    I am new to the field of radio transmission. I working on a project that involves transmission of 434 Mhz signal through a transmitter receiver pair. I want a directed antenna so that they can communicate only through reflection from other surface. I need it to be low powered as i require a battery and the range be 150 m (80 m approx if it receives from a reflection.) . Which type of antenna should i use ?
    Also can you explain how can i create a directed antenna on a PCB or board.

    a small yagi antenna would work. check the ac6v website, they have a whole sefction on antenna design and building. that would be a 70 cm. yagi antenna.

    Sorry to burst your bubble. You can do what you want with a Yagi type of directional antenna. Bad news for you is that at 433MHz, the antennas will be roughly 35cm wide by 100 to 200cm long. Not possible to make a directional antenna on a PCB that is a few cm on a side...

    You might do better at 2.4 or 5.8GHz.
