Small antenna using transmission line uniform for X-band navigation radar

In this research, a co-planar antenna with a small dimension is presented for vessel navigation radar. The radar, will be produced in a compact size so that it can be used at any type of vessels. The small antenna was fabricated on Duroid series 6006 with a permittivity value εr of 6.15. This enables a production of smaller antenna dimension, in comparison to the dimension of our antenna from the previous researches. The frequency center of the antenna is 9.4 GHz. The antenna will be implemented in a uniform configuration consisting of 16 modules for transmit and receive parts to achieve an equal phase. The simulated and measured results show similarity in performance. The overall antenna dimension is 40 cm × 0.27 cm, while it was 1600 cm × 10 cm in the previous design.
