Abstract:

This paper describes the design and measured performance of very thick cylindrical monopole antennas length-to-diameter ratios about 2. These very thick monopole antennas exploit the physical dimensions of common coaxial connectors to achieve 31 frequency bandwidths with VSWR less than 21 in the 2 to 20 GHz frequency range. The antenna patterns of the very thick monopole antennas differ significantly from those of their thin counterparts. The body of revolution moment method technique is used to predict the E-plane patterns of the very thick cylindrical monopoles as those of conical monopoles at the center of finite circular groundplanes. Agreement between measured and predicted patterns is excellent.
