For the analysis of conformal array antennas the knowledge of the mutual coupling among the radiating elements and the radiation patterns of individual elements are essential ingredients.

The first step in the analysis of conformal antennas is to find the electromagnetic field on the surface or in space in the presence of an arbitrary shaped body. In section 2, conformal antennas are briefly introduced.

In addition, in order to provide an overview of the present research status, a literature review is carried out. In section 3, a general study of conformal antennas is presented.

Several types of conformal antennas are studied, being them divided into two groups: singly and doublyFile Size: 2MB. Method of Lines Numerical Analysis of Conformal Antennas Article in IEEE Transactions on Antennas and Propagation 52(6) - July with Reads How we measure 'reads'.

Owing to their electrical and mechanical attractive characteristics, conformal microstrip antennas and their arrays are suitable for installation in a wide variety of structures such as aircrafts, missiles, satellites, ships, vehicles, base stations, by: 4.

Tunable antennas refer to antennas who have one or more antenna performance characteristics, often just the operational frequency is investigated, that can be changed, or tuned, within some continuous range. Such behavior is often achieved by the thoughtful placement of slots, pins.

A plethora of design approaches of flexible and conformal antennas were reported in the literature including Electro-textile, paper-based, fluidic, and synthesized flexible substrates.
