Radio Direction Finding Antenna for VHF: I needed an antenna to chase down a noise source.. After much ado I settled on some plans I found on the web, added my own modifications \u0026 took some photos along the way. It has a cardoidal pattern with a deep null on the rear. I made a few mino…

Antennas Direct Enhanced Multidirectional Bowtie Attic Outdoor Antenna

Antennas Direct Enhanced Multidirectional Bowtie Attic Outdoor Antenna With an extended range of over 70 miles and unsurpassed gain of 17.4 dBi, this multi-directional bowtie antenna has specially designed brackets that allow it to turn in a 180º loop, to target transmitting towers in any direction. The patented design enables the DB8e to target specific, core digital TV channels. It’s the ideal choice for rural and suburban installation challenges, designed to pull signals in through heavy foliage, or roofing materials when located in the attic. It’s easy to install, with placement options that are not possible for larger antennas. What You Get Bowtie/attic outdoor antenna Mounting brackets Manufacturer’s lifetime limited warranty (1-877-825-5572) Good to Know Mount and coaxial cable sold separately

MENACE Thrasher 5.8G 1.22dBi Circular Polarized High Gain Omni Directional FPV Pagoda Antenna LHCP/RHCP SMA for RC Drone Fatshark Goggle – RHCP

MENACE Thrasher 5.8G 1.22dBi Circular Polarized High Gain Omni Directional FPV Pagoda Antenna LHCP/RHCP SMA No compromise in performance, just like its bigger brothers, the THRASHER delivers a smooth radiation pattern with one of the most pr0ven highest axial ratio designs all in a cableless resilient polycarbonate case for protection.   Taking the popular pagoda antenna designed by Maarten Beart, Menace has redesigned it for the demanding FPV drone pilots, incorporating adjustments to make it compact, fully cased to avoid coax cable da

Microstrip Patch Antenna Array with Omnidirectional Pattern (Paperback)

Microstrip is the name given to a type of open wave guide structure which is now commonly used in present day electronics not only as transmission lines but for circuit components such as filters, couplers, resonators etc. They have some well-known advantages such as small size, lightweight, low profile and low cost.This work had a broader scope of analysis, design, fabrication, testing and implementation of aperture coupled microstrip patch antenna array with omni-directional pattern. An aperture coupled microstrip antenna used aperture coupling and does not require a direct connection between the patch and the feed line. A small aperture in the ground plane located under the patch allows coupling from the feed line.The feed network requirement for the array to the required amplitude distributions has been addressed. Typically, these arrays of microstrip antennas are used to reduce overall ripple in the roll pattern of the antenna. This entire project has been carried out in LRDE, DRDO, Bangalore.
