Abstract
- In this study, a low temperature cofired ceramic (LTCC) based compact millimeter‐wave (MMW) 3‐D substrate integrated waveguide (SIW) filtering antenna was proposed. First, a band‐pass filter with two transmission zeros in the upper and lower sidebands was designed, with a fractional bandwidth of 2.03% at a center frequency of 98.1 GHz. The filtering antenna was developed and manufactured on this premise, by adopting an E‐shape patch antenna, achieving a superior frequency selection characteristic with a 1.63% impedance bandwidth and out‐of‐band gain dropped over 15 dB at 92.7 and 101.2 GHz, respectively. With a compact structure size of 2.4 × 1.6 × 0.5 mm3 (0.78 λ0 × 0.05 λ0 × 0.016 λ0), high gain and high selectivity were realized in the MMW band. [ABSTRACT FROM AUTHOR]
