This letter proposes a new bandpass shielding enclosure (BPSE) for modern handheld communication devices. This enclosure is characterized by high transmittance at the specified wireless signal band and high shielding effectiveness (SE) outside this band. In addition, it has little influence on the impedance-matching bandwidth and antenna patterns of an internal antenna embedded inside the device. A prototype was created, simulated and measured. The simulated and measured results demonstrate the promising performance of this newly proposed shielding enclosure.
