Abstract :
A novel method of designing broadband microstrip antenna is proposed in this paper. By embedding a pair of Cross-shaped slots placed close to the non-radiating edges of a microstrip patch and adding an air layer between the substrate and the ground, the broadband character can be achieved. What´s more, the formulas for calculating the two resonant frequencies have been experimentally deduced. Employing the method and the formulas, a antenna with a pair of double cross-shaped is designed. The measured bandwidth of 15.2% is achieved with small sizes, and the good radiation characteristic for operating frequencies within the impedance bandwidth is also observed.
