In this paper, a novel over-moded bent circular waveguide mode converter is proposed to extract a hybrid HE 11 mode from a relativistic backward wave oscillator (BWO) to feed an antenna. It uses a smooth wall dual bent circular waveguide to convert a

We present results of simulation, fabrication, and testing of an S-band narrow-wall longitudinal slot antenna designed for high-power-microwave (HPM) systems. A key aspect of the proposed antenna structure is the use of longitudinal slots in the narr

A simple method for the design of rectangular slotted waveguide antennas (SWAs) with specified sidelobe levels is briefly described, and is used to design an example SWA with 7 broadwall elliptical slots and sidelobes lower than −20 dB. A special c

This work seeks novel designs of S-band high power microwave antennas based on rectangular waveguide narrow-wall longitudinal-aperture array structure. A narrow-wall slot-array is proposed to achieve higher gain. It consists of two identical narrow-w

Horn antennas are widely used in high power microwave systems, mainly due to their high power handling properties. Different variations of the traditional horn antenna geometry have been introduced in the past years to improve the radiation character

In this paper, a split-ring-resonator-loaded sub-wavelength waveguide with H-plane-bend (HPB) radiator structure is proposed. Improved matching is applied to minimize the reflected power at the input. This proposed waveguide is used as part of a high

In this work, an S-band slotted waveguide antenna (SWA) with optimized corrugations is presented. It is based on 10 identical longitudinal elliptical slots cut in one of the broadwalls of a WR-284 waveguide (a = 2.84″, b = 1.37″). The waveguide i
