PWC200 -
Rohde & Schwarz GmbH & Co. KG
The R&S®PWC200 Plane Wave Converter is a bidirectional array of 156 wideband Vivaldi antennas placed in the radiating near field of the device under test (DUT). The phased antenna array can form planar waves inside a specified quiet zone within the radiating near field of the 5G massive MIMO base station for realtime radiated power and transceiver measurements (EVM, ACLR, SEM, etc.).

Biconical Antennas have dipole like characteristics (e.g. circular directional pattern in the H-plane,"8"-shaped in the E-plane, fixed phase center, comparable gain), with an enormous wide bandwidth achieved by the double cone elements. One of the earliest and worldwide most popular biconical antenna designs is the BBA 9106 with balun VHA 9103 B. During the last years a growing need for expanded frequency ranges arised, which led to the design of biconical antennas reaching down to frequencies of 20 MHz and up to 18 GHz and above. A further increase of bandwidth was achieved with qualified 4:1 baluns, providing a typical gain increase of approx. 6 dB at the lower frequency range. The biconical elements can be mounted and dismounted within a few seconds providing perfect contact repeatability thanks to special clamping fixtures. A small wrench made of insulating material is supplied with the balun, it is tied to the balun head and thus always available whenever needed. Biconical antennas can be used for many applications, in which half-wave dipoles have been used traditionally. An enormous reduction of measurement time can be achieved, because the time consuming tuning of the antenna elements to the half wavelength is not needed, an important condition for sweeped broadband measurements. In typical dipole applications several discrete frequencies are measured, in contrast the biconical antenna allows continuous sweeps, where site anomalies are discovered much easier.

Cuming-Lehman Chambers
It’s nearly impossible to perform VHF/UHF measurements in a rectangular chamber. In the 1960’s Emerson determined that tapering one end of an Anechoic Chamber would cause the chamber to act like an indoor ground reflection range.Tapered Chambers work very well at the lower frequencies. Their design forms a uniform illumination across the test region. The tapered end of the chamber forces the wall images close together forming a source antenna array. Tapered Chambers are usually a less expensive option compared to rectangular antenna measurement chambers or compact ranges.

If you have a small PCB with a small antenna you can't use a thick cable and a large connector. Not only is this impractical (how to connect the connector?) but the metal bulk will also affect the antenna and grounding properties of your PCB. The measurement will be useless. MegiQ promotes the use of the small and popular UFL connector and its associated cables. The UFL socket fits on almost any PCB and it can be improvised on a board without a UFL footprint.

K6BEZ -
HamRadio 360
The K6BEZ antenna analyzer will provide VSWR measurements for any antenna from 1 to 30 MHz. Frequency and VSWR is shown on the built in LCD display. Data can optionally be sent over the USB cable to a PC running a program that will plot the VSWR on a graphical window display. The analyzer can be programmed to scan any sub band and has built in ranges for 160m, 80m, 60m, 40m, 30m, 20m, 17m, 15m, 12m, 10m.

iP60z -
iPortable
The new iP60z iPortable™ Antenna SWR Analyzer is designed for field use. This compact battery powered unit has an easy to read frequency display and measures SWR and impedance in the HF Band and VHF 6 Meter band. The SWR readings quickly show you the actual VSWR measurement and Magnitude of the impedance (Z). This is the easiest way to adjust your portable or base station antenna to be best matched for your radio.

EFS-105 -
enprobe GmbH
The EFS-105 is the first in a family of fiber-optic active antennas & E-field probes. The field distortion caused by the probe head is nearly zero due to the exceptionally small probe head and the all-optical signal transmission and power supply. This gives an invaluable advantage for near field measurements and measurements close to metallic parts.

MegiQ BV
The unbalanced interface of a VNA is not very well suited for measuring balanced circuits like antennas, transmission lines or chip impedances. In fact it is nearly impossible to get a decent calibration on a balanced 2-port measurement using coax cables.
