摘要: A small closed loop antenna is formed by a flat metal member into U-shape which also serves as the front, back and top surfaces, or parts thereof, of housing for portable communications receiver. Connected to open (bottom) end arms an isolation network providing optimum ground reactance applies capacitive across so that conductive forms detects H-field electromagnetic wave be received. The tunable adjust reception at particular frequencies.
