Ka Band Sector Horn 3D Radiation Gain Pattern Testing in Anechoic Chamber Feature

Example 9: Ka Band Sector Horn Spherical and Polar Gain Patterns

Our lab can perform measurements up through 40 GHz covering the Ku, K, and Ka bands. To highlight this capability, we have patterned a surplus WR28 wave-guide fed sector horn. Since this horn has a beam width of only 6.5 degrees in the E-plane, it was patterned with our high resolution options. The H-plane is […]

W1GHZ Dual Band Corrigated Feed Horn Antenna Pattern Testing Polar Gain

Example 5: Dual Port Corrugated Feed Horn

Our antenna testing services were used to evaluate this dual band feed horn (designed by Paul Wade W1GHZ) for amateur radio satellite use. It has orthogonal feeds for two bands, 5.8 GHz and 10.4 GHz. Testing was done in one large sweep of 5 – 12 GHz (in 25 MHz steps) to save on setup […]

RHCP Cavity Backed Spiral Antenna GPS Testing Spherical Pattern Measured in Far Field Anechoic Chamber

Example 4: RHCP Cavity Backed Spiral

This antenna test service example features full “vector” (gain with phase) circularly polarized measurements on an AEL Cavity Backed Spiral Antenna ASN112AA RHCP 1-4GHz (now made by Cobham Sensor Systems). First, standard 2D polar patterns were gathered from 1 to 6 GHz in 25 MHz steps (201 plot-able patterns) with full vector gain/phase data. Then our […]

Aluminum Planar Vivaldi Horn Antenna measured far field in anechoic chamber gain results in dBi

Antennas By RFSPACE

We love these low cost practical antennas by RFSPACE. They offer a range of interesting planar Vivaldi, LPDA, and horn antennas that are broadband and directional at reasonable prices. Their product line is being extended to some narrow-band and omni-directional broadband antennas as well. The Vivaldi Antenna (sometimes called a Tapered Slot or Vivaldi Notch) […]

Example 2: Polar Plots Of PCB LPDA Antennas

Two Inexpensive PCB Antennas Descriptions Our antenna test service evaluated two PCB antennas designed by Kent Britain WA5VJB. They are both Log Periodic Dipole Array (LPDA) antennas designed for the following ranges: Antenna “2A” Operating Range 400 – 1000 MHz Evaluated 300 – 1300 MHz (every 10 MHz, 101 frequencies) 2D polar cuts in the E and H […]

Spiral Antenna PCB for UWB Front Icon DEEPACE

Example 14: UWB Spiral Antenna

This example page showcases our circularly polarized antenna testing with swept frequency 3D patterns and a 4D gain vs frequency animation video. The antenna was purchased on eBay for $7.49 and shipped directly from China. The basic specifications were simply listed as 3 to 6.5 GHz with a gain of 3.5 dBi circularly polarized. The […]

Intruder Detection Radar Modules CDM324 HB100 RCWL-0516

Example 13: Radar Modules

Low Cost Microwave Radar Modules For 3, 10, and 24 GHz This example page showcases 3D EIRP radiation patterns for three popular consumer/hobbyist radar modules. All three are normally used for proximity sensing and intruder detection. The study of these similarly sized transmitters at 3, 10, and 24 GHz highlights the ability of antennas to […]

Example 12: Raspberry Pi Model 3B+ Antenna Evaluation

This antenna example is a common and popular option for most IoT devices operating in the 2.45 GHz “WiFi” ISM band. It is a PCB antenna designed by Proant AB and replaces the dielectric SMT chip antenna previously used the “Pi’s”. The design is a planar resonant cavity using two sets of SMT capacitors to […]

Log Periodic Spiral Antenna PCB Artwork View

Example 11: PCB Spiral Antenna

This interesting test subject by HexandFlex is a large PCB log periodic spiral antenna (not an Archimedes spiral). Its design goal was to be circularly polarized so that it would be polarization insensitive and large enough to function down to 400 MHz. The designer’s write-up of the design flow is detailed in this series of […]

Photo Measured Antenna Gain for LEO Satellite RHCP Circularly Polarized 70 cm

Example 10: Eggbeater LEO Satellite Antenna for 432 MHz (70cm)

This omnidirectional circularly polarized antenna is designed for up-facing coverage of Low Earth Orbit Satellites. It is model EB-432/RK70CM from M2 Antenna Systems. Their website description is: ” The EB-432 EGGBEATER offers exciting new performance characteristics for both fixed and mobile operations. The EGGBEATER produces smooth Omni directional HORIZONTAL polarity at the horizon. Above the horizon, the […]

First the Triple Feed Patch. The designer’s vision is: “The (center) patch has three feed pins that are fed with a 0°, […]

PCB Layout Antipodal Vivaldi Antenna With Exponential Taper Slot Edge

Example 7: Antipodal Vivaldi Antenna With Exponential Slot Edge PCB

We had the pleasure of evaluating this “pretty” antenna. It goes by the formal name of an antipodal PCB Vivaldi antenna with exponential slotted edges. Although, it is better known as a Palm Tree antenna! This design is by Iain, the author of the HexAndFlex Blog. Our antenna testing services were used to evaluate this […]
