Design and Analysis of Printed Planar Compact Broadband Dual Frequency Antenna in FR4 Substrate for Signal Processing Applications

This research study proposes a printed compact dual frequency broadband antenna, which can radiate at two resonant frequencies such as 2.1GHz and 5.80 GHz. The proposed antenna is designed in Ansoft Magus CAD EM simulation tool. The material substrate used here is FR4 substrate with εr=2.2, tanδ =0.001, and h =0.254 mm. The operating frequency is designed for ISM band 5G application for performing multi-band switching in mobile phones. The antenna dimension considered here is 23mmX 68mmX 254μm, a compact structure which can be easily embedded in any random area. The simulated output involves simulated parameter values, which are acceptable for fabrication & the testing total gain is 2.17 dBi with VSWR = 2 and Zin= 45Ω.
