Phased arrays for use in future multifunction systems require wideband elements capable of wide angle scanning. Here we describe the design of a Balance Antipodal Vivaldi Antenna for use in large phased array antenna apertures. The BAVA element height and the array lattice spacing are about λ/2 at the high frequency end of a grating-lobe free operating band. BAVA elements do not require connection with adjacent elements and are therefore attractive for use in phased arrays with modular construction.

A low profile ultra-wideband tightly coupled dipole array is studied. The antenna elements are fed by Marchand baluns of small size and low cost. A metasurface based wide-angle impedance matching (MSWAIM) layer is introduced to replace the traditional dielectric WAIM, improving the beam scan performance and reducing the antenna profile. The simulation shows that the proposed antenna array can operate over 2.4-12.4 GHz, approximately 5:1 bandwidth with maximum scanning angle of 50o for both E plane and 45o for H plane. The antenna profile above the ground is only 0.578λH at the highest operating frequency. This antenna array can find its application in the forthcoming massive MIMO beamforming systems for 5G.
