Abstract A compact multiband antenna is designed using HFSS on FR4 substrate with permittivity of 4.4. The dimension of substrate is 50 75 1.6 mm3. An M-shaped antenna with symmetrical slots is proposed in this paper. Inset feeding is made to make it simple and compact. Multibands are obtained in S11 versus frequency plots. Lower bands are obtained from 3.7–3.9 to 5.5–5.9 GHz. The higher bands are 9.3–10.3, 11.4–12.7, and 12.9–13.5 GHz. The higher bands are highly useful for X-band and Ku-band radar applications.

Ku-band C-band Microstrip patch antenna
1 Introduction In recent years, wireless communication systems have increased rapidly, and the demand for higher data rates has been of prime importance [1–5]. With wireless communication heading toward advanced technologies, usage of smaller and multiband antennas is the need of the hour. Microstrip antennas are the best candidates for the present requirement of consumers for multiband wireless phones validating more than one network [6–8]. Apart from these, variegated work on microstrip antennas suitable for radar and satellite communication applications has been accomplished [9–11]. This field has been largely supported by the microstrip antennas due to its distinct advantages such as low profile, low cost, ease of fabrication, and ease of integration with accompanying electronics. Also, these provide multiband operation with better return losses.

In this paper, an M-shaped microstrip patch antenna has been designed for satellite and radar applications. Three different slots were made in the patch. Apart from these, two symmetric triangular slots were made for inset feeding. Detailed parametric studies were carried out for different configurations of patch antenna. Multibands with different return loss and impedance bandwidth are obtained from the design. The paper is organized as follows. Section 2 describes antenna design and characteristics. Results and discussion are made in the Sect. 3. Conclusion is made in Sect. 4.
2 Antenna Design Figure 1 represents an antenna that can be utilized in various radar applications. To design an M-shaped patch antenna, first a rectangular patch antenna is considered and a U-shaped patch is created by cutting out a rectangular slot from the rectangular monopole antenna. After creating a U-shaped patch, two rectangular slots are cut out from the corners of U-shape, as shown in the Fig. 1 above, thereby creating an M-shaped monopole patch antenna. The dimensions for the
