ABSTRACT
A novel design of a P-shape microstrip antenna is proposed. The stub in the P-shape patch modifies the frequency and resonant mode distributions at second-order TM20 mode which along with TM10 and TM01 modes yields dual-polarised triple-frequency response, showing 1−1.5% of impedance bandwidth (BW) at each frequency. To enhance the gain, air-suspended designs for the P-shape patch are proposed. It yields the broadside gain of 1.5−5 dBi across three frequencies. Enhancement in BW of the P-shape patch is obtained by using its gap-coupled variations leading to 69- or 96-shape configurations. On a thinner substrate, these gap-coupled antennas give BW of 3−5% across three frequencies.
