N2 - A compact and high-gain SIW-fed circularly polarized (CP) slot-antenna
array with a stacked feed structure is presented for the application of
Ku-band high-data-rate satellite communications. First, a novel
probe-fed SIW cavity with four slots etched on the top surface is
proposed as a high-gain radiating element for the array. The four slots
in the cavity act as a 2 x 2 array, and its directivity is 2.15 and 1.43
dB greater than that of the cavity-backed antenna of the same size
using ring slot and split ring slot, respectively. Second, a compact 1-4
SIW power divider is designed for exciting a subarray. Third, the 2 x 2
subarray is further expanded to an 8 x 16 array by adopting an
additional layer of 1-32 SIW feeding network to meet the gain
requirement of the Ku-band mobile satellite TV reception. Finally,
experiments are carried out to verify the designed prototypes. Measured
results show that proposed 128-element array has a relative impedance
bandwidth of 4.8% (11.84 to 12.42 GHz), AR bandwidth of 130 MHz (12.01
to 12.14 GHz), and a peak gain of 26.8 dBic at 12.06 GHz. Owing to the
simple feeding networks and the compact radiating element, the antenna
has a compact size of 6.04λ0 x 11.96λ0 x 0.1λ0.
Experimental results show that the proposed CP antenna array is
suitable for applications of Ku-band mobile satellite TV reception.
