ANT05380 6-18G Planar Spiral helical antenna

A description of the ANT05380 6-18GHz Planar Spiral Antenna:

Leader-mw ANT05380 is a sophisticated planar spiral antenna operating across an extensive 6 to 18 GHz frequency band. This passive, ultra-wideband antenna is engineered for high-precision applications where robust performance in a compact form factor is essential. Its design, featuring a printed spiral element, ensures consistent gain and radiation properties across the entire bandwidth.

This antenna is a premier sensor for use with advanced test monitoring receivers and spectrum analyzers. Its primary function is in Electromagnetic Compatibility (EMC) testing and Signals Intelligence (SIGINT), where it excels at accurate field strength measurement of complex or fleeting signals. The antenna's stable phase center and symmetrical radiation pattern make it an ideal candidate for multi-antenna direction-finding (DF) systems, capable of determining the precise incident direction of radar and communication signals.

A key attribute of its spiral design is its inherent frequency-independent circular polarization. This allows it to efficiently receive signals of any linear polarization and is particularly valuable for analyzing and characterizing the polarization of unknown emissions, a critical capability in modern electronic warfare (EW) and threat identification scenarios. Its wideband coverage makes it a single-antenna solution for a vast range of microwave frequencies.
