Abstract

1529776 Aerial couplings STANDARD TELEPHONES & CABLES Ltd 16 June 1977 25223/77 Heading H4A [Also in Division H1] A transmission line power divider for feeding signals to an antenna array comprises a microstrip hybrid ring structure having an input port 1, two output ports 2, 3 spaced equally from input port 1 by #/4 where A is the operating wavelength, two isolating ports 4,5 spaced equally from input port 1 by #/2 and separated by #/2, the two isolating ports 4, 5 being connected by an isolating resistor 8 equidistant between them.
