Growth of the Antennas and Propagation Field between World War I and World War II Part I - Antennas

The advances in antenna theory concepts and designs between World War I and World War II are summarized. Rapid growth of world-wide and regional broadcasting and point-to-point radio communication stimulated the design of high-power low-frequency transmitting antennas of reasonable efficiency, directive-wave antennas for signal-to-noise improvement in low-frequency reception, rhombic and V-shape wave antennas and arrays of various types for directive short-wave transmission and reception.
