General Overview

The photo is ni below shows general overview of the five rectengular spriral antennas. The size of the antenna is shaped according to the wavelength. All antennas are similar in size

Antenna 1:

The first antenna called A90 is designed at the center frequerncy is 90 MHz. A90 has a badwidth is 4.6 MHz. Radiation pattern of the is the same other radioation patterns of rectangular sprial antennas. S parameter graph of this antenna is given below.

Antenna 2:

The first antenna called A94 is designed at the center frequerncy is 94 MHz. A94 has a badwidth is 4.7 MHz. Radiation pattern of the is the same other radioation patterns of rectangular sprial antennas. S parameter graph of this antenna is given below.

Antenna 3:

The first antenna called A99 is designed at the center frequerncy is 99 MHz. A99 has a badwidth is 5 MHz. Radiation pattern of the is the same other radioation patterns of rectangular sprial antennas. S parameter graph of this antenna is given below.

Antenna 4:

The first antenna called A102 is designed at the center frequerncy is 102 MHz. A102 has a badwidth is 4.9 MHz. Radiation pattern of the is the same other radioation patterns of rectangular sprial antennas. S parameter graph of this antenna is given below.

Antenna 5:

The first antenna called A107 is designed at the center frequerncy is 107 MHz. A90 has a badwidth is 5.4 MHz. Radiation pattern of the is the same other radioation patterns of rectangular sprial antennas. S parameter graph of this antenna is given below.
