Disclosed is a flat-type antenna apparatus which has a radiating conductor and a reference conductor disposed opposite to each other and performs feeding between the radiating conductor and the reference conductor at a position offset from the center of the radiating conductor center. The antenna includes: an insulative material layer which has relative magnetic permeability greater than 1 and is placed in a gap between the radiating conductor and the reference conductor; and a short-circuiting conductor which is disposed at a position to suppress unintended excitation and enables electric conduction between the radiating conductor and the reference conductor.

A novel and useful apparatus for and method of nonlinear adaptive phase domain equalization for multilevel phase coded demodulators. The invention improves the immunity of phase-modulated signals (PSK) to intersymbol interference (ISI) such as caused by transmitter or receiver impairments, frequency selective channel response filtering, timing offset or carrier frequency offset. The invention uses phase domain signals (r, □ rather than the classical Cartesian quadrature components (I, Q) and employs a nonlinear adaptive equalizer on the phase domain signal. This results in significantly improved ISI performance which simplifies the design of a digital receiver.
