Antena merupakan piranti transmisi yang penting dalam system penerima sinyal televisi, sebab tidak dimungkinkan lagi jika kabel tembaga dipakai sebagai saluran trasmisinya yang terbatas akan jarak. Antena televisi yang ada di pasaran sekarang ini sudah banyak jenisnya, Sejauh ini yang paling banyak beredar di pasaran yaitu antena televisi direksional yang kebanyakan terbuat dari bahan alumunium. Antena tersebut memfokuskan daya terimanya ke arah tertentu, sehingga jika kita mengarahkan ke satu arah, maka daya terimanya menjadi besar dan arah yang lain dayanya menjadi kecil, Ini disebabkan karena letak stasiun pemancar televisi yang letaknya sangat jauh, kemudian kondisi alam antara stasiun pemancar banyak gunung, Melihat fenomena tersebut di atas, pada tugas akhir ini akan dirancang sebuah antena pemancar televisi yang diharapkan memiliki gain yang cukup besar.

“…where αnm is the attenuation, aeff is the circular patch antenna radius, and εreff is the effective relative dielectric constant. Next, we take a look at folded dipoles as shown in Figure 15, which have been implemented in both free space [64] and printed forms. In the free space (nonprinted) version, the author of [64] fabricated a soldered folded dipole.…”

In the last few years, the demand for power has increased; therefore, the need for alternate energy sources has become essential. Sources of fossil fuels are finite, are costly, and causes environmental hazard. Sustainable, environmentally benign energy can be derived from nuclear fission or captured from ambient sources. Large-scale ambient energy is widely available and large-scale technologies are being developed to efficiently capture it. At the other end of the scale, there are small amounts of wasted energy that could be useful if captured. There are various types of external energy sources such as solar, thermal, wind, and RF energy. Energy has been harvested for different purposes in the last few recent years. Energy harvesting from inexhaustible sources with no adverse environmental effect can provide unlimited energy for harvesting in a way of powering an embedded system from the environment. It could be RF energy harvesting by using antennas that can be held on the car glass or building, or in any places. The abundant RF energy is harvested from surrounding sources. This chapter focuses on RF energy harvesting in which the abundant RF energy from surrounding sources, such as nearby mobile phones, wireless LANs (WLANs), Wi-Fi, FM/AM radio signals, and broadcast television signals or DTV, is captured by a receiving antenna and rectified into a usable DC voltage. A practical approach for RF energy harvesting design and management of the harvested and available energy for wireless sensor networks is to improve the energy efficiency and large accepted antenna gain. The emerging self-powered systems challenge and dictate the direction of research in energy harvesting (EH). There are a lot of applications of energy harvesting such as wireless weather stations, car tire pressure monitors, implantable medical devices, traffic alert signs, and mars rover. A lot of researches are done to create several designs of rectenna (antenna and rectifier) that meet various objectives for use in RF energy harvesting, whatever opaque or transparent. However, most of the designed antennas are opaque and prevent the sunlight to pass through, so it is hard to put it on the car glass or window. Thus, there should be a design for transparent antenna that allows the sunlight to pass through. Among various antennas, microstrip patch antennas are widely used because they are low profile, are lightweight, and have planar structure.

“…RF energy is harvested from the RF emitted by sources such as radio and TV signals, cell phones, WiFi communications and microwaves [38,39,40]. An energy harvesting system consists of two main subsystems, one is the receiving antenna, which functions to capture ambient RF energy to power up the integrated embedded system and second subsystem is the rectification circuitry, which converts the input RF power into DC output power efficiently [41].…”

Wireless sensor networks (WSNs) design requires multidisciplinary approach in the field of wireless communication, embedded systems, networking, digital signal processing, hardware and software engineering. Major factors to influence the WSNs design are hardware and software constraints, scalability, cost, transmission media, network topology and power consumption etc. Most of WSN nodes are battery powered. With the limited capacity of batteries to power WSN nodes, need of energy harvester or scavenger is required to harvest or scavenge energy from the environment to improve the life-time of the sensor node. The harvested or scavenged energy is converted by power converters to recharge the sensor nodes or for the storage devices. This paper gives current developments of energy harvesting technologies, power converters and storage devices proposed by various researchers in WSNs along with some open research problems.
