Continuous Transverse Stub Antenna in PCB Technology

We introduce here a new continuous transverse stub (CTS) antenna architecture compatible with standard, low-cost printed circuit board (PCB) technology for in-package systems. This enables a reduction of the cost, fabrication complexity and size of the antenna module. The antenna operates at E-band and its design, fabrication and experimental results are presented. To our knowledge, this is the first time that this technology is applied to CTS antennas. The measurement results are very promising: the radiation patterns are well-shaped, the gain variation over the 71-86GHz is lower than 3dB and the maximum measured gain is 17.2dBi.
