Abstract
- This paper presents a circularly polarized (CP) slot antenna array using substrate integrated waveguide (SIW)–feeding network at Q-band. To achieve CP radiation and high-gain performance simultaneously, a metallic radiating slanted cross slot is stacked atop an SIW coupling slot in the CP antenna element design. The fabricated CP antenna element features 14.6% (42.6–49.3 GHz) measured impedance bandwidth for |S<subscript>11</subscript>| ≤ −10 dB, 9.1% (42–46 GHz) measured 3-dB axial ratio (AR) bandwidth for AR ≤ 3, and 8.3 dBic measured peak gain, respectively. Then, a 1 × 8 antenna array is designed, fabricated, and measured. The measured results demonstrated that the impedance bandwidth and 3-dB AR bandwidth of the proposed 1 × 8 array are 14.8% (41.9–48.6 GHz) and 11% (43–48 GHz), respectively. The measured peak gain of the 1 × 8 array is 14.7 dBic at 44 GHz. [ABSTRACT FROM AUTHOR]
