This paper compares simulation results of a negative impedance converter (NIC) obtained from a circuit-only and circuit-electromagnetic (EM) co-simulation to demonstrate the impact of parasitic effects. The NIC is designed to produce a negative capacitance by cross-coupling two field-effect-transistors. In the circuit-EM co-simulation, the bulk of the transistors and other components are exactly modelled...
This paper presents a compact active circularly polarized antenna for Global Navigation Satellite System (GNSS) signal reception. The antenna is designed to operate at GPS LI (1,575 MHz) and GLONASS LI (1,602 MHz) bands, and its size is 64mm × 64mm × 7.42mm, suitable for mounting on a commercial drone. Within this limited size, hybrid-based orthogonal feed and two-staged low noise amplifier (LNA)...
