Abstract:

This paper presents for the first time low-profile, electrically small antenna with omnidirectional vertically polarized radiation similar to a short monopole antenna. Planar antennas capable of producing vertical polarization have long been sought for many military applications. The paper discusses two distinct and novel techniques that are facilitated to devise antennas that are small as 0.01 lamba in vertical height and perfectly matched to a 50 ohm source without the need of an external matching network. The antennas are designed, fabricated and measured. Additional studies are performed for further size reductions and performance improvements.
