The usage of ultra-wideband (UWB) technology is growing in many communication systems such as radar systems, communication and measurement systems and imaging systems mainly because unlike the other wireless technologies UWB is not restricted to using a narrow waveband and it has high speed data rate. The large transmission bandwidth makes UWB-based electronic device resistive to interferences ...

─ A near-field focused folded transmitarray antenna is proposed at 2.45 GHz for medical applications. The proposed folded transmitarray construction introduces compact design, low profile, and reduced fabrication cost with focused power in both the near-field and far-field regions of the antenna. The transmitarray consists of a feeding horn antenna embedded centrally in the transmitarray struct...

A novel, potential and efficient microwave direct contact hyperthermia applicator referred to as water-loaded box-horn for therapeutic heating of bio-medium is designed and developed at 915 and 2450 MHz. Also, theoretical expressions for fields in bio-medium as produced by a direct contact box-horn applicator have been derived using plane wave spectral technique. The box-horn is a special type ...

A free-space microwave nondestructive testing and evaluation module is developed for the low-power, non-ionizing, contactless, real-time characterization of doped composite thin-film materials in an industrial context. The instrumentation proposed built up with a handled vector network analyzer interfaced corrugated horn antennas to measure near-field complex reflection S11 planar prepreg roll-...

We present the design, manufacturing and performance of horn-switch system developed for technological demonstrator QUBIC (the $Q$\&$U$ Bolometric Interferometer Cosmology). This is constituted 64 back-to-back dual-band (150\,GHz 220\,GHz) corrugated feed-horns interspersed with mechanical switches used to select desired baselines during instrument self-calibration. manufactured horns in alumin...
