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. WiFi Antenna | High Gain 802.11 Omni Wireless Antenna Vertical Omni-Directional 15 dB Omni Directional Antenna The 15 dB Omni wifi antenna, is a professional grade 2.4 Ghz high gain non directional radiator. It is the highest gain Omni wifi antenna that we offer, and shows gain in excess of 15dB. It is a larger antenna, almost 6 feet in length. High Gain Omni for MURS and 2-Meters - jedsoft.org

Abstract: A coplanar waveguide (CPW) center-fed four-arm slot sinuous antenna is introduced in this letter. The antenna demonstrates broadband characteristics in terms of its split-beam radiation pattern and angle of maximum gain as well as multiband characteristics in terms of axial ratio (AR), omnidirectionality, polarization, and return loss. Slot Antenna Images - International Journal of Antennas ... The gain of the sinuous slot antenna with reflector is increased from 4.6 to 9.5 dB between 4 GHz and 9.6 GHz.

appreciable increase in gain. The resulting complete antenna isverythin,makingmountingmucheasier.Notwithstanding its better behavior, little research has been carried out for slot-sinuous antennas [18–20]. This paper is focused on the design of three four-arm sinuous antennas, enabling polarization agility if backed
Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. ... Although the patch antenna needs high gain RTDs due to ... Spiral Antennas - Antenna Theory Spiral Antennas. This means that if the lower frequency is 1 GHz, the antenna would still be efficient at 30 GHz, and every frequency in between. Spiral antennas are usually circularly polarized. The spiral antenna's radiation pattern typically has a peak radiation direction perpendicular to the plane of the spiral (broadside radiation). Design of an Ultra-Wideband Spiral Antenna for Ground ...
