Abstract :
An E-type microstrip slot antenna with parasitic patches (EMSAPP) in Ka-band is proposed in this paper. The developed prototype of this antenna employs a multilayer Low-Temperature Co-fired Ceramic (LTCC) substrate. The antenna installs five patches on two LTCC layers, the 2×2 parasitic patches on the upper layer and the radiation chip on the lower one. In this paper, the E-type patch is used instead of the radiation chip to increase the antenna´s bandwidth. The proposed antenna by simulation can achieves 8.45 dB absolute gain at 35 GHz and while the fractional bandwidth of -10 dB return loss is 6.5% (from 34 GHz to 36.3 GHz). By compared with conditional works, the use of the E-type patch can indeed increase the antenna´s bandwidth.
