Full Title

Full titles differ between systems:

IPC:

Combinations of primary active antenna elements and units with secondary devices, e.g. with quasi-optical devices, for giving the antenna a desired directional characteristic > using a secondary device in the form of two or more substantially straight conductive elements > the primary active element being end-fed and elongated

CPC:

Combinations of primary active antenna elements and units with secondary devices, e.g. with quasi-optical devices, for giving the antenna a desired directional characteristic > using a secondary device in the form of two or more substantially straight conductive elements (log- periodic antennas H01Q11/10; constituting a reflecting surface H01Q19/10) > the primary active element being end-fed and elongated
