The antenna element with rectangular aperture is one of the main forms of the array antenna. The electric field amplitude distribution of the rectangular aperture, as well as the phase distribution is the most important parameter that affects the radiation gain and beam direction of the array antenna. In this work, a theoretical study is carried out on array antennae for high-power microwave (HPM) applications. An electric integration method is applied to obtain the far-field radiation pattern with different kinds of electric field distributions. Moreover, the influence of the electric field amplitude and phase on the performance of the array antenna is analyzed. For one antenna element, uniform electric field distribution is not the best choice. However, the uniform distribution has specific advantages for an array antenna consisting of combined antenna elements. The phase deviation has more significant influence on the performance of the array antenna than the amplitude deviation. It indicates that a good working phase shifter with high-power capacity and time-adjusting capability is very important.

Two kinds of high-power waveguide phase shifters targeting the application of phased arrays are proposed in this paper. To enhance the power handling capacity, both linear phase shifters are designed to be mechanically tunable without the introduction of a dielectric and a semiconductor. For the waveguide-inserting-fin phase shifter, the phase shifting function is achieved by adjusting the length of the inserting metal fin. As for the narrow-side slot-waveguide phase shifter, the regulation of the position of the metal choke plunger placed at the end of the 3-dB power divider is used to adjust the output phase. The simulation results show that both phase shifters can realize 2π phase shift, and the transmission efficiencies are over 99% at the central frequency of 9.5 GHz. Meantime, the power handling capacity of the designed shifters is expected to be over 100 MW, which can be applied in the high-power microwave region. The slot-waveguide phase shifter is fabricated and tested along with the slotted array antenna. The experimental results coincide well with the simulations, which demonstrates the feasibility and the power capacity of the designed shifter.
