Adual-band, dual stacked microstrip patch antenna with Monopolar radiation pattern is proposed and analysed in this paper. An Annulus, TSAR and two sets of conductive vias are introduced into the structure to broaden the bandwidth and to drastically increase the antenna-gain. The realised impedance bandwidths are from 2.16 to 2.58 GHz in the low band and from 5.43 to 6.09 GHz in the high band, separately. The corresponding gains at low frequency band ranges from 7.1dBi to 7.8dBi and at high frequency band ranges from 8 to 9.7dBi. In addition, the proposed antenna has a low-profile structure, which can be easily placed on the top of a vehicle. In conjunction with these merits, the proposed design is very suitable for wireless local area network (2.4–2.48 GHz and 5.75–5.825 GHz), Satellite positioning system using S-band of NavIC (2483.50 – 2500.00MHz) and Vehicle to everything (5.85–5.925GHz) communications.
