Abstract

In this paper, we have proposed a novel structure of Ka-band based phased array antenna with calibration function. In the design of Ka-band antenna, the active phased array system is adopted and the antenna would work in the dual polarization separation mode. We have given out the schematic diagram for the proposed Ka-band antenna, where the Ka-band antenna is in the form of waveguide slot array antenna, with 96 units in azimuth and 1 unit in distance. Each group of units is driven by a single-channel Transmitter/Receiver (T/R) component, and the whole array contains 192 T/R components in total. The size of the T/R component is 55 mm (length) × 50 mm (width) × 5.8 mm (height), 3 Sub-micro Sub-Miniature Push-on (SSMP) blind sockets and a 21-core low-frequency socket are designed on the two sides of the T/R component. In order to meet the technical specifications of phased array antenna, the Ka-band transceiver component is designed based on Low Temperatrue Co-fired Ceramic (LTCC) technology to achieve miniaturization and lightweight. In our approach, the feed network includes two parts: transceiver network and calibration network. The transceiver network consists of 24 1:8 time-delay power dividers, 12 two-way power dividers and 2 six-way time-delay power dividers. The power supply required by the Ka-band antenna unit is provided to each active component by the power module after Ka band wavelet control distribution. Simulation and measurement results are given in the form of standing wave and scanning capability.
