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 […]

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 […]

Photo 1 Pagoda 2 FPV LHCP Measured at Antenna Test Lab Co

Example 6: LHCP Omnidirectional FPV Antenna

This Example Test Report features a small LHCP omnidirectional antenna designed by the talented Maarten Baert. It is a sophisticatedly simple design with three PCBs on a semi-rigid coax and an SMA connector. This inexpensive antenna was designed for the 5.8 GHz WiFi market, targeting FPV (first person view or remote person view) drone control transceivers. When […]

small-PCB-Layout-Antipodal-Vivaldi-Antenna-With-Exponential-Taper-Slot-Edge

Example 7: Antipodal Vivaldi with Slot Edges

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 […]

con-Antenna-Test-Lab-Triple-Feed-Patch-Array-With-LHCP-RHCP-Ports

Example 8: Triple Feed Patch Array CP Antenna

Here are vector gain test results of  Maarten Baert’s  latest circularly polarized 5.8 GHz antenna. There are two versions covered here: a CP Triple Feed (single) Patch and a Triple Feed Patch Array. First the Triple Feed Patch. The designer’s vision is: “The (center) patch has three feed pins that are fed with a 0°, […]

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

Example 9: Ka Band Sector Horn

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 […]

Raspberry Pi Antenna Radiation Patterns

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 […]

Example 2: Polar Plots of PCB LPDAs

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 […]

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) […]
