What is difference in between the E-plane tee and H-plane tee?
The E-plane and H-plane are planes of reference for linearly polarized antennas, waveguides and other microwave devices. A waveguide which has three independent ports in a microwave circuit is known as a TEE junction. The output of E-plane Tee is 180 degrees out of phase and the output of H-plane Tee is in phase.
What is the use of H-plane tee?
H-Plane Tee (Shunt Tee) On the other side, if input is fed at port-3, the waves get split equally into port-1 and port-2 with in-phase and will have same magnitude. These properties of H-plane tee is used in waveguide power combiner and power divider. S matrix of H-plane tee is same as mentioned for E-plane tee.
What are series and shunt tee?
An H-plane tee is a waveguide tee in which the axis of its side arm is “shunting” the E field or parallel to the H field of the main guide as shown in Fig. It can be seen that if two input waves are fed into port 1 and port 2 of the collinear arm, the output wave at port 3 will be in phase and additive.
Why E and H plane tee are called as 3dB splitter?
i.e. an input at port 3, is equally divided between port 1 and 2, but introduces a phase shift of 180° between the two outputs. Hence E plane Tee acts as a 3dB splitter.
Why H-plane tee is called 3 dB splitter?
Also, when powers entering port 1 and 3 are in phase opposition, maximum energy comes out of port 2. An input at port 2 equally divides between ports 1 and 3 but introduces a phase shift of 180° between the outputs. Hence E-plane Tee also acts as a 3dB splitter.
What is H-plane and V plane?
The magnetizing field or “H” plane lies at a right angle to the “E” plane. For a vertically polarized antenna, the H-plane usually coincides with the horizontal/azimuth plane. For a horizontally polarized antenna, the H-plane usually coincides with the vertical/elevation plane.
Why is e plane tee called Series?
T his E-plane Tee is also called as Series Tee. As the axis of the side arm is parallel to the electric field, this junction is called E-Plane Tee junction. This is also called as Voltage or Series junction. The ports 1 and 2 are 180° out of phase with each other.
Why H Plane tee is called 3dB splitter?
Why is e-plane tee called Series?
What is an E-H plane tee junction?
An E-H Plane Tee junction is formed by attaching two simple waveguides one parallel and the other series, to a rectangular waveguide which already has two ports. This is also called as Magic Tee, or Hybrid or 3dB coupler.
What is the s13 = s23 matrix of H plane tee?
S matrix of H-plane tee is same as mentioned for E-plane tee. The same is mentioned equation- (1) and equation- (2) in figure-1 except here S13 = S23. As they are poor in providing good match, tuning screw is used to adjust the reactance of the system to obtain perfect impedance match.
What is H-plane tee?
Since the axis of the sidearm is parallel to the plane of the H field of the main waveguide, it is called an H-plane Tee. A rectangular slot is cut along the narrow dimension of a long waveguide, and a sidearm is attached as shown in the figure below.
What is the difference between in-phase and additive in H plane tee?
In H plane tee, when two inputs are fed into port-1 and port-2 of the arms (collinear), output at port-3 will be in phase and also additive in nature. On the other side, if input is fed at port-3, the waves get split equally into port-1 and port-2 with in-phase and will have same magnitude.
