Electrodynamic Сharacteristics of Short Microwave Band Antennas and Antenna Systems Research

The experimental and theoretical results research of broadband short antennas include antenna Vivaldi, made as symmetrical transmission slotline with exponential law changing aperture width are discuss. The analysis of directional diagram was getting for radiating antenna and system of two identical antennas, and influence it's geometrics on the directional diagram configuration and broadband response was researched.
