摘要

提出了一种实现小型宽带端射毫米波天线的设计方法。为了实现紧凑的设计，采用了介质负载腔背槽天线。此外，还采用介电匹配层来实现宽带操作。该天线在27.4 GHz ~ 40.8 GHz范围内的电压驻波比(VSWR)为2.1，发射端增益在4 ~ 5.5 dBi范围内。设计尺寸为2.2 × 2 × 5 mm3，即0.2 × 0.18 × 0.45 λ3max，其中λmax为最低工作频率下的自由空间波长。此外，天线由微带馈线馈电，当考虑到连接到RFIC时，这是一个优势

Dual-Function Dielectric Layer Enabling Compact Wideband End-Fire Millimeter-Wave Antenna

A design methodology to accomplish compact and wideband end-fire millimeter-wave antenna is presented. A dielectric-loaded cavity-backed slot antenna is utilized to achieve the compact design. In addition, a dielectric matching layer is employed to enable the wideband operation. The antenna achieves a voltage standing wave ratio (VSWR) of 2.1 from 27.4 GHz to 40.8 GHz with an antenna realized gain in the end-fire direction ranging from 4 dBi to 5.5 dBi. A compact design of 2.2 × 2 × 5 mm3, which is 0.2 × 0.18 × 0.45 λ3max where λmax is the free space wavelength at the lowest operating frequency. Moreover, the antenna is fed by the microstrip line feed, which is an advantage when the connection to RFIC is considered
