摘要

At the firstly single element of the singly fed pentagonal patch antenna using air gap is proposed. The results show that the bandwidth of impedance axial ratio and gain at the resonant frequency 2.4925 GHz are 15.67 %, 4.11 % and 52.16 %, respectively. Moreover the value of S-parameter axial ratio and gain at 2.4925 GHz are −15.03 dB, 0.06 dB and 8.74 dBic, respectively. Furthermore in this research it is also investigated circularly polarized array pentagonal microstrip antenna for mobile satellite communications especially to enhance the bandwidth axial ratio that are examined both of simulation and measurement. The results of array pentagonal patch antenna is similar with its single especially the value of S-parameter axial ratio and gain as the mentioned above. The other results related the simulation show that the cutting of beam angle between of them is the same. In case of measurement results owing to loss during measuring the gain decreasing and affect the cutting of beam angle between gain and axial ratio that is not satisfied yet.
