“…With the development of high-power technology, the research on high-power array antennas promotes the applications for various military and civilian satellite communications [1]. The available high-power array antennas mainly focus on increasing the operating frequency [2], [3], improving the power capacity [4], [5], realizing beam scanning [6], and extending the bandwidth [7]. These technologies promote the development of high-power microwave antennas, but they can only operate in one frequency band.…”

The demand for multi-band high-power antennas, which have been rarely reported, becomes urgent in high-power microwave field. To meet the demand, a C/X dual-band high-power circularly polarized patch reflectarray antenna is proposed in this paper. Two main technologies are adopted to make the proposed antenna realize the high-power feature. Firstly, the elliptical patch with no abrupt structure is proposed to be the dual-band reflecting element to mitigate the electric field concentration. Secondly, the elliptical patches are proposed to be embedded into substrate to avoid the triple junction. The proposed dual-band reflecting element is designed by arranging two embedded elliptical patches with different sizes in a square lattice grid. The larger elliptical patch operates in C-band and the smaller one works in X-band. The elliptical patches are proposed to be rotated to realize continuous 360 o phase response in both bands. By optimizing the thickness of substrate, the element spacing, and the size of the patches, the dual-band element shows good reflection amplitude and phase response and low mutual coupling performance. An antenna prototype with the aperture size of 345 mm × 345 mm is simulated and measured. The measured radiation results of the designed reflectarray antenna are in good agreement with simulations in both C-band and X-band. The measured gain of the antenna at 6.2 GHz is 24.6 dBi, and at 9.3 GHz is 27.8 dBi. Fullwave simulations show that the power capacity of the antenna at 6.2 GHz is about 10.2 MW, and at 9.3 GHz is about 3.9 MW in air condition. The low mutual coupling performance of the proposed antenna is verified both in element level and array level. All of the results show that the proposed antenna has the merits of high-power capacity, dual-band, and low mutual coupling.

“…Because of its function of focusing microwave generated by microwave source and radiating for specific target, its performance largely determines the overall working characteristics and application of HPM system. So far, a large number of scholars have proposed various forms of HPM antennas [3][4][5][6]. Among them, due to its high power capacity, low profile, circular polarization, and rotating-based phase shift, array antenna [7][8][9] has become an important research direction for HPM antennas.…”

Ku-band long linear helical subarray (LLHS) for a high-power cylindrical conformal array antenna has been developed. The LLHS consists of 80 helical antennas can be used to constitute conformal array of cylindrical surface. Through the research on the embedded probe structure, the adjustment of the coupling ability of different types of unit probes, the sealing method of the whole feeding, the problems of large feed reflection, and the uneven coupling amount of the unit probe in the rectangular waveguide system are solved, and the LLHS which can be used in the high-power conformal array is realized. The LLHS which is 52.35λ length can obtain 25.2 dB gain, 2.31 dB axis ratio, 90% aperture efficiency, −15.65 dB reflection at 12.5 GHz, and the reflection is lower than −14 dB during 12-13 dB. In addition, it could handle a pulse power of 166 MW under vacuum condition.

In this paper, a rectangular slotted waveguide array is proposed for high power microwave applications. The antenna has been designed in the context of implementing a nonlethal high power transmission device onboard a drone to stop and neutralize non-cooperative vehicles. The proposed antenna comprises 16 slotted waveguides and a beamforming network, which is folded to maximize the compactness of the antenna. It has been specifically designed to send maximum EM energy in the range 20°-30° off-axis direction to avoid undesired ground reflections during operations. It has the ability to withstand a peak power of 500 kW. A measured gain of 27.7 dBi has been obtained at 3.15 GHz. The antenna has been successfully used to stop a car engine from a distance of approximately 9 meters.
