Antenna Pattern Distortion due to 2 antenna placed in near vicinity

Because i need 180 deg coverage i have to use both antennas together.
The 3dB beamwidth of 90deg of both antennas give me 180deg coverage.
And i expect the gain to be 3dB down at 90deg but instead i am getting
gain less by 10 to 15 dB. Is there any way i can get less ripple at
the overlap?
