Slot and dipoles as dual antennas

The present invention is directed toward a dual linear or circular polarized antenna comprised of two orthogonally linearly polarized radiative elements. More specifically, the present invention is for a slender slot-dipole antenna, where the slot and the dipole are located in the same physical structure. Feed line interference to the antenna can be eliminated by including a centrally located Broadband UHF Slot Antenna - Jampro Antennas Inc. The True and Tested Prostar broadband UHF slot antenna, available for combined Analog & Digital applications. Eliminates the need for multiple antennas.

Dual-band slot-coupled dipole antenna for 900MHz and 2.45 GHz ... In [57], a dual-band slot-coupled dipole antenna operating at 900 MHz and 2.45 GHz is also presented. In [58], the design of a simple microstrip fed folded strip monopole antenna with a protruding ... THE (VHF) DIPOLE ANTENNA - G-Portál THE (VHF) DIPOLE ANTENNA At VHF and UHF, most antenna systems are derived from the dipole or its complement, the slot antenna. Many antennas are based on half-wave dipoles fabricated from wire or tubing. The feed point is usually placed at the centre of the dipole, for although this is not absolutely necessary, it can help prevent Dual-Band Slot Dipole Antenna Fed by a Coplanar Waveguide
