Abstract
) of the π-slotted antenna are 35 mm and 31 mm respectively, which covers the operating frequency range 2.87-5.47 GHz. The MPA has a wide impedance bandwidth (2600 MHz), high radiation efficiency (90.88%), acceptable gain (2.647 dB) and low return loss (simulated: -36.81, measured: -25 dB). The VSWR over the entire operating frequency is regarded as 1 < voltage standing wave ratio (VSWR) < 2 and VSWR is 1.0293 at centre frequency 3.47 GHz. The current distribution on the surface as well as the input impedance of the π-shaped slotted MPA are also favorable. The MPA shows an omni-directional property over the entire operating frequency band. Since the time domain, frequency domain and fabricated results are buttressed by each other, the designed π-slotted MPA is one of the best candidates for high speed lower 5G/WiFi/WiMAX communication applications.
