AN OVERVIEW OF CONFORMAL ANTENNA DESIGN TECHNIQUES USEFUL FOR TELEMETRY APPLICATIONS

Abstract

Several conformal antennas useful for telemetry applications are described. These antennas make use of dielectric-loaded cavity, edge-slot, microstrip, and dielectric rod radiator design techniques. Critical design parameters, modes of radiation, and theoretical considerations are discussed, as well as intrinsic properties and characteristics of the dielectric materials used. Experimental data relating to impedance, gain, polarization, and bandwidth are given. Also presented are prototype telemetry antennas and performance characteristics. The conformal antennas are flushmounted and designed as an integral part of the body structure. These antennas are electrically small and compact, occupying minimial space. They can be designed efficiently for operation in the telemetry frequency band to produce the desired radiation pattern coverage. Simplified construction and low cost are among the other advantages realized.
