A Compact Broadband Slot Antenna for Indoor Distributed Antenna Systems

Authors(3) :-Sudarshan Bandi, Kancherla Swetha, Swamy Polgoni

A compact omnidirectional vertical-polarized broadband slot antenna for indoor distributed antenna systems is presented. The proposed antenna consists of a deformed printed monopole on one side of the substrate and a polygon slot in the circular ground plane on the other side. Due to the utilization of the wideband slot structure, the antenna achieves small electrical dimension of 0.327λ × 0.327λ × 0.0046λ at the lowest operating frequency, and an impedance bandwidth of about 129% (0.66–3.07 GHz) for VSWR ≤ 1.5 is achieved, covering all frequency bands for 2G, 3G, 4G and some Wi-Fi communications. The proposed antenna has stable radiation patterns over the operating bands. The measured gains of the antenna range from 1.5 dBi (lower band) to 5.5 dBi (higher band). Compact planar structure makes the proposed antenna a perfect candidate for ceiling or surface mounted indoor distributed antenna applications.
