Bandwidth can be as high as 30:1. This means that if the lower frequency is 1 GHz, the antenna would still be efficient at 30 GHz, and every frequency in between. high+gain+antenna - Staples Inc. high+gain+antenna.

What is a High Gain WiFi Antenna? A High Gain WiFi Antenna is a directional antenna (such as a Yagi antenna or parabolic grid antenna) that has a narrow radio wave beam width.In addition to using a directional, narrow beam width, a high gain WiFi antenna typically features gain of 12-14dBi and greater.

Agastra et al., the authors analyze three ground-backed compact strip and slot sinuous antennas. e pro-posed con guration allows for a single lobe, polarization-versatile, high e ciency, and ultrawideband antenna not 915 MHZ INGLE ENDED ANTENNA MATRIX SELECTION GUIDE 1 ... This type of antenna is a popular, small, low-cost, wire alternative to the external whip antenna, but the gain is still slightly lower due to the shorter length. However, the gain with the medium helical antenna is much better than with the small helical antenna. This type of antenna is typically used in key fobs, set-top boxes, AMRs, and alarm
A dielectric-loaded antenna having a plurality of radiating elements and a loop element plated on the surface of a cylindrical ceramic core has balanced and single-ended modes of resonance which are coupled together so as to define an …

This type of antenna is a popular, small, low-cost, wire alternative to the external whip antenna, but the gain is still slightly lower due to the shorter length. However, the gain with the medium helical antenna is much better than with the small helical antenna. This type of antenna is typically used in key fobs, set-top boxes, AMRs, and alarm HF Skeleton Slot - An antenna system with a difference. | QRZ ... The skeleton slot antenna used to be pretty popular on 2-meters and higher frequencies. J-Beam Ltd. (an antenna company in the U.K.) used to make several different models for 2-meters with different numbers of parasitic elements. Basically, the antennas were yagis except for the feed which was a skeleton slot.
Abstract. Three ground-backed compact strip-and slot-sinuous antennas are analyzed. Proposed configuration allows for a single lobe, polarization-versatile, high efficiency, and ultrawide band antenna not needing a cumbersome lossy back cavity typical of conventional single-lobe sinuous antennas.
