Multilayer Microstrip Antenna for broadband Applications

Rupesh Budharam Raut, V.D.Nagrale

Abstract: A novel broadband multilayer-layer coaxial coupled patch antenna is proposed. A simple patch geometry that is based on a rectangular patch which is place above the ground at a height (h1 +h2) fed by oaxialc coupled is introduced in this paper. A new resonant mode is excited using this novel patch structure. The results shows that the bandwidth is 450 to 750 GHz (S11<10dB), larger than 40 %. The gain is achieved to 4.65dB. The radiation patterns are similar and the gain can meet the demand for the communication applications over the operating frequency band. Simulation are done by using high Frequency Structure simulation (HFSS).
