Investigation of LTCC-based patch antenna for Wireless Applications

Abstract

This work reports the design, development and demonstration of a low-loss rectangular micro-strip patch antenna for WLAN applications using a low-temperature co-fired ceramic (LTCC) substrate. The proposed antenna was simulated in CST Microwave Studio. The patch is printed on a Dupont-LTCC substrate with a dielectric constant of 7.8 and has a 1 mm thickness. The developed antenna with a centre frequency of 5.95 GHz has been demonstrated for video transmission. The S11 obtained experimentally is -29.34 dB with a VSWR of 1.17, which is close to the simulated results.
