A Cross-Feed Wideband Patch Antenna and Its Hi-Gain Application
A novel cross-feed wideband patch antenna and its hi-gain application is investigated. The antenna elements are cross-fed by parallel broad brimmed coupled lines to actualize impedance match and enhance gain. Theoretical analysis and simulation results show that the antenna fabricated on a epsivr =2.6 permittivity substrate of h =1 mm thickness can achieve 53% impedance bandwidth (VSWR<2.0) and maximal gain reaches 4.8 dBi, with perfect far-field radiant characteristics and stable phase center. By mounting reflectors and directors around the antenna elements, adjusting parameters, 7-12 dB gain in 51% impedance bandwidth can be achieved. The antenna is easy to design and fabricate. The design parameters can be adjusted easily. The antenna takes on high value in application.
