Abstract
Paper presents the calculated characteristics of the dual frequency microstrip antenna working in C- and L-bands. Results were obtained by finite-difference time domain method. Dual frequency antenna consists of perforated patch for the L-band and 2×2 patch elements subarray for C-band. Paper focus on radiation and matching characteristics and also investigates mutual coupling effects of integrated antenna in both frequency bands for different sizes of perforated low frequency radiating patch. It was shown that mutual coupling effects can considerably deteriorate input impedance matching characteristics and moreover leads to the radiation pattern distortion and side lobe level increasing for higher frequency band. Developed dual frequency antenna can be the key element for the large dual frequency planar antenna array.
