    Antennas in 10 - 20 GHz frequency spectrum

    I know how to use google sir!! I know that there is antennas are designed in this frequency range but I want to know that if there are what is the application of them (designed MPA's in this high frequency range (10 GHz- 20 Ghz)). in satellite, wireless systems or high data rate... and .... i...

    Antennas in 10 - 20 GHz frequency spectrum

    Hi freinds can anyone help me about antennas (specially microstrip patch antennas) by application in frequency spectrum of 10 - 20 GHz ? I don't familiar with antennas in this frequency ranges and their applications.please help me! Thanks alot.

    microstrip patch antenna dimension

    hi friends as mentioned in Balanis, ANTENNA THEORY AND ANALYSIS DESIGN, when an optimized width for an efficient radiator is W=(C0/2f)(√ (2/εr+1)) The resonant frequency for the TM100 mode is f=(C0/2Leff)(√ (1/εreff)). but when W is adjusted as above, W is larger than the L and this led to that...

    ANSYS and HFSS coupling

    Please leet me change my question ,Ansys 13 and Hfss 13 can be coupled. how is this performed ?

    ANSYS and HFSS coupling

    No it is'nt easier,I have an complex and Cumbersome antenna structure designed in ansys environment which should first analyzed by ansys to extract produced deflections and then this deflections must applied to antenna structure design and analyzed electromagnetically by HFSS !!

    Mems reconfigurable microstrip patch antennas

    I suggest you to be calm, edaboard is a place for ask question and discussion about them,do you know?

    Mems reconfigurable microstrip patch antennas

    I am not agree with your idea, dielectric constant for microstrip antennas should be small toward one so that antenna could be able to radiate.

    Mems reconfigurable microstrip patch antennas

    Hi friends , I want to know that what is the kind of dielectric used in microstrip patch antennas and is it possible to use of silicon oxide or silicon nitride as substrate in microstrip patch antennas? thanks.

    problem in plotting I-V curve in ADS software

    Hi; excuse me my friend,I did explained my problem almost bad,I have plotted MOSFET I-V curve for swepted VDS and VGS and I have family of curves but I want to plot "VGS=related value" phrase beside any I-V curve. thank you.
