Quazi-BowTie Antenna

Most of you know for BOW TIE antenna for TV reception..

so few days back i decided to try to build one for wi-fi 2.4.

This time i also use aluminum 1.5mm electric wire..even i can use copper wire 

just to see how work with aluminum...

anyway most of antennas are build with aluminum.

measures are standard ... distance of each element by holder is half wave L/2

size of element is full wave , angle in element is 60 deg

Dimensions are  standard for bow tie  L/2 distance from elements and L/4 until curved

WELL yes Inc-royavle ..pff incredibile 16dB with reflector and reletive easy to build!

I want to build this antenna, so I have some questions/suggestions:

1. What is impedance of this antenna? Can it be connected directly to 50 Ohm cable?
2. What are dimensions of reflector and spacing between it and directors in simulation?
3. Length of the director's parts should be 31mm to change working frequency to 2.45 GHz.
4. If a copper wire is used, the antenna elements should be soldered together.
5. How about make simulation with straight "V" directors (each arm 61mm length, connected with angle 30 degrees)?

1)- impedance=250-300 Ohm

2) - spacing between it and directors<<lambda/2

3)-no

4)-yes

5)-it must to be simulated
