A Broadband Dipole Antenna for Multiservice Indoor Distributed A...

Multiservice indoor distributed antenna system (MS-IDAS) plays an important role in wireless communications. This letter investigates a broadband antenna for MS-IDAS, which is composed of a loop-loaded dipole, a microstrip feeding line, and a flat reflector. Through the loop-loaded structure, the low frequency band is greatly extended. A prototype with dimensions of 180 mm x 150 mm x 50 mm is presented to cover the frequency band of 880-2700 MHz. Indoor coverage experiments prove that high quali
