摘要

设计了一种带有收发开关和低噪声放大器的有源集成天线.收发开关基于PIN二极管设计，采用非对称拓扑结构和阻抗变换网络实现了低插损和高收发隔离的特性.协同设计天线、收发开关及低噪声放大器（LNA），省去了天线与收发开关之间的匹配网络，并简化了收发开关与低噪声放大器之间匹配网络的设计.实际加工的有源集成天线测试与仿真结果基本一致，在7.8～8.1GHz频率实现了良好的匹配和辐射性能，且结构紧凑.

Abstract

Design of an active integrated antenna with transmit/receive switch and low-noise amplifier was proposed. The transmit/receive switch is based on PIN diodes, and uses asymmetric topologies and impedance transformation networks to achieve low insertion loss and high transceiver isolation. By collaborative design of the antenna, transmit/receive switch and low-noise amplifier (LNA), the matching network between the antenna and transmit/receive switch is eliminated, and the design of matching network between transmit/receive switch and LNA is simplified. The measured and simulated results are basically consistent. In the range of 7.8—8.1GHz, the active integrated antenna achieves good performance and is with a compact size.

Key words： active integrated antenna; PIN switch; low-noise amplifier (LNA); co-design; direct matching
