Abstract
A novel three layers microstrip antenna element that has the advantages of wideband and high-gain is proposed. The eigenvalue equation and the frequency characteristic formulas of the input Voltage Stand Wave Ratio (VSWR) are obtained by using the spectral domain method and equivalent circuit method, respectively. With the aid of the numerical results, a C-band microstrip antenna element with bandwidth of 16% (VSWR<1.5) or 25% (VSWR<2) and gain of 10.2–11.3 dB is developed, which are much larger than the bandwidth of 5–6% and the gain of 6–7 dB of the common microstrip antenna element.
