Abstract
In this thesis, a high directivity active horn antenna is designed and analyzed, and which is implemented by integrating the horn antenna, dielectric resonator and power amplifier. Using DRs in the stripline-to-waveguide transition, signals can couple to stripline or waveguide efficiently. An 8 \% impedance bandwidth and better radiation patterns in the $E$-plane radiation is observed. By integrating power amplifiers into the horn antenna, antenna gain is increased by 7.1 dB without increasing the circuit volume. Chokes are used to reduce the backward radiation. Finally, dual horn antennas are designed and implemented. Sum and difference patterns are also observed as expected. The invention can be applied in many fields such as satellite communication, short term communication, microwave detection system, and signal detector, etc. They can be moduled for extensive application.
