Broadband printed monopole antenna

2006 IEEE Antennas and Propagation Society International Symposium, 2006
A novel broadband printed monopole fed by microstrip line is proposed. The antenna operates over wide frequency band (from 2.4 to 6.8 GHz) with impedance close to 50 /spl Omega/ and ...

Broadband omnidirectional helmet antennas

2006 IEEE Antennas and Propagation Society International Symposium, 2006
In this paper a new class of helmet antennas with omnidirectional pattern has been developed. Its radiation performance is considerably superior to that of conventional resonant whip antennas for terrestrial field applications over a much wider bandwidth and with more stable connectivity regardless of the wearer's body movement and orientation.

Broadband slotted cone antenna

IEEE Transactions on Antennas and Propagation, 1966
A new UHF-VHF antenna has been designed that is electrically small and exhibits multioctave bandwidth properties. This electrical hybrid design features ruggedness, light weight, compactness, and low profile. Experimental results indicate that the Slotted Cone Antenna radiates primarily vertical polarization and, like the monopole, exhibits an ...

Broadband nested antenna

This thesis investigates a novel dual frequency range low profile antenna system containing two nested spiral antennas operating over 2 – 18 GHz and 30 – 40 GHz respectively. The exploration and development of a broadband microstrip spiral without cavity backing has been implemented in the range of 2 - 18 GHz.
