Abstract :
A new wire antenna is proposed namely the S-shaped dipole antenna. The radiation characteristics are obtained using the method of moments (MoM) with one-volt delta gap source and suitable dimensions for this antenna. From the obtained characteristics the antenna is considered of wide bandwidth. The given discussions proved the feasibility of using such antenna in a wide range of applications in the VHF and UHF frequency ranges both in free space and with a perfectly conducting ground plane. The proposed S-shaped antenna radiates left elliptically polarized (LEP) waves. Right elliptically polarized (REP) waves are obtained using the inverted S-shaped dipole antenna. Also circular polarization of both senses is obtained using the turnstile arrangement.
