Analysis of N-Slot Loaded Patch Antenna for Tripple Band Operation

Nand Kishore, Indrasen Singh, Vijay Shanker Tripathi




In this paper, the analysis of N-slot loaded microstrip antenna having single and double dielectric layer with coaxial feeding is presented using circuit model analysis. The antenna gives triple resonance and the separation between these resonances depends on the dimension of the slot. This antenna gives wide bandwidth for all three resonant frequencies for single dielectric and gives four bandwidths for double dielectric layer. It is observed that the resonance frequency decreases with increasing slot width but increases with increasing the slot length. The mathematical results are compared with the simulated results obtained from HFSSv12 and both results are close.
