Performance Comparison of Microstrip Patch Antenna Using h-BN Nanoceramic Substrate and FR4 Substrate

Abstract

The recent communication receiver requires compact size, low cost, less weight and high-performance antenna for broadband applications. This paper compares the performance of the microstrip patch antenna designed using h-BN nano ceramic substrate with antenna designed using FR4 substrate. In this proposed new substrate is developed using powder metallurgy principle. Simulated and experimental results shows that proposed substrate for patch antenna in S-band applications achieve good resonance at two different frequencies 2.2 and 2.6\xa0GHz with reflection coefficient of −35 and −40\xa0dB respectively. Same antenna structure using FR4 structure is achieving good resonance at multiple frequency and broadband characteristics in C-band and X-band of the radio spectrum.
