Abstract—The input impedance and the antenna gain of the spherical eTg8I/)%B  
helical antenna are obtained theoretically and experimentally. Results indicate MWdev.m:Z  
the better performance of the 3-turn antenna over the 7-turn one in (V&5EO8)  
terms of the impedance bandwidth and the stability of the antenna gain. <P

The theoretical current distribution is also obtained and its salient characteristics 9mE6Cp.Wv  
are discussed. C,;T/9
