Low cost linear/circularly polarized antenna |
摘要 |
A linear/circularly polarized antenna system is provided by four conductive elements. The conductive elements are joined in pairs at their ends with the joined ends spaced by a conductive support member from a flat reflector. The lengths of the conductive elements of each dipole element are changed from being equal lengths of approximately a quarter operating frequency wavelength to one slightly longer and the other slightly less than a quarter wavelength to selectively change operation from that of a linearly polarized antenna to that of a circularly polarized antenna.
