Design of the LTCC tooth-like-slot antenna

A new type LTCC antenna called tooth-like-slot antenna is proposed and experimentally studied in this paper. The proposed antenna is based on the LTCC technology and has both broad bandwidth and low cross polarization level. A prototype antenna is designed and measured in C band. From the measured data, the impedance bandwidth is about 20%, the cross-polarization level in E plane is about -35dB, and the one in H plane is nearly -22dB. Details of the proposed antenna and experimental results are presented and discussed.
