| Popis: | In this letter, a design procedure of the K-band slot antenna array in corner reflector is described. The array consists of eight slots as radiating elements with parallel-series feeding by coplanar waveguide (CPW) transmission line. The uniform rectangular slots stand asymmetrically in relation to the CPW feeding line. The apex of the corner reflector is at the distance around 1.4λ 0 in respect to the center frequency f c =25.875 GHz from the antenna array. The corner reflector increases antenna gain and improves control of radiation pattern that is desirable for many modern wireless applications. The proposed antenna array features gain of 21.6 dBi and side lobe suppression of 14.2 dB at the center frequency, while it keeps satisfied radiation properties in a wide frequency range between 24.8 GHz and 27.1 GHz. |
