phase delay from u2212 2 radians to u2212 7 radians the beamform 600 may accordingly be applied to cook a wide dimensioned food in the oven cavity 210 for example the beamform 700 may be applied to cook multiple foods spaced apart from each other in the oven cavity 210 for example the waveform 800 of fig8 was formed using three transmit patch antennas such as the patch antenna 335 u2032 spaced 10 units of length apart the relative phase delay is controlled at u2212 7 radians the beamform 800 includes microwave signals concentrated along two paths 810 and 820 the direction of the paths 810 and 820 are angled apart by the angle 830 which is an acute angle the paths 810 and 820 are also angled apart by a second angle 840 which is an acute angle from fig6 and 8 it may be seen that in comparing the beamform 600 to beamform 800 increasing the number of transmit patch antennas from 3 to 5 increases the directionality of the paths of the beamform increasing the number of transmit patch antennas from 3 to 5 also causes the paths of the beamform to be narrower and more pointed toward the food to be warmed referring additionally to fig9 a system 900 for monitoring and controlling the microwave 200 according to an example embodiment is now described the system 900 allows a user to view images captured by a camera 905 in the microwave 200 on a device such as a.
