“…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 order to solve the issue, we report a metal-only easily fabricable three-dimensional antenna. The metallic antenna has higher power handling capacity than microstrip antenna and dielectric resonator antenna [15] because of dielectric breakdown. Therefore, this antenna can be used for high power transfer applications such as base station antennas.…”

Desire for a broadband, high gain, unidirectional and low cost antenna in the field of communications is everlasting. In this paper, a novel broadband high gain antenna is presented using a suspended cylinder and a ground connected cylinder geometry. The bandwidth of the proposed antenna is enhanced by shorting these two cylinders with a pin in the direction orthogonal to the plane of coaxial probe. This low profile antenna structure is simple and easy to fabricate. The cylinders, shorting pin and ground plane are fabricated by a copper sheet of thickness 0.4 mm. Shorting pin and SMA connector provide mechanical support to the suspended cylinder. Simulations are done to analyze the radiation performance of the antenna. Prototype of the antenna is fabricated, and the measured results show good agreement with the simulated ones to confirm the enhanced bandwidth offered by the proposed antenna. We achieve impedance bandwidth of 63% (2.6-5 GHz) with the peak broadside gain of 9.87 dB. The bandwidth of the proposed antenna can be tuned by changing the radius of the shorting pin. The designed antenna possesses broadband high gain with stable broadside unidirectional radiation pattern which is suitable for Base station antenna such as WiMax (Worldwide Interoperability for Microwave Access) and LTE (Long Term Evolution). The metallic antenna has high power handling capacity as compared to microstrip and dielectric antennas. Therefore, this antenna can also be used for high power transfer application.
