Some of the most used design techniques to miniaturize an antenna are the vertical meandering and the slotted line. Section 2 describes brief antenna design foundations Section 3 describes simulation and measurements results Section 4 presents a discussion and Section 5 comprises conclusions and references.

To determine the performance of the design parameter, as impedance, resonance frequency, radiation pattern, and polarization, HFSS simulation software has been used and experimental tests under an anechoic camera have been applied.
This work proposes a spiral slotted microstrip antenna, single turn and half turn, whose resonance frequency can be designed along the 700 MHz UHF Band (698–806 MHz) LTE, variable when some antenna dimensions are adjusted.

Particularly, according to one of the states, “the concessionaires and official agents have an essential requirement to give the frequency bands back to the Mexican State, which initially were granted permission to attend the TV broadcasting service, as soon as the transition to the terrestrial digital television (TDT) has already been done, in order to guarantee the efficient use of the radio electric spectrum, as well as encourage a fair competition and an optimal use of the 700 MHz UHF Band”. Īs far as that is concerned, it is a unique opportunity in order to make the end of the old analogic TV and the beginning of the digital TV easy just like in other countries, the Mexican Government has established some changes to telecommunications laws since June 2013.

It is widely known that, a long time ago and nowadays, the frequency bands have been assigned by the government through laws implemented by itself or by owners of big businesses as consequence, the transmitted information quantity using the free space as transmission media (radio communications services) is too much, that is, radio, TV, radio cellular, and so forth, which have saturated the electromagnetic spectrum causing slow communications and ineffective utilization of the radio spectrum, and particularly radio cellular bands are overloaded in most countries this way, a great part of the radio frequency electromagnetic spectrum is used in an inefficient way most of the time, some other frequency bands are only partially or largely unoccupied and the remaining frequency bands are heavily used. This technological advance represents a radio mobile antenna design challenge because it is necessary to design an antenna whose dimensions must be small enough, which satisfies gain, resonance frequency, and bandwidth requirements and is of low cost. Recently, just like other countries, in Mexico, terrestrial digital television has been implemented (analogic shutdown) as a consequence, the 700 MHz UFH Band (698–806 MHz) has been opened to new telecommunications services, particularly wireless mobile communication.
