“…The antenna's polarization can illustrate circularly polarized waves [16,17]. Antenna polarization refers to the trajectory of the power plant vector break in a fixed position in space with time motion, according to the polarization form of the antenna can be divided into three different forms: line polarized antenna, far polarized antenna, and elliptically polarized antenna [18][19][20].…”

Microstrip antennas are widely used in people's daily life. Microstrip antenna has the advantages of low cost, low profile, small space occupation, and high conformal capability. So the design of microstrip antennas can be encountered in daily life. Microstrip antennas include the military, aerospace, medical, and so on. Microstrip antenna has a wide research space. The three microstrip antennas, U-shaped open slit laminated microstrip antenna, dual frequency circularly polarized laminated microstrip antenna, and non-radiating edge-fed broadband double-layer microstrip patch antenna are mainly introduced to understand the research progress and expectation of today's microstrip antennas. This paper firstly introduces the basic theoretical concept of microstrip antenna, then introduces the cavity mode theory, and then mainly lists and introduces three kinds of designed microstrip antenna structures. Finally, these three types of microstrip patch antennas are analyzed. And the advantages, disadvantages, and development fields of the corresponding types of microstrip patch antennas are introduced. The application determines the structure of the method used, and each design has its strengths. Microstrip antennas always have room for research, and continuous research will be applied to more fields.

“…The simulation VSWR curves with different values of gap are plotted in Figure . The small changes in the width of the gap between the ground and the patch have a main effect on the impedance matching of the antenna . By adjusting the length of gap, the electromagnetic coupling between the lower edge of the patch and the ground plane can be obtained and their notch bandwidth can be controlled .…”

near the influential materials if the proximity effect is either an advantage or a disadvantage for an antenna system, depending on the size of an element materials, and small antenna is a small example ceramic chip antenna encapsulated in a cubic millimeters, using ESA and PSA as well. When designing a chip ceramic ESA, the dimensions of the mobile terminal device, the space for mounting the antenna, the space to be occupied by the antenna, and the antenna size [11]. FUNDAMENTAL LIMITATIONSmall antennas to reduce its size, gain and antenna efficiency degrade, and bandwidth tends to be narrower. Body limiting small antenna could have effective aperture as high as 98% of a half-wave dipole antenna when the antenna is optimally adapted to the load. There seems to be no limitation in reducing the size of the antennas, so did the antenna can be perfectly adequate. Perfect matching is impossible when an antenna is extremely low [12].Furthermore, the losses existing in the antenna structure and the corresponding circuit does not exceed the radiation resistance, which reduces the effective apertures that the efficiency of radiotherapy. With regard to the impedance of the antenna, the increase and decrease in the reactive component of the resistive elements results in a high Q factor and bandwidth will be reduced as a result. Reducing the size of the antenna and also makes them Q and bandwidth [13].The parameters affecting the fundamental limitations of small antennas are antenna Q (quality factor) of the bandwidth ratio g, the antenna size ka, where a is the radius of a sphere surrounding and antenna [14].ka is much smaller than unity. Q is proportion to ka ð Þ -3 .RBW is proportion to ka ð Þ 3 , RBW nearly equalsg is proportion ka ð Þ 4 . CONCLUSIONIn a number of applications such as wireless Personal Computer Memory Card International Association cards, ESA's have been implemented that have adequate impedance bandwidth, and they are well matched. Some case matching the impedance bandwidth would decrease or in some case increase. Such that main fundamental limitation on antennas size versus impedance bandwidth brigs order to what can appear to be mysterious changes in antenna performance [15][16][17]. It should be noted that a small antenna, that is, appropriately designed to satisfy the system requirements should not be near certain materials so that designed antenna performance is substantially harmed. It can be said generally that the smaller the antenna becomes, the large the influence of such nearby materials is likely to be.

“…The exclusive advantages offered by UWB technology for short range communications, like increased data rate and reduced power, have brought about a revolutionary growth into the research of UWB components. One such antenna design is a monopole antenna, which is under consideration due to its advantageous properties like small size, light weight, low cost, and omnidirectional radiation pattern [1][2][3][4]. A major problem faced by the UWB systems is the unwanted electromagnetic interference (EMI) from existing in-band RF sources like Wi-MAX, WLAN, ITU, etc., which are pockets of high-power output.…”

This manuscript proposes an Ultra-Wide band (UWB) Filtering Antenna (Filtenna) with application-based notches at Wi-MAX (3.3-3.7 GHz), , and ITU (7.725-8.275 GHz) bands. Initially, a monopole antenna is designed. To enhance bandwidth and bring about impedance matching, its ground plane is modified by introducing a triangular shaped defected ground structure (DGS) under the feedline, smoothening of upper edges of the ground plane, and a rectangular DGS. Later, the triple notched bands is created at 3.5 GHz, 5.5 GHz and 8 GHz by utilizing the notches generated by Inverted-U shaped defected microstrip structure (DMS) on the patch, U-type DMS on feedline, and C-shaped resonator adjacent to the feedline respectively. The filtenna is an omnidirectional radiation pattern antenna which works within the proposed frequency band of operation having low insertion loss and good selectivity. Also, the VSWR is found to be < 2, and peak gain is found to be 4 dBi. While studying the proposed filtenna, the simulated and measured frequency responses were observed to be in almost unison as if following each other.
