摘要： When configuring a film antenna for receiving a circular polarized wave, at least one loop antenna is formed on a transparent plastic film and, at the same time, a non-powered element constituted by a wire-shaped conductor independent from the antenna conductor configuring the loop is arranged near this loop antenna. The non-powered element arranged on the side of the loop antenna is configured by a first part and a second part. The first part is made close to the loop antenna in a substantially parallel state. When a monopole antenna is used in place of the loop antenna, by combining this with a wire-shaped conductor orthogonal to this, it becomes possible to receive a circular polarized wave by a configuration providing a power transfer part between the two. It is also possible to configure a composite antenna by mounting another antenna on the transparent plastic film. This antenna can be used as an antenna of a navigation system.

摘要： To provide a broadcast receiving apparatus including an AM detector, an AM noise detector, an FM detector, an FM noise-level detector, and a threshold control unit. The AM detector performs AM detection on a broadcast signal in airwaves received by a receiving antenna that receives incoming airwaves to acquire an AM detection signal. The AM noise detector detects a signal portion, in which the AM detection signal exceeds an AM noise threshold, as an AM noise component. The FM detector performs FM detection on the broadcast signal to acquire an FM detection signal. The FM noise-level detector detects an FM noise level of the FM detection signal. When the FM noise-level detector detects the FM noise level of the FM detection signal, the threshold control unit changes setting of the AM noise threshold in the AM noise detector based on the FM noise level of the FM detection signal.
