Abstract :
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 ×150 mm ×50 mm is presented to cover the frequency band of 880-2700 MHz. Indoor coverage experiments prove that high quality signals are provided by the antenna within the designed bandwidth, which is a decent candidate for MS-IDAS.
