A meander-line antenna can be realized by bending the conventional linear monopole antenna to decrease the size of antenna [5]. The influence of the meander part of the antenna is similar to a load and the meander line sections are considered as...

H. VolakisPractical methods are, for example, modifying antenna structure by meandering orWideband matching can be done, for instance, by tapering resistive loading on the spiral arms, by infinite coaxial balun along with spiral arms, by the broadbandis done by loading resistances on the slot line, forming an impedance transformer between the antenna impedance and... Spiral Antenna | Cavity-Backed Slot Antennas Spiral antennas are usually circularly polarized. The spiral antenna's radiation pattern typically has a peak radiation directionTo estimate the impedance of the spiral antenna, we can recall Babinet's Principle, which was discussed with respect to slot antennas.
