Slot line fed planar dipole antenna with a parasitic strip for wide ... In this section the use of the slot line to feed a dual band antenna and a dipole is discussed. 1. Introduction Dipole antennas are attractive for wireless applications due to a host of applications like simple design, excellent radiation pattern etc. Normally printed dipoles are excited using a microstrip line [1-3]. Recently uniplanar dipoles have received wide attention due to advantages like ease of fabrication and integration of active circuit elements [4-5]. Most of the reported ... Slot Antenna
How does a slot antenna work? - Stack Exchange
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-polarized antennas are widely used in radio frequency communication systems, especially in mobile cellular base stations. Compared to linearly polarized antennas, dual-polarized antennas are more attractive because they can combat the multipath fading and increase the channel capacity .
