“…Monopulse technology has attracted extensive concern in modern radar and communication applications. A monopulse system can offer blind-free ranging and high resolution by combining frequency modulated continuous wave (FMCW) technology with limited bandwidth [1], [2]. Therefore, a narrow band antenna can be compatible with the FMCW monopulse system.…”

A high gain low sidelobe monopulse microstrip array antenna for Ku-band frequency modulated continuous wave (FMCW) radar application is proposed. The design consists of microstrip array radiation front-end and waveguide coupling slot array feeding network back-end. The microstrip array comprises 16×32 series-fed patches etched on the top side and slotted ground on the bottom side. A series of shunt slots in the broad-wall are loaded on a WR51 standard magic Tee waveguide to form a compact low loss monopulse comparator and hybrid feeding network. The radiation front and feeding network is individually fabricated with standard printed circuit board (PCB) and machining process and then can be integrated by advanced assembling process. Precise alignment of waveguide slots and ground slots is obtained during these procedures to achieve accurate excitation. Measured results are in accordance with simulation results and show about 32.5 dBi max gain and-25 dB sidelobe level (SLL) of sum pattern in E plane and-27 dB null-depth of difference pattern at 17 GHz center frequency.

decreases with increasing R v , however, the stopband attenuation also decreases with increasing R v . This causes a trade-off between these two parameters. In this LTCC BPF design, we wish to achieve the passband insertion loss was lower than 2.0 dB, and the passband return loss was higher than 12 dB. The required stopband attenuation levels are set to values greater than 20 dB above 4.0 GHz to suppress the second harmonic band of the operating frequency. The final prototype element solutions that are chosen to satisfy all the specifications are: C c 5 1.68 pF, L p1 5 0.529 nH, C p1 5 6.86 pF, R 5 255 X. By referring to Figure 4, the U-shaped inductor requires a length of 1.98 mm for having such a specific L p1 value of 0.529 nH.
