A slot antenna and a dielectric resonator antenna (DRA) were combined to effectively design a dual-band dielectric resonant antenna
for C- and X-band applications, but this was achieved through a complex multilayered structure .
Figure.1 shows a four-arm spiral antenna proposed by Kilgus, it is the resonant antenna
. This antenna is composed by four spiral arms, each spiral arms length is Ml/4 (M is an integer).

From the CPW ENG MTL unit cell discussed in Section 2, the configuration of the proposed wideband resonant antenna
is shown in Figure 3.
Therefore, the coplanar stripline dipole antenna with a short bias line scheme can be characterized as a standing wave antenna or a resonant antenna
owing to the reflections at the bias line terminations.
A DRA is a resonant antenna
fabricated from low loss microwave dielectric material whose resonant frequency is predominantly a function of size, shape and material dielectric constant.
The proposed fractal tree-shaped MSA has measurements of L x W is acquired to the resonant antenna
at multiple frequency appeared in Figure 2, which is printed on the substrate of dimensions 80 L x 100 W x 1.6h [mm.sup.3].

A slot antenna and a dielectric resonator antenna (DRA) were combined to effectively design a dual band dielectric resonant antenna
for C and X band applications 12], but this was achieved through a complex multilayered structure.
The zeroth-order resonant antenna
has a monopolar radiation pattern, which is similar to that of the traditional monopole antenna; thus, it is suitable for adoption on wireless devices requiring an omnidirectional radiation characteristic.
