Design of Short Axial Length High Gain Dielectric Rod Antenna

A novel design of dielectric rod antenna is presented here. Compared to the conventionally used tapered dielectric antennas, this configuration is capable of producing higher gain for a given length of the antenna. The design of an antenna using the new configuration having a gain of 16.7 dBi at 5.6 GHz is discussed. The length of this antenna is 2.3 , which is considerably less compared to the conventional design. The material used for the antenna is Teflon. Along with the detail simulated results, the measured results of the fabricated prototype antenna are also presented.
