Distributed Antenna Systems (DAS) are used to provide strong and reliable wireless connectivity in location where connectivity is a problem with standard wireless routers or cellular connectivity. This app note discusses the use of DAS for IoT, cellular and other wireless applications.
Ensuring maximum power transfer between an antenna and transmitter/receiver circuitry requires impedance matching of HF components in the antenna design. This app note describes the design and matching of a 60 GHz printed antenna.
This application note describes the process of a simple antenna for LTE band operation added to the PC board of a smartphone in XFdtd being tuned for operation in multiple frequency bands. The component values in the matching network are chosen so that system efficiency is maximized.
A problematic base station can be replaced, but a cable and antenna system is not so easy to replace. This article covers fundamentals of cable and antenna analysis measurements: return loss, cable loss, and distance-to-fault (DTF).
A.H. Systems offers the series of Octave Horn Antennas comprising octave bandwidth pyramidal horn antennas with excellent half power performance. With low VSWR, high input handling capability and rugged design make this horn antenna excellent for both immunity and emissions testing.
RFMW has designed and supported the new Southwest Antenna part numbers 1009-035 and 1009-037. These antennas are designed for use in in base station infrastructure applications, and MIMO/MANET and Mesh network radios. The antennas come complete with hardware for mounting to one or two inch diameter poles enabling rapid deployment of networks for event management and security.
Laird Connectivity offers the new Revie Flex (EFF692SA3S) flexible PCB antenna for use in LTE CAT M1 and NB-IoT devices. The antenna operates within the 698 – 875 MHz and 1710 – 2500 MHz frequency ranges and is optimized for use when mounted to plastic via the supplied adhesive backing.
A.H. Systems offers the ATU-514 “non-magnetic and non-reflective” antenna tripod designed especially for use in compliance testing.
MP Antenna offers the 08-ANT-0899 multi-polarized NMO-mount antenna operating from 2 to 3 GHz for mobile data communications applications, such as for WiFi, WIMAX, and all 802.11 wireless systems in vehicles. This low profile antenna provides unequalled wireless communication in “real world”, non-line-of-sight (NLOS) environments.
The ANT-SGA Standard Gain Horn Assemblies from NSI-MI are designed to deliver accurate and reliable antenna gain measurements in antenna test range applications. These horn antennas are available to cover the 0.35 to 170 GHz frequency range.
SunAR, formerly Sunol Sciences Corporation, offers a family of Directional Antennas designed for transmitting and receiving wireless communications signals for broadband wireless, EMC testing, signal monitoring and detection, and MIMO applications. Each antenna features broadband characteristics and an innovative design enabling them to operate over wide frequency ranges with constant gain and long-lasting strength and performance.
A.H. Systems' designs, manufactures and delivers high performance Loop Antennas for a wide range of magnetic field testing. Whether used in a set to measure shielding effectiveness per MIL-STD 285 and NSA 65-6 or individually to satisfy specific requirements, the Loop Antennas are an efficient, low cost solution.
Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University's Brown School of Engineering. They're also tougher, more flexible and can essentially be painted onto devices.
Pharad has introduced a new Unmanned Air Systems (UAS)/Drone antenna based on its proprietary Peel & Stick Appliqué antenna technology.
Groundbreaking innovations on antenna technology, based on a collaboration between Lockheed Martin Space and Penn State, are now under consideration for use in the next generation of GPS satellite payloads.
