Abstract:

Because of the expansion of channel capacity,broader-band is considered as the basic requirement of communication antennas.A new type of missile-borne communication antenna is proposed.The requirement for small size and wide frequency bandwidth are met by loading slots and CPW-fed structure.The characteristics of E-plane omni-directional and broadband are shown by the simulated data.The structure of the antenna is characterized by compact size,simple feeding,broad bandwidth,simple structure and easy fabrication.

Key words: microstrip slot antenna;CPW-fed;missile-borne antenna
