Broadband circular polarised logarithmic periodic spiral antenna CLSA 0110 offers circular polarization over approximately one decade up to microwave frequencies. The antenna can be used for both receive and transmit applications.
Please specify the direction of polarization when ordering: Right Hand Circular Polarization (RHCP) or Left Hand Circular Polarization (LHCP).
Linear polarized fields can also be covered by this antenna without the need to arrange horizontal and vertical polarization separately. When operating with linear polarized fields, the antenna factor must be increased by 3 dB, and the gain must be reduced by 3 dB to obtain correct readings.
