A novel quadband ultra miniaturized planar antenna with metallic vias and defected ground structure for portable devices.

Comparative Analysis of Five Planar Monopole Antennas for LTE/C-V2X/5G/WiMAX Applications

This paper compares the performance parameters of rectangular and circular micro-strip antenna for 2.4 GHz RFID wireless applications using IE3D simulation software. The main parameters of comparison are return loss, gain, and area. The main objective of the work is to obtain the reduction in the size of circular antenna compared to rectangular for same frequency of operation. Impedance matching between the feeder line and radiating patch is done using planar micro-strip transmission lines. Quarter wave feeding technique is used for both the antennas to provide best matching between antenna and the source. Simulation is done using IE3D simulation software and parameters like bandwidth, return loss, and gain are measured. Results are optimized using optimizing techniques and results are compared with practically measured results. Finally antennas are fabricated and tested using in-house facilities.
