Example 15: Quad Ridge Dual Polarized Vivaldi Horn

This interesting eBay find is a Teflon PCB dual polarized Vivaldi pair.  It was specified in its listing as 698 to 6000 MHz for mobile phone testing. With dimensions of 100x100mm, we suspected it was too small to work at 700 MHz, but the Teflon PCB material hinted at microwave performance.  We tested this antenna […]

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 […]

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 […]

Example 10: Eggbeater LEO Satellite 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 […]

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 […]

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°, […]
