A compact multiband 40 degree split beam antenna system for a wireless network is disclosed. Each band employs a 3 column array with a special 3 output feed network. The 3 output feed network employs either a broadband 90 degree hybrid coupler with a 180 degrees splitter, or 2 broadband 90 degree hybrid couplers. The arrays employ dipole antenna elements, patch antenna elements, or a combination of both types. The antenna may exhibit 35 to 40 degrees horizontal beamwidth.
