II. INTEGRATED RADIO FRONT-END MODULEThe configuration of the proposed E-band integrated radiofront end is shown in Fig. 1. The module consists of a tightlyintegrated high-gain array antenna, a fifth-order diplexer, andthe Tx and Rx chipsets on a carrier board in four distinctlayers, where each layer has different functionality. The layersare vertically stacked up and integrated into a compact form.The proposed module has total dimensions of 110 mm ×90 mm × 8.5 mm.The bottom layer acts as a
