We show that metallic wires embedded in narrow waveguide bends and channels demonstrate resonance behavior at specific frequencies. The electromagnetic energy at these resonances tunnels through the narrow waveguide channels with almost no propagatio

This article reports on a novel direct frequency multiplication and phase modulation (PM) scheme for mechanical antennas operating at the very-low-frequency band (3–30 kHz) and lower. This antenna is intended as a transmitter for underwater and und

A 75-83GHz waveguide band-pass filter is designed and fabricated for harmonic rejection of a multiplier chain used in a polarimetric automotive radar. The radar uses a multiplier/amplifier chain to achieve the desired signal at E-band from a source a

This paper presents a new single-antenna polarimetric active radar calibrator (PARC) intended for the polarimetric and absolute radiometric calibration of the NASA’s soil moisture active passive (SMAP) radar. The PARC receives and retransmits the S

A directional repeater system with simple architecture composed of wideband receive and transmit antennas, a high gain low-power amplifier, and a bandpass filter is proposed for the 2450-MHz ISM band. The repeater system does not require down-convers

In this paper, a simple but very accurate circuit model for two-port (split) loop antennas typically used for direction finding in the HF-band is presented. The circuit model consists of lumped elements and can be used to accurately estimate the inpu
