Radio Detection and Ranging are used for object detection, distance and altitude measurement, and mapping. RADAR can be used in bad weather conditions and can see objects under the sea and in the air at great distances. Ship radar is one of the technologies in the shipping sector, especially in the marine sector navigation system. For that, we need an antenna that has a compact design, small size, wide bandwidth, and can be used to meet the operating frequency of the radar system. Microstrip antenna is a type of antenna that is currently widely used in several devices as an alternative because the manufacturing process is simple and inexpensive. Ordinary microstrip antennas work on one frequency (single band). By using DMS (Defected Microstrip Structures) the antenna can work in multiband. Therefore, the author tries to design a Multiband antenna using DMS for marine radar which is known to operate at the S-band (3 GHz) frequency, following the specifications of the radar antenna. The substrate used is FR-4. This research method uses CST 2019 simulation as simulation software.The simulation results at a frequency of 3.0046 GHz show a VSWR of 1.0764 and a return loss of −27.9 dB. From the simulation results, we can analyze that to get the characteristics of the antenna according to the desired specifications, namely working at a frequency of 3 GHz, VSWR 2, and Return Loss −10.

“…Monopulse array systems are one of the most favorite structures used in SSR systems [4]. The monopulse anten-nas are available in planar array type [5,6,7], modal Horn Type [8], [9], reflector type [10][11][12] or even waveguide arrays [13]. Use of monopulse methods [10], [4] for ranging and angle of the arrival estimations which necessitate generation of two SUM and Difference (DIFF), and for more reliability in SSR, use of Control (CTRL) beams out of its antenna system.…”

In this paper, the design and fabrication of a large array antenna with three required, Sum, Difference and Control beams for a monopulse Secondary Surveillance Radar (SSR) is presented. A special array element, which is a high gain dual dipole structure, is designed and tested. This element has 9.6 dB gain in 1060 MHz and does not need any balun. The main challenge of extracting three beams out of one beam feeding networks (BFN) has been resolved efficiently by maximum integration of all three in one network, reducing the number of required modules to one half. The complete 33-element array, working in 1030 MHz and 1090 MHz is designed based on the Taylor array factor. The complex feed network of this 6-meter long array has successfully been synthesized as modular as possible. Sum pattern was designed for 2.7 o azimuth beam width and -20 dB side lobe level and Diff pattern with a deep null in the boresight of the Sum pattern. The Ctrl beam was also designed in order to cover the Sum beam except in the direction of the main lobe.
