Helical Antennas

A novel broad band and wide beam microstrip helical antenna is proposed based on the modification of traditional helical antennas. Through selecting the appropriate operating mode between the axial mode and the normal mode, this new antenna can broad both the beamwidth and the bandwidth. To improve the gain of the antenna, An antenna array with 1*16 elements is designed and fabricated. Meanwhile, cavity-loaded feeding network is utilized for probe station measurement. The simulated impedance and radiation pattern are studied. The proposed antenna shows a wide impedance bandwidth from 7.6GHz to 9.6GHz for |S11|<-10dB, with wide 3dB beamwidth of E-plane about 1200, respectively.
