Design of Compact Microstrip Antenna Array with Decoupling Network
By
Progress In Electromagnetics Research Letters, Vol. 60, 59-65, 2016
Abstract
An innovative decoupling microstrip antenna array is designed. In the design approach, a decoupling and folding microstrip circuit is proposed instead of lumped element circuit, so that the circuit structure is simplified, and the antenna array is fabricated easily in print. Inverted L shape is used as its radiator in order that the size of the antenna array is miniaturized. Stepped impedance transformer is added for the sake of weakening ports reflection. The simulation and measurement results show that the proposed antenna array works at 2.45 GHz, and its reflection coefficient and isolation are both below -20 dB in the working band (2.4 GHz-2.48 GHz). The proposed antenna array has patterns close to omnidirectional.
