A Novel Negative Meander Line Design of Microstrip Antenna for 28 GHz mmWave Wireless Communications

The increasing applications for nomadic computing have experienced enormous development over the preceding decade. This has eventually caused the lack of bandwidth. Therefore, to accomplish the need of consumers, compact antennas shall be designed for mmWave wireless communications. Consequently, this paper presents a novel negative meander line based microstrip antenna system being composed of inductors (L) and capacitors (C). A detailed impedance analysis of the configuration is reported. The effects of changing the radiating element’s width and length on the resonant frequency have been studied. The finalized arrangement involved 243 sq. mm area and functioned at 28 GHz with a bandwidth of 2.16 GHz. At resonant frequency, the system exhibited gain and efficiency values of 8.40 dBi and 83.51%, respectively. Furthermore, the proposed design demonstrated better bandwidth and gain capabilities in comparison with the conventional microstrip patch antenna and meander line antenna.
