A novel leaky-wave antenna implemented in the low temperature co-fired ceramic (LTCC) is presented. Introducing cavities in the structure and removing the conductor planes between tape layers improve radiation efficiency and gain. Moreover, tapering the aperture of the antenna leads to about 10dB reduction of side-lobe level. The antenna has an operating band from 28.3 to 29.1 GHz that is among the proposed 5G frequency bands. The realized peak gain and radiation efficiency of the proposed antenna over the operating band are about 8.5 dB and 80%, respectively. The length, width, and height of the antenna are 40 mm, 16 mm, and 0.5 mm, respectively. The compactness of the antenna and the characteristics of LTCC structure makes it a suitable nominee for modern circuit integration.
