A compact wideband microstrip array antenna with a squint beam is introduced without the matched load. Its measured beam is at 10 offset to the broadside with a measured gain of 12 dB at 10 GHz. The measured impedance bandwidth (voltage standing wave ratio (VSWR) 2) is over 16%, which agrees well with the simulated one. It is a low-cost wideband design with compact simple structure, suited for military and commercial application.
As the appearance of local dimming technique,the current existing test methods are not suitable for testing the power consumption of the LCD TVs using the local dimming technique any longer.A test method appropriate to LED backlight LCD TVs using the local dimming technique is proposed in this paper,and then the test software is developed.The results demonstrate that the test software developed can show the real average power consumption of the LCD using local dimming technique,and by normalization the power consumption become comparable for not only local dimming LCD TVs but global dimming LCD TVs.Using the software developed in this paper,the ratio of power saving is clear when an LCD TV using the local dimming technique compared with one without local dimming technique.
