Harmonization of a Bandpass Shielding Enclosure and Its Internal Antenna

This paper investigates the way to harmonize a bandpass shielding enclosure (BPSE) and its internal antenna for achieving better performance. The harmonization greatly depends on the relative position of the antenna with respective to the adjacent periodic elements and the sideboards of the BPSE. For this harmonization, an internal high-permittivity dielectric resonator antenna is suggested due to its compact size and the minimum distance allowed between the antenna and the metallic sideboards of the BPSE. In addition, an appropriate zone for locating the antenna is suggested in terms of the relative position between the antenna and its adjacent BPSE elements. According to these suggestions, the antenna can be placed deep within a BPSE corner, a position which is often required in practice.
