TL;DR: In this paper, a three-component wide-band low-frequency magnetic antenna for diagnostics of magnetic fields in outboard space is considered and the basic technical, structural and exploitation characteristics of the MP-3M on-board active antenna are given.
Abstract: A three-component wide-band low-frequency magnetic antenna for diagnostics of magnetic fields in outboard space is considered. Methods of calculation of such antennas parameters and technical means for fulfilling the required characteristics are described. The basic technical, structural and exploitation characteristics of the MP-3M three-component on-board active antenna are given.

TL;DR: In this paper, a Gunn diode was integrated with an annular ring microstrip antenna to form an active antenna and the location for the diode placement was calculated based on a theoretical analysis for impedance matching.
Abstract: A Gunn diode has been integrated with an annular ring microstrip antenna to form an active antenna. The location for the diode placement was calculated based on a theoretical analysis for impedance matching. Over 70-mW output power was achieved at 6.8 GHz.

TL;DR: In this article, a generator circuit with symmetrical loading allowing to use this generator in the active antenna is proposed, and the original circuit solutions increasing both the amplitude and the pulse repetition rate are presented.
Abstract: Techniques for generation of UWB pulses of subnanosecond duration by semiconductor devices are considered in the given work. Characteristics of step recovery diode (SRD) generators and serial pulse diode generators are investigated. The original circuit solutions increasing both the amplitude and the pulse repetition rate are presented. A generator circuit with symmetrical loading allowing to use this generator in the active antenna is proposed.
