IV. EXPERIMENTAL RESULTS AND DISCUSSION
A split-ring rectangular slot antenna structure was designed
and implemented. The antenna is connected with a network
analyzer to measure return loss and input impedance. The
measurement results are compared with the simulation results.
The discussions are given with the results.
Fig. 5 shows the prototype of a split-ring rectangular slot
antenna structure. The dimension of the antenna prototype
closes to the dimension from designing. The split-ring
rectangular slot antenna defined by above structure parameters
are fabricated and measured by Agilent HP8720C network
analyzer, is connected with the antenna prototype to measure
the return loss by using coaxial cable 50 n type RG-142
connecting together.
