The article proposes a microstrip patch antenna for vehicular communication applications under 5G communication frequency band. The dimensions of the antenna play an important role in the field of vehicular communication applications. The antenna dimensions are optimized by introducing back propagation algorithm. Overall dimension of the antenna is reduced by 16% as compare to the traditional formulations. Further fractal geometry is implemented on the patch and recessed ground as defected ground structure. FR4 epoxy is used to construct the substrate of the proposed antenna with the dimensions of 50 mm × 60 mm × 1.6 mm and the patch is designed as rectangular patch with H‐cut and I‐cut. The proposed antenna is simulated using Ansys high frequency structure simulator v15 and the frequency of operation is 27 to 33 GHz. The antenna parameters such as reflection coefficient, voltage standing wave ratio, gain, radiation, and current distribution are investigated. The antenna is designed in compact in shape such that it is suitable for vehicular communication applications.

In this paper “Micro Strip Patch Antenna (F-MSPA)” based on fractal is proposed to perform operations over multiband for a specific time bound. This is designed specifically for “Wireless Power Transmission (WPT)” System which is light weight or it is low profile and light weight when implemented. The main aim of proposed methodology or design of antenna is attained by implementing the basic patch called as the rectangular patch, whose scope is till the third level. Based on this the shape of rectangular cuttings are obtained. The antenna is excited by the obtained or generated micro strip feed as the operations of antenna are performed over various frequency ranges between 1GHz to maximum of 5 GHz. The proposed method comprises of fractal antenna resonant with quad frequencies that ranges: 1.86GHz / 2.29GHz / 3.02GHz / 4.50GHz along with their generated loss values are 13.59dB / -23.66dB / -15.94dB / -15.69dB. Proposed antenna simulation is performed using Ansoft HFSSv13 a high frequency structure simulator.

Antenna design plays a prominent role when we consider the far-field patterns when compared with near field patterns. By using a PIN diode (which has a wide intrinsic region when compared with normal diode) as a switch and a capacitor as a filter we are proposing an antenna design that able to radiate far field regions. The reason behind choosing capacitor as a filter means that we are designing antenna to transfer high frequency signals. For antenna deign simulations we have different software’s (like FEKO, ZELAND IE 3D etc.,) but the preferred software for this antenna design is Computer Simulation Technology Microwave Studio (CST MWS) as we are operating in a frequency band of 2 to 2.54GHz and the diameter of the antenna 20X20cm. Based on the diameter chosen the antenna is able to switch direction of signalling by using a switch with four different angles. The material used for antenna design FR-4 which is a Composite material composed of fibre glass cloth with an epoxy resin blinder i.e. frame resistance and SMB connectors with 75Ω impedance.
